Previously, I bought crowd links on Sape, but I faced indexing issues and started looking for an alternative. In the end, I chose Linkbuilder. What I liked: they publish substantial post texts (the indexing of such pages is better), the keyword fits organically into the text, and there is a guarantee (I haven't seen such a guarantee anywhere else). What I didn't like: it takes a long time to set up the links, there's no option to choose platforms based on parameters, and you can't top up the balance with cryptocurrency.
