Reveal Conversion Friction With Clarity
I don’t actually use this as an SEO tool, but it is the most useful SEO tool I use. It’s a free heatmap and session recording platform by Microsoft, called Microsoft Clarity.
If visitors do nothing when they arrive, then the rankings don’t matter, and ranking reports won’t tell you that. I manage SEO for 8 WordPress plugins; 1 of them, Post SMTP, is used by over 300,000 active users. We checked our pricing page in Clarity and found that users were repeatedly clicking on the monthly/yearly switch, but never on Buy Now. There was traffic, but it wasn’t what I was used to. The page was leaving people in the lurch when they were about to pay.
I can also now see if visitors from AI assistants such as ChatGPT and Copilot are converting, so I can see if that new traffic is converting. It’s a great tool to use for any founder, as it is free and can help turn vague traffic numbers into fixes.

Earn Editorial Backlinks
Connectively. Most people don’t categorize it as an SEO tool at all; they think of it as a PR platform, which is exactly why it’s underused in the SEO community. It connects experts with journalists looking for sources on active stories, and getting selected earns a genuine, editorially vetted backlink and attribution on a real publication.
How it benefits my SEO specifically: over 18 months, consistent daily use—about 30 minutes responding to relevant queries—has produced 24 publications on sites with real domain authority. Those links carry more weight than negotiated guest posts or directory submissions because they’re earned through genuine editorial selection, not a transaction. More importantly, they built the third-party verification that got me cited in Google’s AI Overview and ChatGPT responses for my expertise area, something no amount of on-page keyword optimization would have accomplished alone.
Why I’d recommend it to others: it rewards genuine expertise rather than budget or link-building volume, which makes it accessible to smaller businesses that can’t compete on paid link acquisition. The tradeoff is patience; results aren’t instant, but the links that come from it survive algorithm updates because they look, and are, genuinely earned rather than manufactured.

Audit On-Page Elements With Detailed SEO
One lesser-known SEO tool I find incredibly useful is Detailed SEO Extension. It’s a simple Chrome extension, but it saves a surprising amount of time when I’m reviewing pages.
With one click, I can quickly check title tags, meta descriptions, headings, canonicals, robots directives, structured data, internal links, and other important on-page elements without digging through the
I find it especially useful during competitor research and quick SEO audits because it helps me spot issues or patterns immediately. For example, I can see how competitors structure their headings, which schema types they use, or whether a page has indexing or canonicalisation problems.
I’d recommend it because it doesn’t try to replace a full SEO platform. Instead, it makes everyday SEO checks faster, which is particularly valuable when you’re reviewing dozens of pages or competitors.

Map Follow-Up Queries With AlsoAsked
My go-to underrated pick is AlsoAsked. It maps real “people also ask” style question chains straight from actual search behavior, so instead of guessing what to cover in a piece, I can see the exact follow-up questions real users type after their first search. It’s saved me hours on content briefs and FAQ sections, and it consistently surfaces long-tail angles competitors miss because it’s not a mainstream keyword tool people default to. I’d recommend it to anyone doing content or digital PR who wants topic ideas grounded in real query behavior instead of just search volume.

Mine Paid Search Terms for SEO
Use Google Ads Search Term Reports for your SEO research. Most SEO teams never touch paid search reports, but Google Ads search terms can unveil real queries that convert and give insight into volume and demand.
We’ve found keyword opportunities that never showed up in traditional research tools like Ahrefs or Semrush, but with obvious conversion intent. This data is at your fingertips if your client or agency is already running paid search, but almost no SEO teams ask for it.
Andy Hendricks, Head of Search, Grey Matter
Find Attainable Keywords With LowFruits
LowFruits is useful because it finds low-competition keywords where weaker sites already rank, revealing search opportunities that larger competitors may overlook.
I recommend LowFruits because it makes keyword research more actionable for smaller or newer websites. Instead of chasing high-volume terms dominated by authoritative domains, you can identify queries where the existing results have weaknesses in authority, content depth, or relevance. The best approach is to use LowFruits to find the opportunity, then manually assess search intent and create a page that is substantially more useful than the current results.
