We need to build backlink profile to 11 URLs (for now) for our global gaming website pacogames.com. These URL's are localizated in spanish language and we want to move up at Yandex serp results with 11 associated keywords to these sites. Let's resolve the details on the chat.
I understand that building links is a matter of a few months. Can you as a specialist provide an estimate of how long it may take to get the first position, how much will be the monthly cost including your work? I would like to know the estimated costs of maintaining the first position. How long will these lines be alive (a year or forever?).
We should be interested in long-term cooperation because here we have 50 more URLs where we need to build a link profile.
