Which question does each tool answer?
Semrush is an all-in-one search marketing suite. CrawlRadar is AI search analytics. The table lists the questions a team usually brings to each, and the tool built for that question.
| The question you are asking | Built for it |
|---|---|
| What are my competitors ranking and advertising for? | Semrush |
| Which keywords should my next campaign target? | Semrush |
| Which AI crawlers fetched my pages this week, verified against vendor IP ranges? | CrawlRadar |
| How many visitors did ChatGPT, Perplexity, Gemini, Claude and Copilot send me? | CrawlRadar |
| Which fix on this page recovers the most points first? | CrawlRadar |
What CrawlRadar measures
- AI crawler visits. A server-side collector identifies 56+ AI crawlers in your request log and verifies each against the vendor’s published IP ranges, because these bots never run an analytics tag.
- AI referral traffic. A tracking tag counts the visitors ChatGPT, Perplexity, Gemini, Claude and Copilot send, and the pages they land on.
- Page readiness. 14 checks score each page 0–100 on whether an answer engine can retrieve, trust and quote it, including the 14 AI crawler tokens in your robots.txt.
How do teams use Semrush and CrawlRadar together?
Plan content and campaigns in Semrush; install CrawlRadar on the site those campaigns point at, so you can see whether AI crawlers fetch the new pages and whether AI assistants start sending visitors to them.
When is Semrush the better choice?
For keyword research, competitive intelligence across search and ads, and agency reporting, Semrush is the broader suite and CrawlRadar is not a substitute.
This page describes Semrush by its category rather than its feature list, because feature lists change. Check Semrush’s own documentation for what it offers today. See the other comparisons for the rest of the tools CrawlRadar is often used alongside.
Frequently asked questions
Does CrawlRadar replace Semrush?
No. Semrush covers keyword research and competitive search marketing. CrawlRadar covers one channel it is built for: what AI crawlers and AI assistants do on your own site.
Why measure AI traffic on my own site instead of in a suite?
Because the evidence lives there. AI crawler visits only appear in your request log, and AI referrals only appear when a visitor lands on your pages, which is where CrawlRadar’s collector and tag sit.
