Seo optimization: establish external connections and establish friendly connections 10 points

1. The relationship between the two websites involved in the link

There is a saying on the network that if the two websites are under the same host IP address or the domain name registration information is the same, the link weight will be reduced. If there is already a link, the link weight is also reduced. The experience of many friends is that if a website is denied or punished by a search engine tutorial, one of the three "if" mentioned above is met, websites connected to are vulnerable to the 9-family connections.

2. Link site weight

That is, the overall weight of the link on the website. Generally, portals> industry websites> professional websites> general websites> corporate websites ...... There is a weight relationship from large to small, so sometimes even if your link is on the portal page, it may be more valuable than the homepage of a common website, and its link is more valuable, the reason is obvious.

3. The PageRank value of the page on which the link is located is PR.

The higher the PR, the more valuable the link is. This is also suitable for keyword ranking. Under the same conditions, sites with high PR may be ranked at the top.

4. Link keywords and descriptions

When linking, you need to use a specific keyword as the link text, or include a keyword in the link text to make the keywords and search words the same or similar. For example, mobile phone and mobile phone network. This is a keyword. You can add a place name or other names, such as Chengdu mobile phone network, Beidou mobile phone, and Yidu mobile phone network.

5. The link exists on the page.

From top to bottom, from left to right, this order is the order of many things, which is also used by many SEO peers in search engine optimization. It is considered that the link weights at the top of the page are higher than those at the bottom.

6. Correlation between the link and the content of the linked website page

Content relevance: this is a very important factor for many search engines to judge the link quality. If the text you link has nothing to do with your website and page content, the weight of the text will be reduced accordingly, this is why many spam messages do not work in this group. The higher the relevance of websites or pages, the higher the link weight quality. This is very important.

7. Text relevance between links and links

This is usually used in soft text promotion and internal website construction. The higher the relevance between the link and the text around the link, the higher the link weight.

8. Connection method

There are many links, such as text links, image links, and JS links ...... Under normal circumstances, the old gods only use text links. If there is an image link, it is purely for the overall appearance of the page. It is best to add ALT text labels when linking images, JS class links are not recommended, which are rarely captured by search engines.

9. Link time

What is the impact of the length of time when a link exists on SEO? Many people cannot understand it. In fact, the reason is very simple. Some search engines are slow in updating your site, especially GOOGLE's update of external links, 3 months. If your external link is less than 3 months old, your link is basically white. If the engine updates your site very quickly and updates it almost every day, the links you have prepared can be captured by the engine quickly. This is of course a good thing, but if you cancel the link after a while, when the search engine is updated again, it finds that the blank space does not exist.

10. nofollow problems

This should not be considered before. When the search engine recognizes the nofollow tag, if www.111cn.net uses this function, the link will not be crawled by the engine, you are not busy with the link.
