Reasonable and abundant links are the second factor. Reasonable and effective internal links are equally important as rich external links, and highly relevant and high PR value pages in external links are particularly important. Here are the four principles of backlinks:
1. Definition of backlinks
Backlinks in English are: BackLinks, or Back-Links, also known as incoming links. Backlinks are actually declared inside the target document. In other words, a regular link says "point to document B" in document A, while a backlink says "make document A point to me" in document B. Backlinks are the second element of SEO, and their importance is unquestionable. There are many 10 methods, 66 methods, and 101 methods for increasing backlinks circulating on the Internet. There are also many "black hat" software for group building and group sending, which I won't discuss too much here.
2. Principles of backlinks
1. Time principle
The 2008 new version of the SEO equation SEO=∫Clock=∫C1+L2+K3+O4. The reason why the concept of integral in advanced mathematics is adopted is that the time principle of SEO is very important, especially for the construction of reverse links. .
Increasing backlinks is a long-term accumulation process, which should be done step by step; if an extraordinary number of backlinks are rapidly increased in a short period of time, it will easily be subject to special treatment by search engines (sandbox effect). The SEO effect is counterproductive, and naturally you cannot obtain good search rankings.
2. Quantity principle
On the basis of following the principle of time, the more backlinks the better. As the saying goes, "You may sow widely, but you will reap little." "If you don't accumulate small streams, you won't be able to become a river or a sea." In the vast sea, no matter how hard you work, you will reap something.
3. Quality principle
The quality of backlinks is more important than the quantity for a website to consistently achieve good rankings for a long time. What is a high-quality backlink? The high Pr value and relevance of the link importing page determines the quality of the backlink. For example, if your website is an SEO-related theme, then the incoming links from the top 10 SEO-ranked websites must be of high quality; the incoming links from an SEO-related article must also be of high quality. However, high-quality backlinks are hard to come by. Although one high-quality backlink is worth dozens or even hundreds of spam backlinks, if high-quality backlinks cannot be obtained, , then follow the quantity principle.
4. Position principle
In fact, the position principle is a supplement to the quality principle. Because it is easy to overlook and is as important as the quantity and quality principles, it needs special attention. The so-called position refers to the specific location of the backlink on the incoming link page. When search engines crawl the page, they will give different weights to the content in different areas. Generally, the upper and left areas have higher weights, while the lower (tail) areas have lower weights. Therefore, backlinks appearing in different locations on the import page will have different voting scores. It is recommended that:
(1) If possible, let the backlink appear at the head of the import page
(2) If possible, let the backlink appear on the left side of the import page
(3) None of the above methods are possible, then let your backlinks appear in front of the content area. Backlinks in highly relevant content areas are extremely powerful for search engine rankings! Therefore, pay special attention when writing soft articles. , try to add the "text chain" you need to add at the beginning of the article.
(4) The friendly links at the bottom of the web page are the least valuable spam links, but some are better than none (quantity principle).
