Free Backlink Profile Comparator

The Backlink Profile Comparator lets you compare two domains across key backlink metrics — referring domains, total backlinks, dofollow %, DA estimate, and anchor text diversity — to see who has the stronger link profile.

Referring domains count the unique websites that link to you, while total backlinks count every individual inbound link, including multiple links from the same site. One domain that links to you 50 times adds 50 backlinks but only one referring domain. Search engines value referring domains more highly because 200 links from 200 separate sites signal broader trust than 200 links from a single blog roll or footer. That is why this comparator weights referring domains at 25% and total backlinks at 20% in the composite score, and why a domain can win on raw backlink volume yet still trail overall. When you compare two sites here, watch the referring-domains row first — it usually reveals the real authority gap more clearly than total link count does.

Dofollow percentage is the share of a site's links that pass SEO value, or link equity, to the target page. Nofollow, sponsored, and UGC links still bring referral traffic and a natural-looking profile, but they do not directly transfer ranking authority. So between two sites with the same backlink count, the one with a higher dofollow ratio is generally getting more rankings benefit from its links. This comparator weights dofollow percentage at 20% of the Backlink Profile Score and flags which domain wins the row. If your dofollow share trails a competitor, the tool suggests chasing editorial links that are natively dofollow rather than nofollow placements. Enter both sites' dofollow figures to see exactly how much equity gap separates them and where to focus outreach.

There is no fixed number, because the Backlink Profile Score blends five weighted metrics rather than judging referring domains alone. That said, this tool caps the referring-domains contribution at its full 25 points around 1,000 unique linking domains, so gains beyond that point stop moving the score. To win the overall comparison you need a higher weighted total across referring domains, total backlinks, dofollow percentage, DA estimate, and anchor diversity combined — meaning you could trail on link count and still win by leading on quality metrics. After you compare, the tool tells you precisely how many more referring domains you would need to match the competitor on that single row. Load your real figures and the sample data to see how the cap and weighting shape the final result.

Anchor text diversity measures how varied the clickable text of your backlinks is. A healthy profile mixes branded anchors like your company name, generic anchors like "click here," naked URLs, and partial-match keyword phrases. When too many links use the same exact-match keyword anchor, it looks manipulated and can trigger over-optimization penalties, so higher diversity — closer to 100% in this tool — signals a more natural, organically earned profile. The comparator weights anchor diversity at 15% of the score, the smallest of the five metrics, because it is a quality safeguard rather than a raw authority driver. If your diversity trails a competitor, the tool recommends earning links with varied, natural anchors. Enter each site's diversity percentage to see whether either profile leans dangerously on repeated keyword anchors.

Not exactly. The DA Estimate field here is a 0-to-100 authority figure you supply from your own data, modeled on the same Moz-style scale that predicts a domain's relative ability to rank. The tool does not calculate or crawl this value itself — you paste in whatever your link index reports, whether that is Moz Domain Authority, Ahrefs Domain Rating, or SEMrush Authority Score. Because these vendor scores use different scales and link databases, you should compare two domains using the same source for both, so the numbers are apples to apples. DA Estimate carries 20% of the composite Backlink Profile Score. Pull each site's authority figure from one consistent tool, enter both, and the comparator shows the gap and who leads on this metric.
