    This is what Webroot says about Semalt. com:
    "This website has been reported as unsafe
    http://semalt .com/

    We recommend that you don't continue to this website because it is reported to contain the following threats:

    Malicious software threat:
    This site might contain links to viruses or other software programs that can reveal personal information stored or typed on your computer to malicious persons."
    That seems based only on reports made.

    I was able to access this site before they had the register and login screen.
    All I saw was one big long list of websites.
    I reckon it is a site used to harvest addresses for attacks. Seems that after a hit from a link on this site there can be a number of meaningless hits from the Ukraine and failed login attempts.

    This site continually shows up with a significant number of click throughs on google analytics. How can it be blocked? This really takes away a lot of the implact of google analytics.

      You could probably add a filter to block them from the reports.

    Hello, seems they've put up a page to request removal from their crawlers.
    http://semalt .com/project_crawler.php
    .htaccess does this invisibly to them if that's your choice:
    # block visitors referred from
    RewriteEngine on
    RewriteCond %{HTTP_REFERER} semalt\.com [NC]
    RewriteRule .* - [F]
    Source -
    However on some of my domains I don't have that option so didn't have that option.

      What a relief, just submitted my site for removal. I will let you know if it doesn't work. Thanks for sharing this!

    I noticed this at the same time I had 1200 hits from tel Aviv on a blog that normally gets 10 hits a day. Needless to say I'd like to block them but how do I do this with blogspot?

    • Anonymous: 1 month, 0 week ago

      Did anyone get back to you about getting it blocked from your blogspot? I'm having a lot of traffic saying they came through this semalt site.

  • Anonymous: 1 month, 1 week ago

    I have seen this site related with hijacking of the browser that redirect the traffic to numerous sites of spam. That test was done with Chrome under Windows. I don't know if in GNU/Linux is different, I will try with a Live CD of Ubuntu.

    The problem almost stopped by putting semalt .com appointing to localhost

    I am getting referrals traffic from this website, and all the visits from this website are having 100% bounce rate, how can I get rid of this website???? its kind of threat to my website's online reputation. Feels like someone is spying on my website. How do I BLOCK THEM?

    Looks bogus to me, in my google analytics the bounce rate for traffic coming in from this site is 100% !!!

  • Anonymous: 1 month, 2 weeks ago

    The service is fake. If I check the IPs where I get the referer from semalt .com it is 90% from South America but we are a German website.

    As a webadmin I have very bad experience with Ukraine Internet. A lot of harvesters hackers and bots.

    If you want to block semalt .com from visiting your site and making havoc with your statistics add this to the end of your .htaccess file….

    Semalt LLC is the Europe-based company established in September 2013. The corporate headquarters is located in Kyiv, Ukraine. Semalt LLC is a web service and software developer aimed at creating a high-quality cutting-edge and available SEO and marketing analytics tool.

  • Anonymous: 1 month, 2 weeks ago

    My sense is that this is a misguided marketing/publicity stunt on the part of Semalt. I've read statements from them and they don't really seem to have it together, though they sound like a legitimate company.

  • Anonymous: 1 month, 3 weeks ago

    They latched onto my site in Europe roughly 4 days ago (Feb.26) and account for 60% of my views on a daily basis.

    Can anything be done to report these people? My preference would be to have them eliminated.

  • Anonymous: 1 month, 3 weeks ago

    These guys were bringing my bouncing rate up with their crawler. What I did was to add the following htaccess instruction:

    RewriteEngine on
    RewriteCond %{HTTP_REFERER} ^http(s)?://(www\.)?*$ [NC]
    RewriteRule .* [L]

    What it does it's to redirect it to It seems to be working fine because I don't have 1 single crawler.php visit since I've add this.

    Hope it works out for you guys too!

    • Anonymous: 3 weeks, 6 days ago

      We should all set it so it redirect to semalt .com not google

    • Anonymous: 1 month, 1 week ago

      How would this approach work with a wpengine install? Not sure if the wpengine part is relevant but my htaccess file already has the following...

      # BEGIN WordPress

      RewriteEngine On
      RewriteBase /
      RewriteRule ^index\.php$ - [L]
      RewriteCond %{REQUEST_FILENAME} !-f
      RewriteCond %{REQUEST_FILENAME} !-d
      RewriteRule . /index.php [L]

      # END WordPress

      Would I add it to the end or overwrite what's already there?

    • Anonymous: 1 month, 2 weeks ago

      This is by far the best approach. Stops them cold.

      I was getting half a dozen "visits" from them logged per day all from different IPs in Brazil. Then they started coming at an increasing rate from all over. It is strictly a marketing effort hoping we will notice, follow the link and perhaps sign up for their service. Since their very marketing effort distorts the analytics they want to sell us I can't imagine they are anything but a scam. Block them!

  • Anonymous: 1 month, 4 weeks ago

    We have block them so many times but each time the addresses are from different countries - who do we report them to Google ?

    • Anonymous: 2 weeks, 2 days ago

      Maybe you forgot to specified the subdomains of your sites as well, because the system identifies a subdomain as a separate site. Otherwise the crawlers will continue visiting your webpages.

    semalt have been hitting a lot of my sites recently so I decided to block them in my .htaccess I didn't use the IP as some have in this thread rather (I assume their IPs will change)I have blocked by referrer semalt .com

  • Anonymous: 2 months, 1 week ago

    I tried to log in but nothing happened, other than submitting a username and password, but now I found someone from Colombia, and two others from Brazil accessing my site.... The source of the visits was Suspicious?

    Meanhile, related or unrelated, my computer crashed!

    How did they know my site if I did not proceed beyond the failed attempted registry?

