How the AuthoritySource.ai Site Score Is Calculated
Every publisher site in the AuthoritySource.ai marketplace is assigned a Site Score — a 0–100 quality rating that helps buyers quickly compare placements and helps publishers understand where their site stands.
The score is not a guess. It is a weighted composite of five signals, each chosen to predict how much value a link or brand mention from that site is likely to pass.
The five components
1. Organic visibility (25%)
We measure:
- Estimated organic traffic
- Number of ranking keywords
Both are log-normalized so a site with 10× the traffic does not get 10× the score. A niche site with 5,000 monthly visitors and 1,000 relevant keywords can score very well here.
2. Authority strength (25%)
We measure:
- Domain Rank — DataForSEO's authority rank, scaled to 0–100
- Referring domains count
This reflects the site''s backlink profile and overall authority in the eyes of search engines.
3. Backlink quality (15%)
We look at:
- Dofollow ratio
- Referring-domain diversity
- Spam risk (where available)
A site with backlinks from many different trusted domains scores higher than one relying on a small cluster of links.
4. Content quality (20%)
Our AI classifies each site for:
- Content depth
- Topical consistency
- Freshness
A site that publishes regularly on a tight, well-defined topic scores higher than a scattered, thin-content site.
5. Technical trust (15%)
We check:
- HTTPS
- Accessibility
- Indexability
- No malware or suspicious redirects
The basics matter. A technically sound site protects the buyer''s investment and the publisher''s reputation.
Why log normalization matters
Raw traffic and backlink numbers vary wildly across sites. Without log scaling, a handful of mega-sites would dominate the marketplace and smaller, high-relevance publishers would never get noticed. Log normalization keeps the score fair and competitive across niches.
How the score is used
- Buyers see the Site Score in the marketplace to compare options at a glance.
- Publishers can see the same breakdown in their dashboard and understand which levers will move their score upward.
- The score also feeds into the Match Score, which pairs a buyer''s target URL with the publisher sites most likely to be a natural fit.
A score is a snapshot, not a guarantee
The Site Score is a point-in-time measure based on live metrics from DataForSEO. It is designed to be transparent, repeatable, and directionally accurate — not to predict exact ranking movement.
If you are a publisher and believe your score is missing something, refresh your metrics from your site dashboard and let the data update overnight.
