Search Engine Optimization Links extensive (link popularity) full Raiders

Introduction | links | Search Engine | optimization With the changing of the Internet, the huge capacity of the search engine index update and service is undoubtedly a test. Search engines have also been trying to find innovative ways, such as the relevance of the site based on the breadth of the rankings, to offset the search engine spam trick and malicious control of the page factors of the adverse competition results, to provide users with the most accurate and relevant search results. Today, search engines, such as Google, have been able to provide surfers with an excellent search experience by consolidating the breadth of links into their ranking algorithms.

But that doesn't mean we can be complacent about page factors and site content. The correct understanding should be: for two pages of the same degree of optimization, the content of the same attractive site, in the search engine rankings should be the winner of the high level of links (LP) a higher site. In short, the way in which you can get a very good ranking as long as the page is optimized is no longer feasible. If you want to get your site top position, not only need to optimize the page, but also need to enhance your site's target links to a wide range.


Link breadth vs. link wide scale analysis

The breadth of a site's links refers to the total number of foreign links on the site. Search engines must keep track of these external links for indexing. Not long ago, it was also believed that the breadth of a site's links was determined only by the "number" of external links to that site. That is, the more external links count, the higher the rank.

This is just the first part of the story, search engine software and their developers are not deaf and mute, they have realized that there are many webmasters by false links and other improper means to enhance their ranking purposes. So the search engine abandoned this view of the quantity does not look at the quality of the practice, in turn, the link to the extensive analysis as a judge of the site ranking of one of the parameters.

The so-called Link-wide analysis (hereinafter referred to as "link analysis") refers to the number and quality of links assessment and analysis. The difference between link analysis and the breadth of links is: The breadth of links refers to the number of external import links on a Web site, while link analysis covers both the quantity and quality of external import links. We can see that in the attitude towards the external links of a website, link analysis refers to the number of links in the first place.

Link analysis is a very useful, simple and safe way to determine which page is more relevant to a particular key phrase. This approach accurately determines how others in your industry recognize your site.


Link Quantity vs Link quality

The initial link calculation is based on the number of links, that is, the number of external links in a Web page, the higher the score on the search engine. The principle is as follows:
Suppose a,b two pages. A has 2 external links, and B has 10 external links. Since B has far more external links than a, indicating that more sites point to B, the search engine will assume that page B is more "important" or "authoritative" than page A, that B has a higher voting weight (voting power). Interestingly, because the Web page has the characteristics of all the export links that it assigns to its voting weights evenly, for a and B, the search engine finds that B's export link is more important than a a for a and a for the same number of exported links. In other words, the PR value is high and the number of links to export a few sites to become the ideal link target.

Later, link quality analysis was introduced into the link analysis system, and the link quality and relevance of the first mentioned. Because the search engine thinks: A poor site is almost impossible to get high-quality external links. For the quality of the links, different search engines have different methods of measurement, but the main point is the same-– only those with your target keywords associated with the quality of the site's external links is the ideal link target. Even access to hundreds of low-quality or irrelevant sites is not a link to a high-quality, highly relevant, or complementary site.


Inner chain/import link/export link

Inner Chain (Internal links)
The so-called inner chain, that is, internal links. Refers to the links between pages within the same site. Do not underestimate the inner chain, it is in the entire site, especially for some deep page browsing and retrieval plays a vital role. The role of the internal chain in Google also can not be underestimated, as a site will be its PageRank value passed to its site, the internal link will also be its PR value passed to the linked page. So when you get a higher PR value by creating an external link, if your site's navigation structure is reasonably designed, your other internal pages can also get a certain PR value.

In addition, most search engines are more concerned with the keywords that appear in the link text. Suppose to have a camera photography company, its homepage three inside chain text is: "Wedding Camera", "Enterprise Special Celebration Photography", "Birthday/Shouqing camera". These link words not only clearly understand the linked content, that is, what is the Web page, but also make full use of the Target keyword optimization. However, there are many sites that ignore the optimization of the link text, such as the return of the homepage link only write "Home" two words of the example is not uncommon.

Back chain (backlink)/Import link (inbound links)/Export link (outbound links)
The import link and the back chain (also called the reverse link) the same meaning, refers to the link to your site, that is, we generally say "external links." And when you link to another site, then this site is your "export link." So the export link is you to other sites to provide the site link.

In theory, the link analysis mechanism of search engines only cares about your "import link", that is, how many sites are linked to your site. As to how many sites you have provided to other websites, this is not a concern. So exporting links does not affect rankings. In fact, we find that for your hard "import links", even if they are of equal importance (the PR value is the same), Google is not the same, only those who export less links to the "Import link" to make it a good impression. In Inktomi, a site with an export link has a slightly better ranking than a site with no export links. Why, then? --In the section "Deciding on other factors for link scoring", let's start the discussion again.
