Often have friends add me qq ask me how to do site optimization, some ask my SEO site optimization knowledge is where to learn, today here may wish to tell you, I have never received SEO site optimization training and theoretical knowledge of learning, regardless of letter and unbelief, the fact is so, because I firmly believe that the practice of truth.

The articles I wrote on my blog are reproduced except in part. The rest of me through the practice of SEO process summed up some of the experience and new, just hope for those and I like SEO novice some suggestions and help, hope to let them go a little detour, perhaps to borrow a precedent is this sentence to describe it.

Let's go to the point, today to talk about external links and keyword ranking of the fierce relationship, then first to understand what external links? As the name suggests, external links, also called backlinks, is from the external site to their own site links. As to query the number of external links can be used to query tools, you can also use query instructions in search engine inquiries, such as Baidu Query external link instruction is domain: Www.wd515.com, in fact, this can not be said to be external links, but the relevant domain, that is, Baidu crawled page appears in your URL is a related domain. Google is link:www.wd515.com, but everyone said Google is not allowed, I have a station for more than a year Google's chain has been only single-digit, and Baidu and Yahoo's back chain has been rising. The other is Yahoo, Yahoo back-chain query instructions are linkdomain:www.wd515.com, Yahoo's reverse chain is updated faster, is also recognized the most accurate, with the results of the query in your site links are in the form of hyperlinks, generally are keyword links.

Since you know how to query the major search engine of the reverse chain, then can also be based on the results of the query analysis of the existence of the chain of the form:

1, Text URL: This kind of reverse chain is usually Baidu can be found, that is, the simple form of the Web site, such as http://blog.wd515.com/youhua/10.html, if you this article was reproduced and did not remove the link, reproduced in the article once Baidu included, You will add a Baidu chain, or you left your URL in the forum, just be Baidu crawl, this is also a Baidu chain.

2, Hyperlink form: This chain can be a keyword link, such as: Shop sourcing, can also be a link to the site, such as http://www.wd515.com (in fact, this kind of reverse chain effect and plain text URL). And the keyword link can be divided into add nofollow and not add two, link nofollow attribute that is prompted search engine do not track meaning.

So what is the impact of the above two kinds of chains on the site rankings? We can query and their peers on the site rankings in Baidu rankings in front of the site, their Baidu reverse chain generally will not be very few, but here is a problem, is not the more Baidu chain more sites ranking the better? It's not absolute, SEO inside is not a word often can hear, content for Wang outside the chain for the emperor, and this chain is usually referring to the keyword import links, and the impact of the Site keyword ranking is an important factor is the number of imported links to the quality of the number, including the addition of nofollow and not add the keyword import links, And the quality is from the high weight of the import link, this can be generally through the exchange of links or purchase links to achieve.

According to the practical observation and analysis, the following conclusions to be verified (to my online 515 supply network for analysis cases):

1, the impact of keyword ranking is the biggest factor in the keyword import links, the weight is not the main factor: my keyword Import link text is generally an online shop source, I spent two months to do this keyword Baidu tenth, Google fourth. Because my friend chain keyword all for this word, the blog message also uses this word, the forum signature also has set the word, inside the chain also has this word. If you want to say that the weight of the site, because I am five months of new stations, and online stores to use less than two months, the weight of how low. And this word is ranked in front of the site than my weight more than half a year old station,

2, Baidu reverse link to the keyword ranking has influence. Since I did not give my site to do outside the chain for nearly one months, Baidu backlinks from 5,000 to 2000, reduced to more than 1900. During the main key words store supply because the keyword outside the chain of support and did not decline, and other keywords such as shop Agent was once from the first to the second page. and Baidu reverse link has increased the word rankings and rise. Therefore, although Baidu backlinks can not affect the ranking of all keywords, but the keyword rankings by the former site Baidu chain will not be very little, for Baidu SEO, Baidu chain is the more natural.

3, keyword Import link instability will lead to keyword rankings, included down. This may cause the website to be regarded as the factor of instability, my own site due to some time ago removed part of the long not update, snapshot lag, the site was down the right of friendship links, resulting in Baidu Google included a reduction, especially Google, from more than 1000 to less than 100.

Why I will say these several conclusions to be verified, because these several conclusions from the website only several, is not representative, therefore in the concrete practice concrete situation concrete treatment. I have always believed that 1000 readers have 1000 hamlet, if you can't write.
