Hello Friends

I checked the number of my backlinks using an online tool. First day the number was 384. The next day when I checked it was 163. Again on the third day it showed 384. What could be the possible reason for this?

Thanks

Several good points have already been raised by , and . The key thing missing from the replies so far is a short diagnostic checklist and a few less-obvious technical reasons why counts jump up and down.

Possible technical causes:

  • Reporting vs indexing: many services show a sample of discovered links, not a complete index. That makes day-to-day counts noisy.
  • Normalization and deduplication: the same link can be counted once or many times depending on how the tool treats www vs non-www, http vs https, URL parameters, or repeated links on the same domain.
  • Redirects, canonical tags and server responses: links that point through redirects or from pages that return 5xx/403 or are blocked by robots/meta tags can disappear from a crawler’s report.
  • Nofollow, JavaScript links and private pages: links generated by scripts or behind login or marked nofollow will often be missed or ignored.
  • Temporary discovery window: crawlers visit sites on different schedules, so discovery is timing-dependent.

Quick troubleshooting steps:

  • Use verified Search Console and Bing Webmaster Tools for official reports and export the link lists.
  • Export snapshots (weekly) and diff them to see which specific URLs vanished.
  • Fetch a few missing linking pages directly (browser view or curl) to confirm the link still exists and check response codes and redirects.
  • Check server logs for crawler activity and any 4xx/5xx spikes.
  • If the drop is permanent and large, look for manual action messages in Search Console.

Practical advice: pick one reliable source for trend tracking, automate weekly exports, and focus on links that drive traffic or conversions rather than raw counts. Short-term swings are normal; persistent drops need the checks above.

Seems more than likely that the search engine was recalculating things and the low number was when it was still incrementing (adding up the worthwhile backlinks it offers as a sample of what it has discovered, for owner or competitor analysis).

Honestly speaking, there are no accurate tool for calculating backlinks online for every engines using different algorithm. They are only for reference purpose, IMO. So, such fluctuation would be a normal issue. :)

Have a nice day,

I agree with Airforce One, the number of links you have tends to be entirely dependant on which "tool" you are using to check. Unless you have been keeping track manually (and let me tell you from experience that is a nightmare) you are probably never going to know exactly how many back links you have. I would say that in backlink strategies quality far outweighs quantity so try not to get bogged down by the numbers.

I agree. Whenever I compare my backlinks in both Google and Yahoo they are always different...

I guess, may be issue with the software tool which you are using. What is the tool?

I am sure that you will not be disappointed with backlinkwatch.com which I am using so far for many years. It gives me the exact output so far. :)

Constantly Google is updating backlinks periodically. However, just before they do a PR update, chances is the No. of links will move up and down pretty fast in those few days. I would recommend you stick to a more stable tool to check as well, such as SEO Firefox or SEO Quake.