Use LowFruits to uncover realistic keyword targets, but prioritize opportunities based on search intent and business value. The goal is not simply to rank for an easy keyword—it is to find an attainable query that can bring qualified visitors who are likely to convert.

Uncover Crawl Flaws With Bing Tools
Having worked in marketing for over 35 years and founding ForeFront Web, the resource I constantly see people ignore is Bing Webmaster Tools.
Most marketers rely entirely on Google Search Console, but Bing offers sharp diagnostic reports on crawl issues, sitemaps, and indexability. It gives you a direct look at your site’s technical foundation under the hood.
In our campaigns, cleaning up technical crawl errors is often the fastest way to boost rankings. Running these audits helps us catch broken links and indexation flaws that might otherwise go unnoticed.
I recommend integrating it into your regular toolkit right away. It is completely free and uncovers easy technical fixes that improve your site’s performance across all search engines.
Scott Kasun, Digital Marketing Executive, ForeFront Web
Inspect Rendered Pages With Custom Scripts
Screaming Frog’s custom JavaScript extraction. Everybody knows Screaming Frog. Almost nobody I talk to uses that specific feature, and it turned the tool from a crawler into something closer to a scriptable inspector.
The standard use of a crawler is to collect what the crawler already knows how to collect. Titles, status codes, canonicals, word count. Custom JavaScript extraction lets you run your own snippet against every rendered page and store whatever it returns as a column. That is a small-sounding capability with a large consequence, because it means any question you can answer by looking at one page, you can now answer across 40,000 pages.
Real examples from our work. We had a client whose product pages sometimes rendered a price and sometimes rendered a placeholder depending on an inventory call, which nobody had noticed because it looked fine on the pages anyone checked by hand. A four-line snippet reading the price element found 1,140 pages serving an empty price to the crawler.
Another one: a French client where accented characters were being mangled on a subset of templates. Impossible to find by sampling, trivial to find by extracting the H1 across the whole site and grepping the output.
We also use it to pull the internal link count from the main content area only, excluding nav and footer, which no standard crawl report gives you and which is the number that actually matters when you are diagnosing why a page gets no internal equity.
Why I recommend it: most SEO tooling answers the questions the vendor decided were important. This one answers the question you have today. The barrier is that people assume it needs real development skill, and it does not. If you can write a document.querySelector line, you can use it.

Diagnose Core Web Vitals With GTmetrix
GTmetrix is useful because Core Web Vitals problems rarely tell you their cause from the metric alone.
A poor Largest Contentful Paint result might come from an oversized image, render-blocking resources or slow server response. GTmetrix gives us Lighthouse-based performance data alongside its Structure audits and Waterfall Chart. The Waterfall is especially useful because we can inspect individual network requests and see which images, JavaScript, CSS or third-party resources are delaying the page.
We used that process on a client site where several important landing pages had weak LCP performance. The investigation showed that large above-the-fold images were loading later than they should. After resizing the files, improving image delivery and adjusting resource priority, LCP on the affected template dropped from roughly 4.6 seconds to 2.3 seconds in our tests. GTmetrix also offers a free plan, making it a practical starting point for SEO freelancers who cannot justify expensive software subscriptions early in their careers.
You do not need an expensive SEO platform to start doing serious technical work and GTmetrix gives you enough data to prove it.
Matt Bowman, Founder, Thrive Local
Track SERP Shifts in Spreadsheets
What I recommend is a plain spreadsheet tracking manual SERP observations over time, unglamorous next to any paid platform, but it caught a pattern shift in how Google displayed results before automated tools reported it days later. Watching actual search results change firsthand, not through a dashboard summarizing them after the fact, gave us an earlier read on a featured snippet shift than any tool alert did that quarter. It benefits the work because automated tools are built to report common patterns, while manually watching results lets you notice the unusual ones nobody’s built a report for yet. I’d recommend it less as a replacement for real tools and more as a habit worth keeping alongside them, since noticing things early is still mostly a human skill.
