In begin sorry for my bad english.If you understand any parts this post please tell me. I have the following problem, I have a page optimized in speed insight 99/100 and 99/100 for pc cells. Adapted by RWD. Subpage has a unique content, is well hyperlinked, however, it does not appear in Google's index. There has also banned after searching site: domainname.co - is visible. Seoptimer does not show any errors. Page loads of less than 2 seconds. I would add that the sub has been at least a month. Page can be seen in google but only for a moment, just when added to through the "Check as google" in the GSC - then sub is visible on the phrase that interests me but on the 200+ positions, but quickly disappears, then again, is not visible until the second addition.
