Part 01 · Overview
Welcome
What it is, who it suits, its grades and the ten things to know first
2.0
GPA, above 4 of the 51 other keyword research tools we grade
SERP Gap Analyzer, made by TopicRanker, looks for keywords whose top 10 Google results are weak: thin, outdated, slow or poorly titled pages, or sites with low authority. It also flags your own pages that are slipping in Google Search Console, grades how often AI chat tools mention your brand, and drafts titles, briefs and articles with AI. It is sold as an app in the Semrush App Center.
To get you started, here are 9 things to know about SERP Gap Analyzer, taken from its own pages and our grades.
- 1
Best for finding keywords where the top results are weak
It's sold through the Semrush App Center, so you need a Semrush account.
- 2
Paid plans start at $99 a month
As its pricing page puts it: $99 per month.
- 3
You can try it first
7-day free trial through the Semrush App Center
- 4
It runs on Web
Web.
- 5
Weak-spot keyword reports
Enter a domain and seed topic, with a language and country, and get suggested keywords rated easy, medium or hard, with search volume and the weaknesses of pages ranking now.
- 6
Competitor page checks
Flags ranking pages with keyword words missing from the title, no update in 6+ months, load times over 3 seconds, under 1,000 words or poor readability.
- 7
Optimize Content with Search Console
Connect Google Search Console to find your pages in the top 20 over 90 days that are sinking, or get many impressions but few clicks, and see what to fix.
- 8
A 2.0 GPA, above 4 of 51
That is against the other keyword research tools we grade, on value, the free plan, features, ease of use and platforms.
- 9
Keep it
To replace SERP Gap Analyzer you would be making search volumes for millions of keywords, gathered and kept up to date. That is not a weekend's work, with an AI app builder or without one.

The report card
Best for finding keywords where the top results are weak
SERP Gap Analyzer, from TopicRanker, looks for keywords where the pages ranking now are thin, old, slow or badly titled, and flags your own pages slipping in Search Console. It's sold through the Semrush App Center, so you need a Semrush account. Basic is $99 a month for 10 reports of 6 keywords each, reports take up to 15 minutes, and the maker's own pricing shows tighter limits than Semrush's listing.
| Subject | Grade | Comment |
|---|---|---|
| Value for money | D | Basic is $99 a month, well into this category's dearest tenth, for 10 reports a month with 6 suggested keywords each. Premium is $149 for 30 reports. That's a lot per keyword, even with the AI writing tools thrown in. |
| Free plan and trial | C | No free plan, but a 7-day free trial through the Semrush App Center. You'll need a Semrush account to start it. |
| Features | C | Weak-spot keyword reports, checks on ranking pages' titles, age, speed and length, Search Console fixes for slipping pages, an AI Search Score and GPT-4 drafts. It does its job, but 6 keywords per report on Basic is thin. |
| Ease of use | C | No rating on record. You need a Semrush account, then a domain, seed topic, language and country for each report, and up to 15 minutes' wait for it. |
| Platforms and integrations | B | Web only, inside Semrush, and it connects to Google Search Console to find your pages that are slipping. No desktop or phone app, and no API on record. |
An A is worth 4 points, a B 3, a C 2, a D 1 and an F nothing. The GPA is the average of the five.
Who SERP Gap Analyzer is for
- Fits if your site is small and you want keywords where the current top 10 has weak pages
- Works for Semrush users choosing which slipping pages to update first
Who it is not for
- Pricey if you want lots of keywords, as $99 a month gets 10 reports of 6; Premium is $149 for 30
- Skip it if you don't use Semrush, since it's sold through its App Center
- Not for you if you need results fast, as each report can take up to 15 minutes
- Watch out: TopicRanker's own cards show tighter limits than Semrush's, such as 1 domain and 3 reports on Basic
- Watch out: a scanned domain can't be deleted, only archived, and there's no API on record
Good to know
Good for
- Smaller sites hunting for keywords where the current top results are weak
- Content teams deciding which slipping pages to update first
- Semrush users who want SERP weak-spot analysis inside their account
Worth knowing
- Sold through the Semrush App Center, so it needs a Semrush account; the maker's own site sends trial sign-ups there.
- Basic allows 10 analysis reports a month with 6 suggested keywords each; Premium raises that to 30 reports and 12 keywords for $50 more.
- Each report can take up to 15 minutes, and a scanned domain cannot be deleted, only archived.
- TopicRanker's own pricing cards show tighter limits than the Semrush listing, such as 1 domain and 3 reports a month on Basic.

Keep it, or make your own?
Whether this is something you could build for yourself with an AI app builder, and what you would give up.
Keep it
To replace SERP Gap Analyzer you would be making search volumes for millions of keywords, gathered and kept up to date. That is not a weekend's work, with an AI app builder or without one.
That makes this kind of software worth paying for, not this one in particular: 40 of the 51 other keyword research tools grade higher. It costs $1,188 a year.
What you could make
- Long-form writing: an app builder makes this well.
What you could not
- Search volumes for millions of keywords, gathered and kept up to date.
- A score built from what the top results for each keyword cover.
- The same prompts asked of ChatGPT, Perplexity, Gemini and Google's AI answers every day, and the answers kept.
- AI features, unless you pay a model provider for each request yourself.
What this rests on. SERP Gap Analyzer’s listing: what it does, where it runs, what it plugs into and what it costs. It is a judgement about the kind of software this is. We have not built a replacement for it, and making your own means looking after it too. How we decide, and every tool’s verdict.
