I am starting my research on eliminating “semalt.com” from an Analytics report. One person suggests putting the following in your .htaccess file.
# block visits from semalt.com
RewriteEngine on
RewriteCond %{HTTP_REFERER} semalt\.com [NC]
RewriteRule .* – [F]
I haven’t tried this yet but I plan on it. The following is a link I started to use. I am sure there will be more to follow.
UPDATE:
I went to Semalt and registered some sites through their tool. I will try to update with the how it worked out.
http://semalt.com/project_crawler.php
I hope this helps someone out there…
