How to make a high quality link? That is, the link weight problem. In the search engine optimization work, the ancient mind has been the link construction as one of the most important factors in the SEO strategy, so a little sense of the link research, combined with some friends on the network to sum up some experience, hope to share with you. Link construction of the external links and internal links two parts, so I will be around the two aspects of SEO links for a simple analysis, so that everyone understand that the impact of the weight of the link factors for the site to better build high-quality links.

1. Linked keywords and their descriptions

Usually when we do the link, we need to use a specific keyword as a link text, or include keywords in the link text, so that keywords and search terms are the same or similar. such as, SEO rankings, SEO optimization, which is the core keywords, can add place names or other names, Zhongshan seo, zhongshan seo rankings, Zhongshan seo services, SEO optimization rankings, SEO ranking services, SEO optimization services such as auxiliary keywords around the core keyword to supplement or explain.

2. Links exist in the page location

From top to bottom, from left to right, this order is a lot of things in the order, this is also a lot of SEO peers used in search engine optimization, that the page above the weight of the link is higher than the weight below, as to the left and the opposite side of the position, which weight higher? The conclusion from our experiment is that the left > right, Search engine is not actually human development, or more in line with the habit of human nature.

3. Link on the page PageRank value is PR

The higher the PR, the more valuable the link is. The same applies to the keyword ranking, under the same conditions, the PR high site may be ranked in a more forward position.

4. Link site weights

That is, link in the site's overall weight problem, usually, Portal > industry website > Professional website > General website > Company website ... There is such a big to small weight relationship, so sometimes even if your link in the portal page, it may be more valuable than the homepage of the ordinary site, its links more valuable, the reason is already obvious.

5. Ways of linking

Links to a lot of ways, text links > Pictures links >js links ... Usually, the ancient mind only do text links, if there is to do the picture link, that is purely for the overall appearance of the page, hehe, do picture link when the best plus alt text label description, do not recommend JS class links, this rarely can be crawled by search engines.

6. Link Time

How long does the link exist affect SEO? Many people do not understand, in fact, the truth is very simple, some search engines for your site update is very slow, especially Google to the external link update, 3 months ah, if your external link time less than 3 months, your link is basically white do. If the engine to your site update quickly, almost daily update, you do a good link can quickly be crawled by the engine, this is a good thing, but if you have a period of time to cancel the link, search engine again to update the time found no, this blank is not very good.

7.nofollow problem

This is not considered before, since the search engine identification nofollow tags, if a site uses this function, the link will not be crawled by the engine, you put the link in this place is white busy.

8. Link and Linked Site page content relevance

Content relevance, this is a number of search engines to evaluate the quality of the link is a very important factor, if you link to the text of your site and the content of the page, then its weight will be reduced, which is why a lot of spam message this group has no effect on the cause. The greater the relevance of the site or page, the higher the quality of the link weight, which is important.

9. Links and links around text dependencies

This is commonly used in the soft text promotion and the construction of the site, the link and link around the text, the higher the link weight.

10. Relationship between two sites implicated in links

The network has such a saying, if two sites in the same host IP, or domain name registration information is the same, the link weight will be reduced, if there have been links, after the link weight will be reduced. For these kinds of sayings is a lot of friends to give the experience, I personally did not realize, but there is a point I can prove: if there is a site by the search engine down the right or punishment, then meet the above three "if" one of the links of the site is vulnerable to Shing.
