The basics of exchanging links Principles and strategies
(1) Linking with competitors
From the perspective of major search engines such as Google and Baidu, they not only value "backlinks", but also "backlinks" that are "strongly relevant" in backlinks. ”, we say that the most relevant backlinks are those of our competitors’ websites.
(2) Linking with websites with high PR value Websites with
high PR value (PR≥4) mean high weight and more attention; it is extremely cost-effective to link directly with such websites; it can also be indirectly Get their links: A swaps links with SOHU, and the target website swaps links with A.
(3) Linking with frequently updated websites
Because of the transferable characteristics of "update frequency", spaders can also smoothly crawl our pages while frequently visiting these frequently updated pages.
(4) 10,000 inner page links are better than 1 home page link
From the PR value algorithm, high PR is of course important, but if a particularly large number of web pages (more than 10,000) point to a certain page, it will add up. Although the contribution of each page is not large, due to the large number of pages , the product result is very large!
(5) Natural links have higher weight than pure links.
Natural links refer to links in the text or public relations links. Due to natural links, they generally appear on a page with few external links, and the corresponding weight is much higher than that of pure external links. In addition, a certain amount of keywords can be deployed correspondingly to the corresponding text, so that the relevance can be obtained. Great improvement.
(6) Quality is more important than quantity
Under the same negotiation difficulty, we propose to choose the quality of the connection (i.e. relevance, PR and update). Because an excessive number of "spammy" links will damage our brand to a certain extent.
