Use site: Check Google included the reliable?

"Site:" is the most commonly used search engine advanced command to understand how many URLs are included in Google, in order to diagnose some SEO problems, such as to confirm whether to be punished.

More and more people are complaining about the inaccurate return of "site:" recently. Someone reported a sudden drop in the results returned from the site:domain.com command, and no changes in Google webmaster tools, or inconsistencies with Webmaster tool account data.

Some analysts think: more and more people find from "site:" returned strange results. In my opinion, this data is the report can not be trusted. Because a URL is not in the "site:" Results does not mean that not included or is not able to bring the search traffic.

However, although the "site:" is supported in some ways inaccurate data, but we can still clearly see its impact on the actual site rankings: Even if we found that "site:" There may be only 65% credibility, but "site:" The number and search results page traffic is still quite related.

This discussion reminds us that we need to delve into Google's data before we make any summary:

I think the data center controls all the data, which is filtered by Google. Google understands the existence of all pages, but simply chooses more important pages to display in search results. This has been confusing to me until I noticed that a lot of unique keywords/phrases will show pages that don't exist in the results of "site:".

(SEM Watch further explains: Google has a lot of data center (Centers). Even the same search requests each data center may return different results. If you see different data in some data centers, it means that Google is updating the collection. ）

Here are some tools to help you verify the results of Google "site:":
