Help with domain verification?

Question

Search Engine Optimization

Hello. Recently there was such an incident, I bought a domain name, began to develop the site, but after three months the effect was zero, as it turned out due to a shabby domain name (it was under a filter and spammed with links). I
recently acquired a new domain name. It seems like I checked it - everything is clean, but still I doubt it. Can you suggest verification methods or help with verification?
