If content is the most important element of a website, then links are a close second. Most search engines will check links on the website, including links to other websites, as well as links from other websites to the current website. In order to make better use of links, webmasters began to exchange links on their websites with each other. You add a link to my website on your website, and I add a link to your website on my website.
This has been a great way to promote your website for a long time. You can proactively send an email to a website or company, and then exchange links between the two websites. This benefits both parties and both sites get more links. But don’t overdo it. Soon people began to abuse link exchanges between completely unrelated websites. Regardless of whether the two websites are related or not, links will be exchanged as long as the other party agrees. Some people even create hundreds or thousands of websites in order to improve their website rankings, and then link these websites together.
Search engines also quickly noticed this problem. Search engines notice that someone is artificially manipulating link strategies to improve a site's ranking. As a result, some search engines have added requirements for link exchange in their documentation. The result? If these requirements are not met, the website is likely to be blocked by search engines.
Does this mean that you can't exchange links with other websites? No! It just means that search engines will carefully check the web pages that the links point to. Search engines check the link's relevance to the current page and its usefulness to users who might click on it. If you meet these requirements, you will not be penalized. If you link for the sake of linking, your site will be penalized by search engines or even blocked entirely. Therefore, before exchanging links with other websites, be sure to check the other website's website to ensure that its website is relevant to yours.
