1. How important are friendship links? If a website is compared to a city, the friendship link is the way to the city. Its importance is not only that visitors can visit our website by browsing the links of the cooperative websites, but more importantly, it is an important reference for all search engines to find the media of the website and evaluate the importance and value of the website. According to authoritative data, 81% of websites in the world, 71%-91% of their visits come from search engines. Therefore, letting search engines include more pages is the most effective way to increase the number of website visits, and friendly links are an important way to increase the number of included pages. Second, we all know the content relevance of both websites. Each website has its own theme. How can we determine the theme of this website? It's very simple. Look at what keywords are made on the homepage of this website. Each website has a main keyword, which is usually the theme of the website, and the search engine also records the theme of this website in its own relevant database, so this tells our webmaster to try to find a site related to his website to exchange links when exchanging friendly links. Let's give an example. For example, the Red Shirt Online Earning Forum is an online earning site, so when we are in link exchange, we will try to find a site related to online earning. Third, text link or picture link text chain or picture chain? Many people will have their own preferences or according to the needs of websites. If you are linking with big websites such as Sina, Netease and Tencent, you don't have to think about it. Then hurry up and post your LOGO, because the traffic on the homepage of these websites is large and the advantages of LOGO are great, which can bring you considerable traffic. However, the probability of these things happening is generally very small, so let's talk about something practical. If we link with small and medium-sized websites, it is recommended to choose text links, because if the crawling spider distributed by Baidu and Google climbs to the text link website you made, it will continue to crawl to your website page for inclusion through text links, so the more text links, the more spiders there will be, and the more pages will be included. For picture links, you need to wait for a special spider to crawl and include your website, and the effect of inclusion is not very satisfactory. Fourth, the reference basis for exchanging friendship links is 1, PR value, which is a yardstick for Google to measure the importance of a website. It has a level of 1-11. The higher the level, the better the website is. Generally, a website can achieve a PR of 4, which is already a good website. When we exchange friendship links, we should first know the PR value of our own website. Under normal circumstances, don't exchange links with our own PR value websites, or you will be a green leaf of others. Of course, if you are a new station, you must have no choice, and you have to change up bit by bit. 2. Alexa ranking. Alexa is a website that publishes the world ranking of websites. It is an index that is often quoted to evaluate the visits of a website. Generally speaking, websites that rank within one million in the world are passable. If you find that Alexa ranking of a website shows no data, try not to link with such websites. 3. The number of Baidu Google entries. Baidu Google inclusion is an important basis for evaluating the weight of your website. At the same time, the number of entries in search engines should not be too different from the actual content of their websites. Of course, when we are looking for links, we should try to find some websites with a large number of entries. We must not find websites with zero entries from Baidu or Google, because it must have been punished by Baidu or Google. Linking with such websites is harmful to you. 4. Look at the homepage snapshot of the other website. When we exchange friendship links, we usually enter them in Baidu, such as site: to check the number of entries of a website and the snapshot of the home page, and see if the date of the snapshot of the home page is within these three or four days. This is more important. If the content of the home page of a website often does not change or update, then the search engine will not give it too high weight. The most direct performance is that the snapshot date of the home page is late, and some even last month's date. We should avoid link exchange with such sites. We can use some webmaster tools to check the number of exported links on the other website. If we find that there are more than 61 or even 111 external links on the other website, it is not recommended to exchange with him again, because it is of little significance to us. On the contrary, of course, the less the better, and you can also see if the other party's PR is close to you.

hope to adopt.
