Backlinks remain one of the top 3 Google ranking factors. Every quality backlink acts as a vote of confidence, telling Google your content is worth ranking.
The hidden problem: 30-40% of backlinks are never indexed by Google. If Google hasn't crawled and indexed the page linking to you, that backlink passes zero value. You could be paying for guest posts that Google doesn't even know exist.
The solution: Check your backlinks regularly, verify they're indexed, and resubmit the ones that aren't. That's exactly what IndexFlow does — check backlinks, verify indexing status, and submit unindexed pages for crawling.
Check if your backlinks are indexed: Use our free Bulk Index Checker to verify which of your backlinks Google actually knows about.
A backlink checker analyzes the external links pointing to a website. It shows you which sites link to a domain, the anchor text used, whether links are dofollow or nofollow, and the authority of each linking domain. This data is essential for SEO link building and competitor analysis.
Backlinks are one of Google's top 3 ranking factors. They act as votes of confidence from other websites. More high-quality backlinks generally means higher rankings. However, not all backlinks are equal — a single link from a DA 70 site can outweigh hundreds of links from DA 5 sites.
Dofollow links pass link equity (also called 'link juice') and directly help improve your rankings. Nofollow links have a rel='nofollow' attribute that tells Google not to pass authority. While nofollow links don't directly boost rankings, they still drive traffic and create a natural-looking link profile.
There's no magic number — it depends on your competition. Check how many backlinks your top competitors have for your target keywords. Focus on quality over quantity: 10 links from authoritative, relevant sites are worth more than 1,000 links from low-quality directories.
This is a critical question most people miss. Studies show 30-40% of backlinks are never indexed by Google, which means they pass zero SEO value. Use IndexFlow's Bulk Index Checker to verify your backlinks are actually in Google's index. If they're not indexed, you can submit them for indexing.
