You are worrying about nothing. There is nothing suspicious about bots crawling your website. Pay attention – bots of various resources including Semalt must be displayed in your statistics. You wouldn’t mind your blog being indexed by search systems unless webpages are hidden from indexing.In any case we believe that every webmaster aims at improving website traffic. For this end it is necessary for the website to get into a search engine index. This is the major reason we do not recommend hiding webpages from bots.As for Semalt, it is a perfect detector of qualitative websites. Semalt indexes only qualitative webpages determined as competitors to our customers. If a website makes a list of competitors for a project, it means that its internal optimization is done properly. Now it is time external optimization was addressed, and soon your blog will be able to earn leading positions on Google.
