Add the following lines to your /robots.txt file: 
User-agent: SemrushBotSwa
Disallow: /
This instructs SemrushBotSwa not to crawl any path on your site. The Disallow: / directive covers the entire domain including subfolders.

How do I verify if SemrushBotSwa is crawling my site?
Search your web server access logs for the string SemrushBotSwa (case-insensitive grep: grep -i "SemrushBotSwa" /var/log/nginx/access.log). You can also check Google Search Console → Coverage → Crawl Stats for Googlebot variants. For SemrushBotSwa specifically, filter by user-agent in your log analysis tool (GoAccess, AWStats, etc.).
What is the crawl frequency of SemrushBotSwa?

User-agent: SemrushBotSwa
Disallow: /private/
Disallow: /staging/
Allow: /
This allows SemrushBotSwa everywhere except the listed paths. Path matching in robots.txt uses prefix matching — Disallow: /private/ blocks /private/page.html but NOT /public/private/.
Why would I want to block SemrushBotSwa?
There are two main reasons to block SemrushBotSwa: 1. **Competitive intelligence**: Semrush users (your competitors) can analyse your backlink profile, keyword rankings, and site structure. Blocking prevents this. 2. **Crawl budget**: If your site is large, SEO tool crawlers consume crawl bandwidth without contributing to search rankings. Blocking frees up server resources for search engine bots. The trade-off: you also become invisible in Semrush's backlink database, meaning links pointing TO your site from other domains won't appear in competitor reports either.
