I will increase da , ahrefs DR 50 plus domain authority and tf with zero spam score

My work is manual, and do not worry about spam scores, because spam score only increases when use the broken link. But I always use high-quality backlinks.

I receive all language sites to increase the authority score.

You will receive a detailed report showing the website's authority score before and after.

Domain Rating (DR) is a metric by Ahrefs that measures the strength of a website’s backlink profile based on the quality and quantity of links. It uses a 0–100 logarithmic scale, where higher scores reflect stronger authority and link power. The higher score helps to boost the website's ranking.

Domain Authority (DA) is a ranking metric by Moz that estimates a website’s ability to rank in search results. Scored from 1–100, higher DA reflects stronger authority and helps improve overall visibility and rankings in SERPs.

Majestic TF (Trust Flow) and CF (Citation Flow) are metrics by Majestic. TF shows link quality based on trusted sites, while CF measures link quantity. A balanced TF/CF ratio indicates a strong, natural backlink profile that supports better SEO performance.
