@cyberjix - many thanks for sharing your story. few questions
[1] anchor ratio: according to semrush, (
https://www.semrush.com/analytics/backlinks/overview/?q=miamiseobitch.com&searchType=domain), "seo miami" has a ratio of 32% and this is sitting at the top of your anchor ratios. "miami seo" has about 2% ratio. what policy do you follow? are you from the old school that says your primary keyword (miami seo) ratio should be in low single digits or you should go over-board with it using a synonym (seo miami)?
[2] Building it up: you said that you build up your pbn. mind saying few tactics that you do for building up your PBNs. What off-page activities do you do?
[3] On-page keyword density: for your primary keyword (miami seo), using microsoft word method, you have a keyword density of about 0.5% and using
https://www.keywordsheaven.com/on-page-tool/ you have about 0.9% of keyword density. Also, using keywordsheaven site, you can see that you have ZERO H1 tag for this keyword, only 2 in <p> tag, and 1 in H2 and h3. On surface, one would say that you are under-optimized; however, you are proving that you can get to #1 position, using your approach. Is this by design? do you follow the same practice for your clients?
[4] PBN maintenance: What maintenance activities do you do on your PBNs? for example, adding new posts once every few months?
[5] PBN adverse effect: assume you have waited 2 months and then you add link from your PBN to your money site. After the link addition, your money site goes down in ranking. You wait another month and no improvement. would you now go back and remove the link from PBN or just add more links from other sources?