Tristan Harris, Sr. VP of Marketing, Next Net Media
Broaden Map Listings With Competitor Insights
One of the lesser-known tools we’ve found useful is the GMB Everywhere plugin for Google Chrome, particularly for local businesses. It takes the guesswork out of related service areas that your competitors might be able to target and gives you ideas about additional areas and categories you can target. We had a service-based client receiving plenty of website traffic, and users were reaching the booking page, but once we added additional related categories, their views went up even more.
I would recommend it to others as it saves time looking through all the potential categories to see what fits your local map listing. You can essentially spy on and audit your GMB competitors to make sure you are on top of your map listing optimisation game.
Maddison Ryan, Founder, The Digital Hub
Discover Local Gaps Through GMB Everywhere
One lesser-known tool I use a lot is the GMB Everywhere Chrome extension. I run a marketing agency for cleaning companies, and local SEO lives or dies inside Google Business Profile.
It lets me quickly see what categories competitors are using in Google Maps. For a maid service, that can reveal whether top competitors are positioned as “House cleaning service,” “Commercial cleaning service,” or something else entirely.
I used this same kind of local visibility thinking when growing Love My Maids, and now we apply it for Cleaning Business Growth clients. If a cleaner wants more move-out cleaning jobs, their GBP categories, services, website pages, and review language all need to support that intent.
I recommend it because it’s simple, cheap, and practical. You don’t need a massive SEO platform to find obvious local SEO gaps your competitors are already showing you.
Ginger Whitson, Founder & CEO, Cleaning Business Growth
Boost Clicks From Search Console Data
One tool I don’t hear talked about enough is Google Search Console’s Search Analytics filter by “impressions with low clicks.” After 20 years in digital strategy, I’ve found that most business owners obsess over rankings and completely ignore this goldmine.
At Chabot, I use it to find pages that are already showing up in search but failing to earn clicks. That usually means the title or meta description isn’t doing its job — the page exists, Google knows it, but nothing is compelling the reader to choose it. A quick rewrite often moves the needle faster than building new content from scratch.
For a law firm client we work with, this exact approach helped surface a few underperforming service pages. We tightened the copy to match what people were actually searching for, and leads increased noticeably without touching the page structure at all.
The reason I recommend it: it’s free, it’s already connected to your site, and it tells you where effort already exists but isn’t converting. For business owners who want clarity over complexity, that’s the kind of focused action that supports real, sustainable growth.
Alyx Lofton, CEO & Founder, Chabot Business Solutions
Eliminate Duplicate Service Pages
Screaming Frog. Most people know it exists, but very few contractors actually use it—and that’s a mistake I see constantly when auditing home service websites.
What makes it underrated isn’t the broken link detection (everyone mentions that). It’s the duplicate content crawl. I’ve pulled Screaming Frog reports for HVAC clients and found 30+ near-identical service pages that were quietly cannibalizing each other in search rankings. The client had no idea. Fixing that alone moved the needle faster than months of new content creation.
For trades businesses specifically, it’s great at surfacing missing or duplicate meta titles across city pages—something almost every contractor site gets wrong when they scale into new service areas.
Run it quarterly. Export the full crawl into a spreadsheet, sort by status code, and start with your 4xx errors first. It’s free up to 500 URLs, which covers most smaller contractor sites completely.
Jennifer Bagley, CEO, CI Web Group
Compare International SERPs With SEOquake
One lesser-known SEO resource I find particularly useful is the SEOquake browser extension. When you work with multiple markets, one of the challenges is understanding what users actually see when they search from different countries and in different languages. Search results are highly contextual, so relying on what appears in your own location can give you an incomplete picture of the competitive landscape.
Being able to quickly change the country and language when checking search results makes this kind of research much more efficient. It helps us compare how brands rank across markets, identify local competitors that may not appear in our default search results, validate keyword assumptions, and understand whether the same content strategy works equally well in different regions.
