Recently i have been looking at different sides of search engines and trying to find ways of manipulating algorithms with specific search queries to gain beneficial data through information retrieval. Although this can seem very intense while trying to decode the processes and the variables taken into consideration with search engine algorithms, it has lead me back to one of the basics of seo (search engine optmisation).
When first learning the science of SEO, you come across various methods that help to break down both your own sites and your competitors. These little insights are building blocks which confirm and deny any theories your may have.
Most of you will have used or at least touched upon these search queries. Google, Yahoo and MSN allows users to gain information from their search facility, but i will just look at the ones related to Google and Yahoo.
Google:
link:www.yourdomain.com
Explained : This shows all of the links that Google has indexed pointing to your domain, as most of us know the yahoo version of this is more comprehensive.
site:www.yourdomain.com
Explained: This shows the indexed pages of your site. note: if there are pages missing consider pinging your sitemap.
related:www.yourdomain.com
Explained: Industry and Company related search results.
allintitle: Keyphrase
Explained: Shows all the websites indexed by Google that have that specific phrase in the title.
allintext: Keyphrase
Explained: Shows all the indexed websites by Google that mention that phrase in the main body content of their site.
allinurl: Keyphrase
Explained: Pretty self explainiaty, but all the indexed sites that have the specific keyphrase in the domain name.
info: www.yourdomain.com
Explained: This search provides information about latest index, similar results and pages linked to your site.
Yahoo!
site: www.yourdomain.com
Explained: This shows the indexed pages of your site. note: if there are pages missing consider pinging your sitemap.
linkdomain:www.yourdomain.com
Explained: Displays all the backward links pointing towards your domain. note: Joost De Valk’s Plugin is really handy.
[www.yourdomain.com -linkdomain:www.yourdomain.com]
Explained: Provide links that display just your URL and not any keyword rich links.
These queries can be used to benefit the analysis of competitors and i am certain that there are more available. You can also apply various combinations of queries to narrow and specify your search result.
Just as a warning the figures that are giving through these queries should not be taken as 100% correct, more of a ball park figure. Any additions you have to the search engine queries would be greatly appreciated.
