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.

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).
