Each industry has its own principle of connection and exchange, and everyone knows that the SEO effect brought by friendship links in external link construction is very obvious. A high-quality friendship link is far more effective than hundreds of junk external links. I believe students who follow the Google Chinese Webmaster blog should know that this official Google blog and Zac's SEO blog have exchanged friendship links. At that time, Zac used a secondary directory of his company to create the blog, and the seozac domain was activated at the beginning of 2011. Zac first performed a full-site 301 redirect on the old blog while keeping the space server running normally, thus transferring most of the weight to the new domain! Perhaps for this reason, there was no contact with Google to switch the friendship link to the new domain! Through analysis using the SEOmoz tool, we found that the highest external link weight of Zac's blog belonged to this Google administrator blog!
I've said all this just to prove that friendship links are important in external link construction and hold an important position. Now let's get straight to the point: the specific manifestations of how dangerous it is to exchange links with SEO blogs.
The life cycle of SEO blogs is very short.
Most SEO blogs have a very short life cycle, and there are not many webmasters who can stick with it. For various reasons: they may not have been clear about their positioning from the start, or they may have become exhausted and frustrated focusing too much on rankings. Some cannot see a clear profit model and have switched to making money online, such as Taobao affiliate sites! There are other reasons I won't elaborate on. These phenomena are not just idle talk by Wang Ze; this is my witness during nearly a year as an "SEO blogger." (These are experiences I've had with my friendship links, such as domains not being renewed, switching industries to become scraping spam sites, or even rebranding to medical sites!) Therefore, exchanging links with these types of SEO blogs is not a wise choice!
SEO bloggers are overly sensitive
SEO bloggers are overly sensitive to SEO! For a period of time, the server I used was unstable, occasionally causing issues where the website would be inaccessible for several hours. It was during these few hours that a friend removed my friendship link, leaving me speechless! Should I be happy about their work efficiency? Or should I be upset about their ignorance? In fact, these webmasters are just starting to learn SEO, so they are overly sensitive to it. Reflecting on when I first built my site, I basically didn't exchange friendship links and didn't understand what external linking was! But at that time, I still knew that the term SEO existed, so I made the website title extremely complex, thinking that was SEO. Later, after struggling to find ways to drive traffic to the site, I read N fascinating popular novels and truly understood SEO. In my view, building a website and learning SEO during the operation process is a more natural form of SEO. Conversely, people who build websites to learn SEO (most of them SEO blogs) tend to be more sensitive to SEO and prone to over-optimization! Because they don't produce content, they optimize for optimization's sake! This further increases the risk factor for SEO blog friendship links.
SEO blogs after the洗礼of survival
Every SEO blogger who persists through difficulties has it tough. After the baptism of survival, those who "carefully build their sites" and "build their sites for the long term" stand out clearly! This should be a good thing, but things often have two sides. Because these SEO blogs of a certain quality are liked by everyone, and they are similar type sites, peers start exchanging links with each other! And this easily forms a network cluster unintentionally! A simple example: Site A connects to Site B, which connects to Site C, which then connects back to Site A, etc. Friends interested can analyze "Xiao Jun Blog" and "Hun Xiazi Blog," which have many friendship links, and you'll find many interesting relationship networks. Such relationship networks undoubtedly increase the instability factors of SEO.
Conclusion: The above three points argue that SEO blogs are unstable, SEO bloggers are too restless, and SEO blogs put all their "eggs" in one basket! Therefore, I say: Exchanging friendship links with SEO blogs is a dangerous thing!
