1-best-seo.com referral

However, if visit http://1-best-seo.com/ you will be forwarded to http://seo2.costcodiaries.com/?site=http:// which is a website that says “get your free website audit now” and “discover your website potential for free.” There is also a field where you can input your website.

Previous domain names you might have seen in your Google Analytics data associated with Semalt include 7-best-seo.com9-reasons-for-seo.com16-reasons-for-seo.com, 17-reasons-for-seo.com, 15-reasons-for-seo.com91-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.

Website owners and other people who monitor Google Analytics data will notice real-time and historical referral traffic coming from 1-best-seo.com mixed in with real analytical data. Most of the time the spam will make it appear as if someone was referred to your website multiple times in order to position the referral traffic data at the top of the accumulated list in your reports.

When a website owner or someone monitoring the data sees a large amount of referral traffic from 1-best-seo.com they might be suspicious as to why someone is visiting their website from a  page on the 1-best-seo.com website. 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.

Although this sort of traffic might sound harmless, referrer spam can actually ruin your website’s analytical data and make it difficult to understand your website’s exact traffic metrics. The traffic acquired from fake referrals can affect most of the data in your GA reports. For example, the fake referrals will appear to land on a single web page on your website and leave from the same website and this will create a 100% bounce rate. If your website is targeted by referrer spammers you may not be able to identify your website’s actual bounce rate unless you filter the traffic out.
