The site syntax is believed to be a site that every friend who understands seo knows. It can be said to be very common. The site syntax represents checking the inclusion status of the website. for example site:www.sem-home.com 。This is the list of my blog. How many entries will be displayed below, but many seoers find a problem with the number of results on the site. What is displayed below Baidu is different from the actual one. This problemBeijing seoI have also encountered it. This is what Baidu CEO Robin Lee said about this problem.
The original intention of setting the site syntax is actually to expect users to set a restricted search range to achieve more accurate searches. This is essentially the same as intitle, inurl. The number of results under these high-level grammars, like regular searches, is an "estimate" rather than an exact value. Therefore, it is very likely that the "number of results" under the site has decreased, but the actual number of indexes may increase.
What is a more precise method?
1. Monitor traffic from search engines. This is the most direct and essential. If there is no big fluctuation in traffic but the value under the site fluctuates greatly, this can only show the inaccuracy of the site search results.
2. Conduct sample monitoring of the url in the station. Some urls have already been included by search engines, so a collection is taken out and used as the collection status monitoring set; new urls every day that have not been included can also be monitored for their index status. Scripting is easy to write, and this sample-based evaluation is also very effective.
3. Statistical tools provided by search engines. Whether we should provide similar statistical tools is still under evaluation.
