Here are four principles for reverse linking:

Definition of Reverse link

Reverse link English is: backlinks, or Back-links, also known as the Import link (incominglinks). A reverse link is actually a declaration within the target document. In other words, the general link is marked "point to Document B" in document A, and the reverse link requires "make document a point to me" in document B. Reverse link is the second element of SEO, the importance of no doubt. Network spread a lot of 10 ways to increase backlinks, 66 methods, 101 methods, there are many groups built, mass "black Hat" software in circulation, here do not do too much discussion.

Second, the principle of the reverse link

1. Time principle

2008 New version of the SEO equation Seo=∫clock=∫c1+l2+k3+o4, the reason for the use of advanced mathematics integration concept, is that the time principle of SEO is very important, especially for the construction of reverse link, especially important.

The increase of backlinks is a long-term accumulation process, to be gradual, step-by-step; If in a short time quickly increased the number of unusual backlinks, it is very easy to be the search engine special treatment (sandbox effect), SEO effect counterproductive, nature can not get good search rankings.

2. Quantity principle

On the basis of adherence to the principle of time, the number of backlinks is naturally more and more. Is the so-called "Alpine", "do not accumulate small flow, no to become Jianghai", the vast network of the sea, a point of harvest.

3. Quality principle

The quality of the backlinks is more important than the quantity of the site, which is consistently getting good rankings. What is high quality backlinks? Link Import page High PR values and dependencies determine the quality of the backlinks. For example, your site is SEO-related topics, then from SEO ranked the top 10 site of the import link must be high-quality; from an SEO-related article Import link must also be of high quality. However, high quality backlinks are not available, although a high quality backlinks are worth dozens of or even hundreds of spam backlinks, but in the case of no high-quality backlinks, follow the principle of quantity.

4. Position principle

In fact, the position principle is a supplement to the principle of quality, because it is easy to ignore and the importance is no less than quantity and quality principle, so special attention. The so-called position refers to the exact location of the reverse link in the Import link page. Search engine Crawl page will give different areas of the content to give different weights, generally, the left region weight high, lower (tail) weight low. Therefore, the reverse link out of the current import page in different locations will have different voting scores, suggested:

(1) If possible, then let the reverse link out of the page now import the head

(2) If possible, let the reverse link out the left side of the import page now

(3) The above method is not possible, then let your backlinks out of the content area of the front, the relevance of high content area before the test of the reverse link to search engine rankings extremely powerful! Therefore, write soft text special attention, in the beginning of the article to add as much as you need to join the "text chain."

(4) The link at the bottom of the Web page is the most worthless junk link, but there is always better than no strong (quantitative principle).
