What is g-best-seo.com?


g-best-seo.com is a domain name owned by Semalt.com that is used to promote their questionable online SEO services. Semalt employs a blackhat tactic known as referrer spam to make it appear as if a visitor was referred to your website from http://g-best-seo.com/seo2.php. If you look through your website’s Google Analytics data you’ll notice that it looks like a visitor landed on a page on your site with /h/10016924.html in the permalink. However, this is not the case because no one was actually referred to your website from the domain.

If you go to http://g-best-seo.com/ in your browser, you  will be forwarded to a new website that says “get your free website audit now” and “discover your website potential for free.” On this page, there is also a text field where you can submit your website and click a ‘START NOW’  which will take you  to https://semalt.com/?s=http://[search term]&ref=test2 and then forwards you to https://semalt.com/project/[project ID]. Semalt uses these pages to obtain information about you such as your email address, your domain name, and sensitive information from your social media accounts. Once Semalt obtains your email address, you can expect a lot of deceptive and incoherent messages from them.

Semalt has been in the referrer spam for many years and it doesn’t seem like they will ever stop since it’s the only reason people know who they are. Previous domain names you might have seen in your Google Analytics data associated with Semalt include promotion-for99.com9-best-seo.com7-best-seo.com9-reasons-for-seo.com16-reasons-for-seo.com, 17-reasons-for-seo.com, 15-reasons-for-seo.com9g-best-seo.com100-reasons-for-seo.com12-reasons-for-seo.comlocal-seo-for-multiple-locations.comautoseo-b2b-seo-service.comseo-services-wordpress.comseo-services-b2b.comautoseo-wordpress-services.comseo-wordpress-analytics.comseo-for-wordpress.comanalytics-for-seo.comautoseo-trial-for-1.comseo-helper.orgfree-seo-consultation.comget-seo-help.comseo-services-with-results.comfree-seo-help.org, better-seo-promotion.com, and many more. As partially mentioned before, the website uses this spamming technique to dupe people into searching for the website on a search engine such as Google and visiting the website by typing it into the address bar in order to obtain potential customers.

Referrer spam may sound harmless, but it can actually ruin your website’s analytical data and make it difficult to determine your sites real traffic data. The traffic acquired from fake referral traffic can affect most of the data in your Google Analytics reports. For example, the fake referral traffic will show that it lands on a single page on your site and leaves from the same page which creates a 100% bounce rate. If your site is targeted by a lot of referrer spam, you may not be able to identify your website’s actual bounce rate unless you filter the traffic out.
