How To Block The Semalt Crawler and Stop Getting Spammed


Have you, like so many of us, noticed a slow-down in your site?

Have you then seen a ‘crawler’ in your sites stats?

And – there it is!!

Again and Again and yet Again! is based in the Ukraine. They are trying to justify this spamming by gaining information that will help us all.

Not okay Semalt!

They have a Facebook page and on there you will see they (Nataliya Khachaturyan) states you can just go to their site and request being taken off their list.

This does NOT work. 🙂

Block SEMALT and its Crawler! Stop Being Spammed…

Below you will find a few things you need to do immediately to get them off & out of your sites.


Send a letter like this to


I would like to report for creating a php script that repeatedly hit hundreds of websites multiple times slowing our websites down considerably, like a low-grade DDOS application.

The owner of the website has been contacted multiple times by both myself and many other webmasters and developers and refuses to stop.

**This one may not show any results for you. They actually emailed me back saying they were not moving forward in pursuing the issue. The ones below WILL WORK though!


Send the same information as above to:

Do this for every URL they hit, not just your index or home page.


Go To your htaccess file and add the following code:

RewriteEngine on

RewriteCond %{HTTP_REFERER} semalt\.com [NC]
RewriteRule .* – [F]


If you want to Also RETURN all this negative traffic from their crawler right back to them – add this code to your htaccess file:

RewriteEngine on

# block visitors referred from
RewriteCond %{HTTP_REFERER} semalt\.com [NC]
RewriteRule (.*) [R=403,L]


Do NOT go to their site and submit your URL. This will just give them more information on you.  Some of their links to AVOID are:


You should also tweet about this so others will know and be able to block them also. Use the  hashtags #seo & #semalt. Stop the Spam @semaltcom.


I hope this has helped. Please pass this along to all those you know with websites.
