SEO Keyword Analysis Tool
A free web page keyword analyzer: analyze the keywords on any web page, or turn a raw keyword list into a clearer content plan. Group related phrases, spot exact duplicates and review likely search intent before choosing which page to improve.
AI Search Insights
Review Search Console and Bing reports, then map their query or topic rows to any pages included in the files.
Import a report
Choose one report type. Importing replaces the previous rows for that source and leaves other sources as they are.
Export a CSV from the Search Console Generative AI performance report. Page-level files are supported; query details are not assumed if the export does not include them.
When importing multiple files for the same report, use non-overlapping date ranges. Overlapping exports can inflate totals.
No reports imported
Export a CSV from Google Search Console or Bing Webmaster Tools and import it above. The SEO Opportunities tab can review real query impressions and average positions from a Google Web search query export.
A new property may not have report data yet. Wait for actual data; SEOWins will not fill in estimated visibility or rankings.
AI Citation Tracker
Log what you observe when you run the same prompts on AI search platforms. Review linked citations, unlinked mentions and changes over time.
Log an observation
Use a consistent prompt when you compare results. A linked citation means the answer included a clickable source to your tracked site.
No observations yet
Run a prompt on an AI search platform, then log whether your tracked site was linked, mentioned, or not found. Recheck the same prompts later to compare your own sample.
Monthly samples by platform
Counts use only observations matching the filters above. They do not estimate all answers on a platform.

AI Citability Checker
Split a page into passages and see which ones can stand on their own. Get a clear fix for each weak section. This is an editing aid, not a citation prediction.
Query Fan-Out Coverage Tool
Estimate the related searches behind a question, then check which ones your page covers. The searches are AI estimates, not data from Google or ChatGPT.
llms.txt Generator and Validator
Create a draft from your sitemap, edit it, then check the format and every link. You can also paste a file or load the one on your live site.
AI Bot Log Analyzer
See which AI bots visit your site, what they request and which errors they hit. Your log is read in this browser and is never uploaded.
About this tool
Your server logs record what crawlers actually did. Analytics tools usually miss this, because most bots do not run the tracking script. Logs show which AI bots visited, which URLs they asked for, and whether they received your page or an error.
This tool reads Apache and Nginx access logs, plus JSON logs with one entry per line. It groups requests by bot and purpose, so you can separate search crawlers, user-requested visits and training crawlers.
Your log stays on your device. The file is read by JavaScript in your browser and is never uploaded to SEO Wins. Logs can contain IP addresses and private URLs, so that matters.
How to use it
- Download an access log from your host, or export one from your CDN.
- Choose the file or paste log lines into the box. Files ending in .gz are supported in most modern browsers.
- Choose Analyze log. Use Try example lines first if you want to see the output.
- Review requests by bot, the URLs they want most, and any errors they hit.
- Fix useful URLs that return errors, then export the summary as CSV if you want to compare it next month.
What the report shows
- Requests by bot, grouped into search, user visit, training and other.
- Status code counts for each bot, so you can spot wasted requests.
- The number of unique URLs each bot requested.
- The 25 most requested URLs and which bots asked for them.
- The 25 most common error URLs that bots reached.
How to read the results
User-requested bots such as ChatGPT-User and Claude-User are especially interesting, because a person’s question led the bot to your page. Their requests do not show you who asked or what they asked, but the URLs show which pages are being pulled into conversations.
Errors matter most on pages you want to be found. A 404 may point to an old link that needs a redirect. Repeated 403 or 429 responses can mean your firewall or rate limit is refusing a bot. If a bot you want is getting these responses, run the AI Crawler Checker next.
Heavy training crawler activity can be a cost issue on small servers. Check the volume before you decide, and use robots.txt if you want to opt out.
Limits to keep in mind
The report matches user agent text, and anyone can fake a user agent. To confirm a real bot, compare the IP address with the ranges the company publishes. A log also covers only the period and server it came from. If a CDN serves cached pages, your origin server log may miss many requests, so use the CDN’s log where you can.
Frequently asked questions
How can I see which AI bots visit my site?
Download your server access log and open it in this tool. It finds known AI crawlers by their user agents and shows their requests, URLs and status codes.
Is my log file uploaded?
No. The file is processed in your browser. It is not sent to SEO Wins, and it is not saved after you close the page.
Which log formats are supported?
Apache and Nginx combined logs work directly. The tool also reads many JSON log formats, including common Cloudflare field names, when each line is a separate JSON entry.
Why do I not see AI bots in Google Analytics?
Most crawlers do not run analytics scripts, so they rarely appear there. GA4 may show people who clicked through from an AI product, which is a separate thing from bot visits.
Where do I find my access log?
Most hosting panels have a Logs or Raw Access section. On a VPS, Nginx usually writes to /var/log/nginx/ and Apache to /var/log/apache2/ or /var/log/httpd/. Some hosts only keep a few days of logs.
