Interesting SEO knowledge that the search engine officials won't mention

　　I. Handling of prohibited words

Baidu deal with prohibited words is only to deal with the word itself, that is, the rookie search "x Liu", "x Liu Address" can not search the sacred Web page, but it is possible to search:

X Liu Address.

See the search results can also point snapshots, eliminating the pain of Google.

　　Second, open platform

For Baidu's data open platform, its display form most of the time and ordinary Web page is not the same, but there is no special style. The following figure 58 of the same city moving category, that is, open platform, more than the ranking of ordinary pages preferred.

So to distinguish a search results is not Baidu open platform, can not only look at the display style of the page, but also to see the serp HTML source code.

In the following figure, the corresponding table for each search result, whose class is Result-op (open), is the result of an open platform. (Use Firefox or Chrome's "review element" feature to view)

In addition, Baidu products in the same display form, some of the open platform, there are some and open platform independent, which also need to be result-op to distinguish.

　　

　Third, advanced search syntax

Domain is not used to check out the chain of Baidu, the most simple to search this can be known: Domain:seo

Site syntax has a small trick, such as search: site:.edu

Baidu's official document should already mention most of the advanced search syntax it supports. (The way to find this document is, Baidu home-> search box above the "more >>"-> top search box to the right of the "Help"-> advanced search syntax. The spirit of exploration can help to find a lot of interesting knowledge. )

But the document lacks a very important boolean search.

require no specific query words in search results
If you find that some type of Web page you don't want to see in your search results, and that these pages contain specific keywords, then use the minus syntax to remove all the pages that contain specific keywords.
For example, the search for the sculpture of the gods, hope is about the content of martial arts novels, but found a lot about the Web page of television. Then you can query this way: God carved the Hero-TV series
Note that the previous keyword, and the minus sign must have a space, otherwise, the minus sign will be treated as a hyphen, and lose the function of the minus sign syntax. Between the minus and the last keyword, there are no spaces.

The aforementioned "Condor" is "not search", but there are also "and search" and "or search".

and search: such as search SEO + sem, the requirements of the page inside the "SEO" and "SEM." and search SEO sem results are roughly equivalent.

Or search: such as search SEO sem, requirements of the page inside the "SEO" or "SEM."

The actual use inside, such as can search: rent (site:ganji.com site:58.com), that is, can compare only two sites between the keyword ranking situation.

360 Search engines also support Boolean search, with the search instruction "and", or search is "or", such as: SEO (site:www.seoqianxian.com OR site:www.seowhy.com)

Google is supported in both types of Boolean search directives. (Baidu and 360 of the Boolean search, I use Google's documents, analogy test out)
