The Google SERP for most commercial queries now has more features than blue links. AI Overview sits above everything. People Also Ask eats the mid-page. A video carousel steals attention on the right. Sitelinks drape off the top-ranking result. By the time someone scrolls to the sixth organic listing — you — they've already clicked somewhere or bounced back to search.
Knowing which features fire for your priority queries changes your strategy. If the feature mix is heavy, rankings alone don't translate to traffic. If the feature mix is light, ranking still moves the needle. Paid tools tell you this. Ahrefs, Semrush, Similarweb — all report SERP features as part of their keyword tracking. But they require subscriptions and they don't always agree with each other.
The SERP Feature Coverage Tracker does one narrow thing, for free: given the HTML of a Google SERP, it detects every feature that fired and lists the hostnames appearing in that SERP. No API, no scraping, no subscription — you paste the SERP HTML yourself.
Why You Paste the HTML Instead of Giving It a Query
Google blocks automated SERP access aggressively. Scraping their results returns CAPTCHAs or empty shells within minutes. Paid SERP APIs exist — SerpAPI, DataForSEO, Bright Data — but they require paid accounts. Free alternatives like scraping Bing or DuckDuckGo produce different SERPs and therefore different answers.
So the tool asks you to do the one thing Google doesn't block: manually run the search in your own browser, view the page source, and paste it in. Takes 45 seconds. No data leaves your browser — the analysis is all client-side.
Open Google in an incognito window. Run your target search. Right-click the page, choose View Page Source. Ctrl/Cmd+A, Ctrl/Cmd+C. Paste into the tool's textarea. Click Detect features.
What It Detects
Fourteen SERP features, each identified by a conservative pattern match against Google's current markup:
AI Overview / Search Generative Experience — the AI-generated summary at the top. Traditional CTR drops 30–60% when this fires.
Featured snippet — the "position zero" answer box. Still valuable, still present on most informational queries.
People Also Ask — the expandable related-question accordion. Direct proxy for what Google thinks matters about this query.
Knowledge Panel — the entity sidebar on the right. Requires Wikipedia/Wikidata presence to compete for.
Video carousel — horizontal strip of video thumbnails. Usually YouTube-dominated.
Image pack — grid of images. Appears for visual queries.
Top stories / News box — news publishers only. Requires Google News publisher status.
Local pack / Map — geo-intent queries. Google Business Profile territory.
Twitter / X carousel — real-time social posts. Appears on freshness-sensitive queries.
Shopping / Product grid — commercial/transactional queries. Requires Merchant Center feed.
Sitelinks — the nested links under the top result. Google earns these for you.
Things to know / Refine — subtopic exploration widget.
Related searches — the bottom-of-page query expansion.
Discussions and forums — Reddit/forum-heavy queries. Google has been leaning on this more.
Each detection is pattern-based. Google ships markup changes periodically, and the patterns need retuning when that happens. If a detection looks wrong for your SERP, the output is easy to spot-check against the actual page.
What the Hostname Analysis Tells You
Alongside feature detection, the tool extracts every outbound URL from the SERP, counts hostnames by frequency, and surfaces the top 30. This is a rough proxy for SERP dominance — sites that appear across multiple features (organic result + sitelinks + AI Overview source + video carousel) count more than sites that appear once.
If you provided your own domain in the optional field, the tool highlights whether your domain is present at all and in which position.
What to Do With the Result
Feature-heavy SERPs (8+ features firing). Blue-link CTR is drastically reduced. Ranking #1 might net you under 15% of search clicks here, because AI Overview, Featured Snippet, and PAA are eating attention above you. Your strategy for these queries: (1) optimize specifically for the features — FAQPage schema for PAA, direct-answer prose for Featured Snippet, schema depth for AI Overview source attribution — (2) keep ranking for the traffic remainder, but don't expect linear returns on ranking moves.
Feature-light SERPs (under 4 features). Traditional SEO still pays. Ranking higher translates almost directly to more clicks. This is where keyword and content work have the clearest ROI.
Mixed — heavy with specific high-CTR features like sitelinks. Sitelinks under the top result mean whoever's ranking #1 is getting outsize CTR because of the expanded real estate. If that's a competitor, your job is to displace them; the sitelinks will transfer.
When to Run It
When you pick a keyword to target. Before you write a single word of content for a target query, run the SERP feature tracker on it. If the feature mix is heavy, the investment calculus changes — you may need content AND schema AND a video AND a PAA strategy, not just content.
When a page moves up in rankings but traffic doesn't. If you clawed from position 8 to position 3 and clicks didn't triple, a feature-heavy SERP is the usual culprit. The tracker tells you how many features are eating your CTR.
Monthly on your top 10 priority queries. Features appear and disappear. An AI Overview that fired three months ago may be gone today; a PAA that wasn't there may now dominate. Quarterly tracking is enough to catch the shifts.
When Google ships a SERP redesign. After any visible Google UI change, re-check your priority queries. The feature mix often changes with the redesign.
Honest Limits
Pattern detection is imperfect. Google changes markup without notice. False positives and false negatives both happen; the patterns here are tuned to err toward false negatives (miss a feature rather than claim one that isn't there).
The hostname count is a raw count of outbound links. Sites with a lot of embedded references (Wikipedia, YouTube) inflate. Treat the top hostnames as "who has presence on this SERP" rather than "who ranks best."
The tool does not track positions or historical CTR. For those, SERP-tracking subscriptions exist and earn their price.
The tool cannot fetch the SERP for you. Paste is the only input path, and that's a deliberate design choice.
How This Fits the Methodology
SERP feature coverage decides whether ranking translates to traffic. The $20 Agency keyword chapter (6) argues for matching intent to SERP shape — this tool measures that shape directly. Chapter 7's FAQ strategy is how you compete for People Also Ask and Featured Snippet when they fire on your target query. For AI-search optimization, $100 Network Chapter 16 (LLM-Optimized Content) is the playbook for the AI Overview era this tool is built to measure. On a new site, $97 Launch Chapter 23 covers how to pick queries whose SERP mix still rewards ranking work — the ones the tracker flags as having fewer than four features.
