Short answer: different query formats and search‑engine behavior produce different (and incomplete) backlink results. Including the protocol or the full host narrows the match; engines also normalize URLs (www vs non‑www) and apply internal filters, so one query can show more hits than another. This is what was pointing out, and it matches ’s observation that Google, Yahoo and Bing can behave differently.

Public search operators are not a reliable backlink inventory. Search results were never meant to expose a site's complete link graph, and engines often limit or sample what they return. is correct to warn about accuracy. For authoritative backlink data use each engine’s webmaster tools (verify the property and check the Links/Backlinks report) rather than ad‑hoc queries. Google Search Console and Bing Webmaster Tools are the primary sources:

For a wider picture use multiple third‑party link indexes (each has different crawl coverage): Moz, Ahrefs, Majestic or free tools like OpenLinkProfiler. Expect different counts from each service; they complement, not replace, the webmaster tools. See Moz and Ahrefs for how third‑party crawlers differ:

Quick practical checks and fixes:

  • Verify which hostname your site canonicalizes to (www vs non‑www) and use a single canonical with 301 redirects.
  • Ensure linking pages are crawlable (not blocked by robots.txt or meta noindex).
  • Check server headers / redirects locally:
    curl -I -L http://yourdomain.example

    Combine Search Console/Bing data, third‑party indexes and server logs/analytics to build a complete picture. That approach avoids over‑reliance on fragile search operators and explains the discrepancies you’re seeing.

I suspect it is because when you use the http:// or even the www. it forces the search engine to only check for backlinks containing that prefix. So if for example the backlink did not contain the full http:// in the url then it would not show up in the results for your first search term. So for that reason you are not going to get very reliable results with your second search term and will only get reliable results with your first search term which is the following:

www.arif-4121f.info -link:www.arif-4121f.info

I don't think any search in finding backlinks to a site would be not accurate for no search engines would return all backlinks for a site. I only seoquake add-on for Firefox for this purpose. :)

I see it's your first post so welcome to daniweb and as for the question, you will get a better response if you start a new topic in the Java forum. Currently you have posted in the Search Engine section and very few people who browse this category will know the answer to a Java question unlike those who browse the Java section. So to begin using daniweb, go to the Java section then click the big button that says start new topic and fill in the details. Then the community will see how they can help you.

In my opinion, in most search engines they tend to index sites with . rather than http:// only in front of the domain names. I think the reason behind this is that the formal format of complete domain name is with the plus the domain name and extension name. right? Correct me if I'm wrong. This only my analysis of the situation.
