What are the features of SEO external links

Seohttp://www.aliyun.com/zixun/aggregation/8486.html "> External links mainly have the following features:

Relevance anchor text, search engine from the date of birth to make the relevance of the search results of the quality of the important indicators. When the technology is immature, the search engine is the page element to judge the relevance, such as: page title, keywords, description, h tag, bold text and so on.

At that time the webmaster use this search engine loopholes to pile up high heat keyword, resulting in search engine feedback results are spam pages, user experience can not speak. Through this cheating although get a lot of traffic, but this lets the user bored of the Trash page will cause the user to this website, even this search engine's trust reduces, loses the customer, is defeated by the competitor that is normal.

So this look at the page elements to determine the relevance of the method is quickly replaced by the search engine, and then turn to what others say you this site, that is, through the site outside the anchor text links to determine the relevance of the page. For example, your website theme is "Beauty", if there are many beauty related sites Link to your site as anchor text. In particular, some beauty professional nature of the site has such anchor text to your site, the search engine will think that your site is the beauty field of quality sites. Anchor text finally becomes the most important factor to judge page relevance and ranking algorithm. The reason is simple: you flatter yourself, not credible, but many people to flatter you, and even the government officials to flatter you, then you are absolutely really bad.

Second, the weight of the chain page and trust, we put aside the relevance, then the chain ultimately want to be someone else linked to the weight of your site's page and search engine of the site's trust degree. If the high weight of the site, there are a lot of pages linked to your site, then he issued the weight is very high, directly led to the weight of your site domain name, thereby promoting rankings. The weight is actually the search engine to this website Trust degree concrete performance, this besides and the website domain name age, the website scale, the content quality besides also and, this website ability external link related. As long as your site and the high weight of the site has links, then you are judged as the probability of spam site greatly reduced. If your site has Baidu, Google, Yahoo, NetEase, such as large sites issued outside the chain, even if your theme and they do not match, the rankings will still be improved.

Three driven by the rise: The page is included in the site rankings are based on the site is not included in the rankings, a variety of data and SEO experience shows that the number and quality of external links to drive a Web site has a critical impact on the page included. There is no strong outside the chain, if only rely on the internal structure of the site and original content want to drive a large site collection is also difficult. According to previous experience spiders generally only crawl 3-4 layers of links, only very high weight of the site, it is possible to climb to the 6-7-story page, and the external link is also the spider crawl rate of the important determinants, external links more powerful, the spider crawling more diligent, can be more quickly updated content of the site, the high weight of the site, It is common to update snapshots for hours.