What I particularly value about tools like SEOquake is that they remove friction from repetitive research. Individually, changing settings or running another search may only take a few minutes, but those minutes add up when you are analyzing dozens of queries across several markets.
I would recommend it to international marketing teams in particular. Good SEO decisions depend on seeing the search environment as your audience sees it, rather than assuming your own SERP is representative of everyone else’s.
Viktoriia Cherednyk, Chief Marketing Officer, SupportYourApp
Measure AI Overview Citation Share
The tool we reach for that most SEOs skip is a SERP-feature tracker that logs which of our own pages hold an AI Overview citation week over week, not just a rank position. Rank alone told us nothing about whether an answer engine was actually quoting us, and we found three pages ranking top five with zero citation share, which meant the content answered the query but not in a citable shape. Restructuring those pages around a single-sentence answer block near the top lifted citation presence on two of the three within a month. It changed how we brief writers: every new page on our AEO work now opens with an extractable answer before any narrative context.
Kartik Chugh, Cofounder, FORKOFF
Monitor Index Status Through URL API
One lesser-known tool we rely on is Google Search Console’s URL Inspection API. Most people use Search Console through the dashboard and stop there, but very few actually pull data through the API to monitor indexing status and rich result eligibility at scale across hundreds of URLs at once. Checking pages one by one in the dashboard just isn’t realistic once a site has any real size to it.
The benefit for us has been catching indexing problems days or sometimes weeks before they’d normally surface. We run it on a schedule to flag pages that drop out of the index, lose rich result eligibility, or hit a coverage issue, instead of waiting to notice a traffic dip and then trying to reverse engineer what happened. For a site with hundreds of pages, that early warning has saved real traffic that would otherwise have quietly bled out before anyone caught it manually.
I’d recommend it to anyone managing SEO for a site with more than a handful of pages, mainly because it shifts you from reactive troubleshooting to actually catching problems while they’re still small. It requires a bit of technical setup since it’s API access rather than a plug-and-play dashboard, but even a simple script checking a batch of URLs weekly gives you visibility most people are missing entirely by relying on the standard Search Console UI alone.
Ankita Pathak, Founder, OneMetrik
Test Brand Citability Through AI Search
Most of the SEO tools everyone recommends are built for the old game, tracking rankings for keywords people type into Google. The tool that has actually mattered for us lately is Perplexity’s own search, used not as a research assistant but as a diagnostic. I run our target questions through it the same way a customer would and read exactly which sources it pulls from and how it phrases the answer. That tells you in real time whether AI engines see your brand as a citable source or not, which regular rank trackers cannot show you at all.
We started doing this about six months ago as our content team shifted from writing for Google’s ten blue links to writing for answer engines like ChatGPT and Perplexity. The tactic is simple: pick your 20 highest-intent questions, run each one through two or three AI search tools, and log whether you show up and how you’re framed. We found we were completely invisible on questions where our blog content buried the direct answer three paragraphs down. Rewriting those pages to lead with a clear, quotable answer got us cited within weeks.
I’d recommend this to anyone doing SEO or AEO work right now because it costs nothing and takes 20 minutes, but it tells you something no paid tool will: whether the AI systems your future customers are actually using can find and trust you. That’s the metric that matters going forward, not just rank position.
Rick Elmore, CEO, Simply Noted
Extract Custom Site Data With XPath
One I use a lot is Screaming Frog’s Custom Extraction feature.
Screaming Frog itself obviously isn’t obscure, but surprisingly few SEOs use Custom Extraction properly. You can use XPath, CSS selectors or regex to pull almost anything from a site into your crawl – author names, publication dates, product data, internal-link modules, schema properties, breadcrumb depth, specific page-template elements, even whether certain copy blocks appear across thousands of URLs.
The benefit is that it turns Screaming Frog from a crawler into a custom SEO database. Instead of manually checking 500 pages or buying another specialised SaaS tool, I can extract the exact signal I care about, segment the site and find patterns quickly.
