DR Compare

What Is DR Compare?

DR Compare puts two websites side by side on Ahrefs Domain Rating, the 0-100 score for backlink-profile strength. You enter your site and a competitor, and the tool shows both scores with plain-language bands, names the leader, and states the point gap. Because DR is logarithmic, the note also reminds you that each point near the top costs far more links than each point near the bottom.

Both lookups share the same 24-hour cache as the single and bulk checkers, so comparing the same pair twice answers instantly. Unscored domains show an honest message instead of a fake number, and the verdict only appears when both sides have real scores.

What This Tool Can Do

• Score two domains at once with live Ahrefs DR numbers.
• Show both scores side by side with plain-language bands.
• Name the leader and the exact point gap, or call a tie level.
• Explain the logarithmic scale so gaps read correctly.
• Reuse cached scores so repeat comparisons are instant.
• Handle unscored domains honestly: if either side cannot be scored, show one clear message instead of a guessed winner.
• Run with no signup and per-visitor fair-use limits.

Why Compare Instead of Checking Solo

A lone DR number means little without context. DR 30 sounds modest until the sites outranking you sit at 22; it sounds strong until they sit at 65. Head-to-head comparison turns an abstract score into a concrete gap: how many points behind, roughly how much link building that implies, and whether the fight is months or years. That gap belongs in every competitive brief and every realistic SEO timeline.

Who This Tool Is For

• Founders sizing up entrenched competitors before entering a keyword fight.
• SEO consultants opening audits with a visual gap clients instantly grasp.
• Content teams deciding whether a topic needs links or just better content.
• Bloggers tracking the gap to the next site above them over time.
• Buyers comparing two acquisition targets on authority before deeper diligence.

How to Use This Tool

1. Type your site on the left and the competitor on the right. Full URLs work; paths are stripped.
2. Press Compare and read both scores with their bands.
3. Read the verdict line: who leads and by how many points, or a level tie.
4. Interpret the gap logarithmically: a 10-point gap at DR 60 dwarfs a 10-point gap at DR 20.
5. Record the pair and revisit monthly to see whether your link building closes the gap.
6. Rotate through several competitors to map the full authority ladder in your niche.

Reading the Gap at Different Scale Ends

The same point gap means different work depending on where it sits. A 10-point gap between DR 15 and DR 25 can close with a handful of decent directory links, guest posts, and launch coverage over a few months. The same 10 points between DR 60 and DR 70 can take a year of sustained digital PR, because every point needs exponentially more and stronger referring domains. Small sites should therefore attack gaps below DR 40 first, where effort converts fastest, and treat gaps above DR 60 as long campaigns with quarterly milestones. When the gap exceeds 30 points, consider outflanking on relevance and intent rather than outscoring on raw authority.

Limitations You Should Know

Two domains is the whole scope; for full landscapes use the bulk checker. DR ignores relevance, traffic, and page-level strength, so a lower-DR specialist often outranks a higher-DR generalist on its home topics. Scores cache for a day and move slowly anyway, making daily comparisons noise. When one side has no score the tool says so plainly and skips the verdict rather than guessing.

Turning the Gap Into a Link Budget

A point gap becomes actionable when converted into links and money. Estimate how many referring domains sit behind each point at your scale end: a handful near DR 20, dozens near DR 40, hundreds near DR 60. Multiply by your cost per placement from past campaigns, whether that cost is outreach hours, content fees, or digital PR retainers. The result is a rough budget to close the gap, which either justifies the campaign or redirects it toward keywords where the gap is cheaper. Revisit the maths quarterly, because both sides keep building and the price of a point rises as you climb. Track spend per point alongside the gap so future budgets rest on your own data.

What to Do and What Not to Do

Do compare against the sites actually outranking your target pages, not famous giants in other niches. Do log gaps with dates to prove progress to stakeholders. Do pair the authority gap with a content and relevance audit before budgeting links.

Do not panic over small gaps; a few points at the low end close with a handful of decent links. Do not assume a lead guarantees rankings; intent match and content depth still decide clicks. Do not compare unrelated sites for fun and draw strategy conclusions from it.

When the Comparison Fails

The verdict needs a real score on both sides. If either domain cannot be scored, the whole comparison stops and the page shows a single message: "Could not score both domains. Check the names and try again." Neither score is shown in that case, even if one of the two lookups worked, so the message does not tell you which side failed. The usual causes are:

• An invalid entry on one side. IP addresses, single-word host names, names with underscores or spaces, and non-Latin domain names typed in their native script are all rejected. Use the xn-- punycode form for an internationalised domain.
• A domain with no score. Very new or obscure sites may have no rating in the data source yet.
• A slow or busy data source. A lookup that takes longer than 15 seconds, or one the source turns away, fails. After a refusal, that domain is paused for 10 minutes before it is tried again.

To find the side that failed, check each domain on its own in the single Domain Rating Checker, which reports the exact reason. Any side that did score is kept in the 24-hour cache, so when you press Compare again only the missing side is looked up.

How the Two Inputs Are Matched

Each box is reduced to a bare host before the lookup: lowercase, with the scheme, path, query and port removed and a leading www. dropped. Other subdomains are not merged into the main domain, so blog.competitor.com and competitor.com are scored separately. Compare like with like: if your blog lives on a subdomain and the competitor's lives on the main domain, the two numbers do not describe equivalent things. Entering the same site in both boxes, for example once with and once without www., simply gives a level result.

Rounding in the Verdict

Scores from the data source can carry decimals. The two big numbers are each rounded to whole points, and the gap in the verdict line is the rounded difference of the exact values. That can produce results that look slightly off:

• Scores of 45.4 and 40.6 display as 45 and 41, yet the verdict says the first site "is ahead by 5 points", because the exact gap is 4.8.
• Scores of 45.2 and 44.9 both display as 45, yet the verdict names a leader "ahead by 0 points". "Level on Domain Rating." appears only when the two exact scores are identical.

Treat a gap of one point or less as a tie. Differences that small are inside the normal week-to-week movement of the score and say nothing useful about which site is stronger.

One practical note on the form: the boxes do not react to the Enter key, so press the Compare button to run the check.
