What Are Backlinks?
Backlinks are links from other websites that point to your website. They are one of the most important ranking factors in Google's algorithm. The more high-quality backlinks your site has, the more authority it gains in the eyes of search engines.
Not all backlinks are equal — a link from a high-authority news site carries far more weight than dozens of links from low-quality directories or expired spam domains. Modern search engines assess both the quantity and the editorial quality of incoming links.
How to Use This Tool
- Enter any domain or URL you want to analyze in the field above.
- Click Check to scan the backlink profile of that domain.
- Review the four primary metrics: Domain Authority, Page Rank, Linking Domains, and Total Backlinks.
- Use the detailed report to see global rank and data sources behind the estimate.
For a complete SEO picture, also cross-reference results with our Domain Authority Checker, Page Authority Checker, and Google Index Checker.
How Our Backlink Checker Works
This tool aggregates data from two independent public sources to estimate a domain's link profile without requiring you to register or pay:
- OpenPageRank API — provides the public PageRank score (0–10 scale) and a global rank for the queried domain. These figures derive from a periodically refreshed web graph and reflect the domain's overall authority.
- CommonCrawl index — an open repository of crawled web pages used to count the number of pages indexed from the target domain. This page count is used as an input to estimate the volume of referring domains and total backlinks.
The Domain Authority shown on this page is calculated by FreeGetStats on a 0–10 normalized scale based on the OpenPageRank score, the size of the CommonCrawl footprint, and the global rank position. Linking Domains and Total Backlinks are statistical estimates derived from the same inputs — they approximate the order of magnitude rather than report exact link counts.
Understanding the Metrics
Domain Authority (0–10)
A normalized score representing how strong the domain is in the eyes of search engines. Brand-name sites (google.com, wikipedia.org) sit at 9–10. Healthy small businesses typically land between 2 and 5. A score below 1 usually means the domain is new or has very few references on the open web.
Page Rank
The OpenPageRank score on the classic 0–10 scale. This is conceptually similar to (but independent from) Google's original PageRank algorithm and is widely used in SEO tools as a proxy for link authority.
Linking Domains and Total Backlinks
Estimates of how many unique domains point to the target, and how many individual backlinks exist. These numbers are approximations based on the domain's CommonCrawl footprint, not a direct backlink crawl. Use them to compare relative magnitudes between competitors, not as exact figures.
Global Rank
The position of the domain in OpenPageRank's global ranking of all indexed domains. A lower number means a more popular and authoritative domain.
Frequently Asked Questions
How many backlinks do I need to rank?
There is no fixed number. Quality outweighs quantity: a handful of links from authoritative, topically relevant sites are worth more than hundreds of low-quality links. The right target depends on the competitiveness of your keywords and your industry niche.
Are all backlinks good for SEO?
No. Spammy, irrelevant, or manipulative backlinks can hurt your rankings. Regularly audit your backlink profile and consider disavowing toxic links via Google Search Console.
How can I get more high-quality backlinks?
Create genuinely valuable content (research, tools, original data), guest post on topically relevant publications, build useful resources others want to cite, and engage authentically in your industry community. Avoid paid link networks.
Why are the backlink counts here different from Ahrefs or Semrush?
Commercial tools maintain their own dedicated crawlers and proprietary indexes that are larger than CommonCrawl. Our free estimate uses public sources and is intended for quick, no-signup checks. For exhaustive backlink auditing, paid tools remain the standard.
How often is the data updated?
OpenPageRank refreshes its dataset periodically (typically every few months). CommonCrawl publishes new crawls roughly monthly. The "Last Crawl Index" value in the detailed report shows the timestamp of the most recent CommonCrawl snapshot used.
Is this tool free to use?
Yes. The Backlink Checker is fully free, with no signup, no credit card, and no usage caps for normal browsing. It is supported by ads on the page.