I’d recommend it because most serious SEO problems are site-specific. Generic audit tools give you generic checks; Custom Extraction lets you interrogate the site around an actual hypothesis you’re trying to prove or disprove.
Blake Smith, Founder, Performance Agency
Reverse-Engineer AI Sources With Perplexity
Having spent over a decade in digital marketing helping law firms build authority across traditional and AI search, my favorite lesser-known resource is Perplexity for reverse-engineering AI search citations.
We use it to run conversational queries and see precisely which local references, niche pages, and digital sources the engine pulls to generate its recommendations.
Targeting those exact authority signals helped us build strategic content that took attorney client Jon Marko to the number one searched attorney in the Detroit metro area for his practice areas.
I recommend it because modern search is shifting toward AI answer engines, and analyzing citation sources gives you a clear roadmap to build genuine trust instead of chasing vanity metrics.
Paul Mackiewicz, Founder & CEO, Honorable Marketing
Expose JavaScript SEO Flaws Fast
One under-the-radar SEO tool I love is View Rendered Source, a Chrome extension that shows you what a page looks like before and after JavaScript gets its hands on it. That sounds nerdy, but it’s ridiculously useful because a page can look totally fine to a human while important copy, links, titles, or canonicals are getting mangled behind the scenes. Instead of staring at source code like you’re defusing a bomb, you can quickly see what changed. It’s especially handy on JavaScript-heavy sites where technical SEO problems can hide in plain sight. I recommend it because it does one narrow job extremely well—and sometimes that five-minute check can save you from chasing the completely wrong SEO problem.
Justin Belmont, Founder & CEO, Prose
Verify Googlebot Crawls Through Log Analysis
A great tool to suggest is Screaming Frog’s Log File Analyser — most SEOs are familiar with the crawler; however, only a small percentage take advantage of the analysis tools, where the major insights are. Instead of just trying to guess how a search engine treats a particular website, it shows precisely which pages are crawled by Googlebot and at what intervals using the server logs.
It is really great for us in the case of bigger clients, as it points out crawl budget that is wasted on useless URLs while important pages aren’t crawled at all — issues that wouldn’t be spotted with a regular audit. I advise you to use it, as it effortlessly makes the process of determining what Google knows about a client site move from the theory level to one based on facts.

Check Single-Page Issues With SEO Minion
One lesser-known SEO tool I find especially useful is SEO Minion. It brings several practical checks into one browser extension, which makes it easy to review individual pages without opening multiple tools.
I find that it is one of my best tools to utilize when checking broken links, whether they are redirecting, whether hreflang tags are used correctly, whether your SERP preview is showing properly, and all of the other page-level items you could think of. Using these tools helps identify technical issues that would be easy to overlook while doing a comprehensive website review.
What sets SEO Minion apart from other SEO auditing tools is its focus on individual pages. This means you have the ability to see how your site works at a single URL, notice something wrong with a link, and research the problem right away instead of having to wait for a complete crawl or review of the entire website.
Timothy Clarke, Senior Reputation Manager, Thrive Local
Catch On-Page Gaps With Rank Math
Rank Math is an underrated tool I find useful, but I treat it as a checklist rather than a strategist. It quickly catches basic on-page gaps in titles, metadata, links and keyword placement across recurring content work. The real value comes from pairing those prompts with a human review for usefulness, local proof, buyer intent and conversion. I recommend it because it prevents avoidable mistakes without letting a green score dictate what the audience should read.
Callum Gracie, Founder, Otto Media
Maximize Visibility With GBP Attributes
With over 20 years in integrated marketing and brand strategy, one of the most underutilized local SEO resources I rely on is Google Business Profile’s secondary categories and attributes feature.
While many businesses only pick a primary category, utilizing up to nine secondary categories helps search engines understand your full scope and rank you in the local 3-pack. For example, a cafe that also lists secondary categories like bakery and sandwich shop can capture high-intent discovery searches that competitors miss.
Pairing specific categories with granular attributes and a complete 750-character business description gives you an immediate search advantage. I always recommend auditing these profile features because they maximize your local search real estate without extra cost.
