Advanced Search Operator Tactics -SEO

Cornerstone of Any Search Command SEO: Google Commands

Site:

Where Else You Can Use It: Google, Bing, Blekko [/site], Yandex, Baidu
*note:site:may behave slightly differently in those engines
Definition: Adding site: to your query will restrict the search results to the domain you've specified. [site:example.com]
How to Be Awesome With It: You can scan indexed URLs to get an idea of information architecture, potential duplicate content issues, and get an idea of overall number of pages indexed.
Pro Tip: Combine Site: with inurl: or allinurl: [may not work in all search engines] to analyze specific sections of a site. How big is the blog of a competitor site relative to the approximate total pages indexed? How many of those sort pages without are indexed? How many paginated pages are indexed? How many session ID pages are getting indexed? [site:example.com inurl:sort=price]. Are those pesky non-www. versions of pages getting indexed. Any time you want to analyze content within a site, the site: command is a very robust tool to have in your toolkit.

Where Else You Can Use It: Blekko [/similar]
Definition: When you use the related command, Google will return webpages that are similar to the webpage you've specified. [related:example.com]
How to Be Awesome With It: The related command has been used to find out the "neighborhood" of backlinks. However, keep in mind that there has been debate over the years on how accurate this command is for Google specifically.

Intitle: and Allintitle:

Where Else You Can Use Them: Bing, Yandex, Baidu, DuckDuckGo
Definition intitle: When you use the query in title:, Google restricts the documents it returns to those containing the term you included in the title. [intitle:keyword]
allintitle: When you use allintitle:, Google restricts results to those that contain the keyword that you specified in the title. So if you search [internet marketing] google will only fetch documents that contain the keywords ”internet” and “marketing” in the title. Notice the addition of the conjunction. [allintitle:keyword phrase]
How to Be Awesome With It: This command can be combined with a site: command to help identify templated, thin or duplicate pages by just identifying a part of the title that appears across the thin pages and searching for it. You will see about how many of those types of pages Google has indexed.

wildcard(*)

Definition: wildcard(*) to search for terms separated by 1-5 words
[internet * marketing] or [“internet * marketing”]
How to Be Awesome With It: The commands mentioned above are a great way to find articles about specific topics to build a potential list of prospects to market to. Keep in mind, though, that although these are powerful commands, they're only as good as the searcher who is performing them is clever.
