How to Check Backlinks in Bulk

Checking backlinks one domain at a time is fine for a single audit. When you have a list of 50 link prospects, 200 referring domains to evaluate, or a spreadsheet of client sites to review, you need to check them all at once.

Crawly's free bulk backlink checker lets you paste up to 100 domains and returns the referring domain count, total backlink count, and authority score for each one simultaneously. No login required.

When do you need a bulk backlink check?

Link prospecting

You have identified a list of sites you want to approach for a link. Before you spend time on outreach, you want to know which ones are worth pursuing. A bulk check gives you referring domain counts and authority scores for the whole list in one pass, so you can filter and prioritise before writing a single email.

Backlink audit

You have exported your referring domains from Google Search Console, Ahrefs, or Semrush and want to evaluate the quality of each one. Rather than checking them individually, paste the full list into the bulk checker and get a quality overview in seconds.

Competitor analysis

You want to compare your backlink profile against a set of competitors. Paste all the domains, including your own, and see how your referring domain count and authority stack up side by side.

Client reporting

You manage multiple client sites and need a quick monthly snapshot of each domain's backlink profile. A bulk check is the fastest way to pull consistent data across all of them at once.

How to use the bulk backlink checker

1. Go to getcrawly.com/tools/bulk-backlink-checker
2. Paste your list of domains, one per line (no need to include https:// or www)
3. Click check
4. The results table shows referring domains, total backlinks, and authority score for each domain

Results can be sorted by any column. For a deeper view of a specific domain's full backlink profile, including individual referring domains and their quality ratings, use the backlink checker.

What the results mean

Referring domains

The number of unique domains linking to the target. This is the most important metric: 500 links from 500 different sites is far stronger than 500 links from the same site. When comparing two domains with similar backlink counts, the one with more referring domains almost always has the stronger link profile.

Total backlinks

The total number of inbound links, counting multiple links from the same domain separately. A site with 10,000 backlinks from 50 referring domains has a very concentrated link profile, which is weaker than 10,000 backlinks spread across 2,000 referring domains.

Authority score

A 0–100 score reflecting the overall strength of the domain's backlink profile, based on the quality and quantity of sites linking to it. Use this as a quick signal when filtering a prospect list: anything above your threshold is worth a closer look.

Filtering your results

After running a bulk check, the most common next step is filtering. A typical workflow for link prospecting:

1. Run the bulk check across your full prospect list
2. Sort by referring domains, descending
3. Remove anything below your minimum threshold (commonly 30 to 50 referring domains for most niches)
4. Check the authority score for remaining domains
5. Move the filtered list into your outreach tool

This cuts a list of 100 prospects down to a qualified shortlist in a few minutes rather than hours.

Going deeper on specific domains

The bulk checker gives you a summary view. For any domain worth pursuing further, the backlink checker returns the full profile: every referring domain, the number of links each sends, its quality rating, and the outbound link profile.

Use the bulk check to filter and rank. Use the individual checker to investigate the domains that make the cut.

Bulk backlink checking vs a full backlink audit

A bulk check answers one question: how strong is each domain's link profile? A full backlink audit goes further: it evaluates the quality of links pointing to your own site, identifies toxic links that may be harming your rankings, and produces a prioritised list of actions.

For link prospecting and competitive comparison, the bulk check is the right tool. For reviewing your own backlink health, run the full audit process.

Checking authority alongside backlinks

Backlink volume without authority context can be misleading. A site with 10,000 backlinks from low-quality directories is weaker than a site with 500 backlinks from editorial publications.

Crawly's bulk DA checker runs a similar batch check focused specifically on domain authority and spam score. Running both gives you a complete picture: backlink volume from the bulk backlink checker, quality signal from the bulk DA checker.
