Frequently asked questions

How do I check domain authority for free?
Paste up to ten public domains into the bulk Domain Authority checker. It reports Moz-style DA with no login. You do not need Moz or Ahrefs to see a score.
What is domain authority?
Domain authority (DA) is a 1–100 score of how likely a domain is to rank, based on its link profile. It is a comparative metric, not a Google ranking factor. Check yours, then check a competitor on the same tool.
Is there a free backlink checker?
Yes. Paste a URL into the backlink checker Mini App for referring domains and anchors on that one domain. For DA scores on a list of sites, use the bulk Domain Authority checker.
How do I find broken links on my website?
Run the broken link checker on a public URL. It lists dead internal and outbound links so you can fix 404s that waste crawl budget and leak link equity.
How do I get backlinks for a new startup?
Start with directories that pass dofollow links. A Launch Llama listing with our badge on your site earns a dofollow backlink from a DA 73 domain, or reach 20 upvotes.
