Search engines have begun to clean up spam on web2.0 sites. Recently, Baidu webmaster issued the "Web2.0 Anti-Spam Strategy" in order to curb the proliferation of spam, mass messaging, SEO external links and other spam on web2.0 sites. , the web2.0 anti-spam mechanism has gradually taken shape in search engine ranking optimization and it is recommended that website operators participate in anti-spam strategies.
First, let’s talk about the advantages of web2.0 sites: information organization comes from users, and users can interact with each other, forming a development platform for resource sharing. Disadvantages of web2.0 sites: it lowers the technical threshold for users to participate in network information release and exchange, and users can Feel free to create content that interests you, and search engines cannot judge whether it is valuable.
Web 2.0 publishing garbage will generate junk information basically:
1. Open to users. Whether it is current blogs, forums, b2b, classified information, Weibo, or SNS, users are allowed to register to communicate, publish and create content. In other words, web2.0 site information is formed by users' spontaneous organization. Its openness has led to the influx of a large amount of external information, which itself does not require too many programs and website production foundations. The popularization of information construction and user openness have become the source of the proliferation of web2.0 information.
2. Sociability and sociality are important factors in the generation of web2.0 information. Web2.0 is based on user-created content and is an information model generated by relying on the wisdom of the public. The release of information is fundamentally from the user's perspective. Yes, if users create a large amount of worthless content and links, it will also be the source of spam information. Information is aggregated through different users and in different ways, and such information search engines cannot judge whether it is truly valuable information.
Search engines have begun to clean up junk external links. Regarding current web2.0 sites, Baidu search engine observes:
1. The collection of a large number of website contents has been reduced. Among them, the collection and copying of websites are in an unstable state. The collection and copying of website content may face secondary review of the site by search engines.
2. The website’s external links tend to be high and sometimes low. Search engines may judge links from irrelevant sites as low-quality spam links, and this judgment may directly lead to a high loss rate of external links to the website or a reduction in authority.
Shenzhen SEO’s current "web2.0 anti-spam strategy" for Baidu search engine has learned that Baidu presents two trends for content and external links:
1. Websites with authoritative content are more likely to gain trust and ranking from search engines.
2. The role of relevant external links is getting stronger and stronger, and a large number of imported links from relevant sites can improve website keyword rankings. External links with poor relevance will be removed from Baidu related domains, or irrelevant links will not participate in ranking calculations.
3. Based on point 2, if the website lacks domain name diversity and the anchor text lacks diversity when external links fluctuate, it may lead to unstable keyword rankings and is more likely to be demoted by search engines.
