Once you've blocked AhrefsBot in robots.txt (please see instructions), we will stop crawling the site.
Note: This is not immediate, and will take some time for AhrefsBot to read your robots.txt.
You can expect that we will begin to drop blocked pages from the index in about 2 months time.
Note: We will still continue to collect and show links pointing to this site from other domains, since blocking AhrefsBot in robots.txt does not prevent us from indexing backlinks from other websites.
