How to avoid being banned when selling links

Summary of recommendations for reducing the risk of being banned when selling links on exchanges.
Selling links on exchanges is inextricably linked to the risks of falling out of favor with search engines. A particular threat is posed by Yandex, which has recently diligently taken up the fight against SEO links and all those who use them for promotion and earnings. If your site is dear to you and you would like to keep it safe and sound for as long as possible, then you should take some immutable precautions.:
• Unique content only. Even if you weren't selling links on exchanges, plagiarism could get your resource banned, especially in the early stages. Therefore, it does not matter in what ways, but it is necessary to achieve at least 80-90% uniqueness. You can do rewriting, copywriting, and scanning from paper media, but in no case rely on copy paste.
• Installing the php code. In order not to "shine" once again, it is advisable to avoid the html code of link exchanges. You probably work on the engine, and the hosting supports php, so you don't need to neglect this tool.
• The number of links sold should not exceed the number of pages. At worst, these parameters should be approximately the same, at best they should vary greatly in favor of the latter. In this case, the robots will not have unpleasant suspicions, and it will not occur to them to doubt your honesty.
• There should be more incoming links than outgoing links. Many people should link to your project, otherwise it will seem strange to the search engine that no one notices you, but you publish links to a lot of projects.
• One link per page. When selling links on exchanges, you should be careful and not be greedy. Only on the main page you can afford to put two links instead of one.
• The amount of text on the pages. The link will be safely accepted by search engines if there is a sufficient amount of content on the page that stores it. The average calculation is 1 link per thousand characters. Pages with little text but lots of links and ads are banned extremely quickly.
• You can't sell links from young projects. At first, there is practically no trust on the site, which means that for the slightest fault it can fly out of the index. Don't take any chances, it's advisable to wait six months or a year before selling links on exchanges. By that time, the cost of links will rise slightly.
• Choose themed sites. Try not to work with resources whose subject matter is far from your own. https://elperiodicodeyecla.com/como-se-desarrollan-los-sitios-de-venta-de-skins-de-cs2/