  • Anonymous: 2 months, 1 week ago

    This show's up in my stats daily.
    It's originating from this IP: Which is assigned to brasiltelecom .net .br

    The BIG problem with blocking unwanted bots etc etc on IP's or IP block ranges, it doesn't work if the IP or block changes. If your have hassles with semalt .com and other misbehaving bots, script kiddies and anything other suspect entities crawling your site, go check out zbblock. It's a free script which blocks all the cr#p at the front door, even before it sucks down anything. Your site must be php driven for this to work.

    I've been using it since Oct 2013 and it stops Baidu and other such pests in their tracks.

    I'm getting hit by this site constantly and in addition I am getting hits from many South American countries that has NO interest in what I do. I suspect it is all related to this semalt site. Too many IP's to block so I hope they simply go away.

  • Anonymous: 2 months, 2 weeks ago

    I get the semalt/competitor-analysis links too on blog stats. Foolish me, went to and got a logon or register page. filled out an email made up a password and got to a keyword tool that said it provided a free 7 day file. Tried a scan and it just churned without progress. I think it needs to be reported and filtered somewhere and saw a possible method reading further down in these comments.

    Viral/guerilla marketing using Bots and 'Black hat' techniques, trying to get you to pay for what you can get elsewhere for free. I wouldn't even touch this site with someone else's 9ft pole it's that dodgy. Just don't. :(

  • Anonymous: 2 months, 3 weeks ago

    Also showing up drastically in my results, first noticed it being 2nd to google as a referrer. My gut instinct is that they are manipulating it so they appear so high and people visit out of curiosity and maybe decided to use the service...which isn't explained. Completely shady way of a company to go about gaining customers. Why would I use a service that manipulates my visits to get an accurate picture of my web traffic?

  • Anonymous: 2 months, 3 weeks ago

    Same here... I found them listed on my analytics report as a website linking to our website... sending us 70% more visits ? .... not sure if they are legit.

    I saw it for the first time as a source for visits to my blog. No idea why. I've never registered with them, nor have I ever been contacted by them in any way. Biggest visitor to my blog though.

    I have been seeing SeMalt as a referrer on my blog. Referring people from Brazil, Argentina, Peru.... and then my wordpress account name.

    Thank you.

    According to one person Semalt is a Botnet, and this is the best explanation for the combination of shady practices and multiple IPs:

    Darren January 22, 2014 at 6:45 pm #

    Semalt are using a botnet (that’s innocent people’s computers which have been infected with a virus) to spam thousands of blogs with fake referrer spam. These visits are aimed at those webmaster who publish a list of top referrers on their homepage but the they are targeting sites indiscriminately.

    The response from Semalt you have published in good faith is not true.


    JDriver January 23, 2014 at 6:34 pm #

    I’ve just had a load of bot hits from Semalt myself, messing up my stats. Their technique of trying to gain hits seems to be against Google’s guidelines so I’ve reported them for Black Hat techniques. I urge others to do the same. Click here to report them.

    I also get this site in my analytics regularly. It seems someone has set up a monitor to watch my site as it says in the url.

  • Anonymous: 3 months, 0 week ago

    I found using this stops hits in your stats:

    <?php if ( !preg_match('/semalt\.com/', $_SERVER['HTTP_REFERER']) ) { ?> // your stat code goes here <?php } ?>?

    • Anonymous: 1 month, 1 week ago

      Assumably this isn't the best approach for a heavily cached site though? You wouldn't want semalt triggering the cache then following visits would skip the tracking code

      does this stop the site hiting you or it only excludes the stats?

    It is a phishing and spamming site. Do not click on their links they are sending. You will be bombarded with false traffic.

  • Anonymous: 3 months, 2 weeks ago

    It's not a phishing attempt, it's actually a very good usability feature that allows you to login if you already have an account, or create an account if you don't have one with the one form. Just enter your email address and a desired password, then press register/login and you will be prompted for your name, after which you will be logged in. Very easy.

    I noticed a bunch of referrals from this domain too, it's possible that my competitors are using this tool and finding my domain, which then gets sent as a referrer.

    It's also possible that they are simply spamming their URL as a referrer to pages all over the internet. Many other tools targetting webmasters have used this tactic in the past, and many more will use it in the future. Us webmasters are always checking our logs and when we see a new referrer, especially one sending as much traffic as, we are naturally curious and go check it out.

    I wouldn't say the site is sinister, unless you believe that SEO is sinister, in which case you probably don't know much about SEO.

    • Anonymous: 2 months, 3 weeks ago

      Oh and the name is supposed to be "SeMalt".

      "Semalt will go to your site, and will in turn show up on sites that are referring traffic to your website. This then gets you curious, and click on their website, and BOOM now they have your information. The site is beyond shady, and I would not trust them with your information.

      No one knows what they actually do, if they do anything at all… Avoid at all costs"

      That's all good and well, but how would you know you wanted to have an account? The website isn't advertising to the public. It's login page set up implies it's a private venture. Again, fine, but it doesn't inspire confidence or trust. Leading one to wonder why you're advising people to take a leap of faith and give them their email address?

      The last sentence is a bit condescending. As many people have noted visitors come from many countries that would have no reason to go to their sites. These visitors are probably using a proxy service. In fact I assumed semalt was a proxy service based on traffic logs until I found this thread. There's one visitor who uses Google Chrome/Win 7 on a laptop who has browsed from Ecuador, Brazil and Italy. It's not a proxy default because someone else using the service was in Brazil using IE 10/Win 8.

      Several things are going on at the same time. While it's obviously not a phish, it's still odd traffic behavior. It looks like a service set up by a private group. They also own .net and .org, same registration dates, whois proxy, etc.
