SEO is inseparable from the construction of external links. Many people even regard SEO as a big competition in the number of external links, so link sales, forum signature sales and other money-making methods based on external link construction are born. It is undeniable that this method It can indeed bring a large number of external links in a short period of time, which will play a significant role in increasing the number of external links and increasing the PR value. However, the disadvantages of purchasing links are also obvious. Once renewal is stopped, the number of external links will immediately drop, which can easily be detected by search engines and punished.
Doing SEO is a long-term systematic project. As mentioned before, time is the best SEO. Therefore, it can be said that doing SEO is about patience and persistence. It is not about coming to Baidu to know, various forums, and blogs today. The most taboo thing for search engines is to send out external links violently and then leave them alone. The most taboo thing for search engines is the intermittent and concentrated increase in external links in batches, which is very likely to be punished. Let me tell you here, this amount is relative to the base of your website. If you add twenty or thirty external links to a new website a day, you may be punished. However, for Sina and Sohu, it is normal to add tens of thousands of external links a day. within the range.
Having said so much before, I can sum it up in two words: naturally, everything you do must conform to the identity of the website. When adding external links, start from the human way of thinking (after all, search engines are developing more and more in the direction of humanization), consider what seems reasonable, and minimize the traces of SEO to obtain good rankings. It will be a matter of course.
