I believe that friends who have been in contact with SEO have heard the saying "content is king, external links are king", which illustrates the two most important factors of SEO. So, what kind of external links are good external links? In terms of choice, What are the principles?
1. The weight of the external link source page itself. An external link is equivalent to another website voting for its own website, but the score of this vote is different. The score of external links from high-weight pages is relatively high. , which is more beneficial to the ranking of the website. Specifically, it includes the PR of the external link source website, the number of inclusions, whether it is included in the open directory, the age of the domain name and the time when it was first included, and whether the website theme changes frequently, etc. The longer the history and the more stable the website, the better the search index will be. trust.
2. Updates and snapshots of external link source websites. The snapshot of the website page in the search is updated relatively quickly, and the snapshot date is very new, indicating that spiders often visit this page, which means that the link you add can be detected quickly and produce effects. If the snapshot is from a few months ago, it may not be detected for several months after the link is made.
3. The number of export links from the external link source page. The more exported links on a page, the less weight each link will receive. Sometimes when making friend links, you will find that although some websites have a high weight, they have hundreds of export links, and the effect of external links from such pages will not be much better.
4. The relevance of the external link source page to the website content. The more relevant the external link source page is to the content of your own website, the better it will be for the ranking of the website.
5. For the anchor text of the external link, choosing keywords related to the website as the anchor text will be more beneficial to the ranking than irrelevant anchor text. In addition, the text adjacent to the external link anchor text is also a factor that affects the effect of the external link.
6. Generally speaking, the greater the number of external links and the more votes, the more helpful it is for the ranking of the website, except for spam links.
7. The location of external links. Generally speaking, external links appearing in the text are the most natural and best.
8. Which websites the external link source pages point to, whether the content of these other websites is related to your website, and the quality is also an influencing factor.
9. Avoid being considered as spam links. If most of the links to the website come from forum signatures, blog comments, etc., but lack meaningful recommended links in the text or posts, it is also disadvantageous and can easily be considered as spam links. , you may be punished in serious cases.
10. External links from authoritative institutions. Many friends who do optimization believe that external links from domain names with edu to gov suffixes that ordinary people cannot register are better. In fact, according to the official search index law, these domain names are not inherently more important than other domain names. Just because most of the people using these domain names are government and educational institutions, the quality of the website content is generally relatively high and authoritative, and the links from such websites are generally more effective.
