When choosing website space, many people choose those very cheap spaces in order to save the cost of making website groups, which actually brings great hidden dangers to the optimization of website groups, such as using multiple websites under the same IP, which is very slow to open and has great security risks. Such websites are disliked by netizens and search engines! Two: Under the normal choice of spatial IP and domain name, the space of a website should correspond to an independent IP. If you do less than 200 stops, you'd better do so. If there are more than 200 websites, you can put three or four spaces under an IP. In addition, there can be no connection between these three or four websites. Usually, if an IP corresponds to a website space, it will be collected more quickly and the given weights will be compared. For the choice of domain name, it is best to mix old and new. For the choice of old domain names, we must identify the tricky ones, because some domain names have been K, which will affect the weight of domain names and lead to the failure of the whole station group. For SEOER who is engaged in the station group for the first time, it is better to apply for a new domain name, with the highest safety factor! Third, the website content should be updated with original content, but for such a huge group of stations, it is difficult for a single webmaster to have original content, so an appropriate pseudo original is also possible. Don't collect it. If you do this, it will easily lead to failure, and the website weight will not be higher, which will affect the increase of the overall sprocket weight! For huge content, you can hire some full-time network editors to do it!

The most important thing to do a regular website is to improve the user experience, and an important way to improve the user experience is to optimize the internal chain of the website. Usually, articles in a site group have two links, one of which links to another website. Part of it is an internal link pointing to oneself, which is an important reason why the link of another website is a site group, and internal links can effectively improve the crawling of search engine spiders, include more web pages as soon as possible, and add more weight, so the weight of communication will be bigger and bigger! In addition, for the station group, don't be a closed sprocket, there should be a gap, so that the sprocket can be infinitely enlarged and better SEO optimization effect can be achieved! Five: the exchange of friends For the site group, the exchange of friends is naturally a very careful behavior. In principle, the whole station exchange is not recommended. It should be put from the article page properly, because the site group is mainly put in weight, which is a one-way link relationship. If they are linked to each other, they will lose their initial willingness to optimize the site group. Of course, if you find that some of your own websites have certain competitive strength, you can also make common friends, but in the same
