What is SERankingBacklinksBot?
SE Ranking says this bot maps links between public web pages for its backlink data. It documents this exact user-agent, says the crawler follows robots.txt and uses a default three-second crawl delay when no other delay is set. The company publishes bot IP ranges and a reverse-DNS check to distinguish its traffic from a spoofed user-agent.

How to Control SERankingBacklinksBot
Block Completely
To prevent SERankingBacklinksBot from accessing your entire website, add this to your robots.txt file:
User-agent: SERankingBacklinksBot
Disallow: /
Block Specific Directories
To restrict access to certain parts of your site while allowing others:
User-agent: SERankingBacklinksBot
Disallow: /admin/
Disallow: /private/
Disallow: /wp-admin/
Allow: /public/
Set Crawl Delay
To slow down the crawl rate (note: not all bots respect this directive):
User-agent: SERankingBacklinksBot
Crawl-delay: 10
How to Verify SERankingBacklinksBot
Verification Method:
Check the source IP against SE Ranking's published backlinks-bot IP list or confirm reverse DNS under seranking.com; the user-agent can be spoofed.
