I use this exchange for permanent links because there is a wide selection here. On some sites, the prices for placing links are significantly inflated, and webmasters exaggerate their metrics for selling, so I have to additionally check their sites using other tools. The project continues to develop, and there is a filter for optimization in Google and Yandex separately for beginners. You can also order multi-level links and crowd links, but I haven't decided to do that yet — I have some doubts, and in my opinion, the prices for them are also too high.
