You can add parameters to Google search URLs to modify the output.
For example, a standard Google query can be sent by typing the following text into your browser’s address bar:
http://www.google.com/search?q=keyword
To show 100 results instead of 10, append &num=100 to the URL:
http://www.google.com/search?q=keyword&num=100
A fast way to do this in Firefox is to press Ctrl-l (lowercase L) to put the cursor in the address bar, press the END button to move the cursor to the end of the URL, and then type &num=100. Then press Enter to send the query. Switching to 100 results per page is useful when searching to see if a site is included in the SERPs for a particular query. This method is faster than changing your preferences.
There are other parameters that can be added to URLs to change the output. The following table shows three that I use on an almost daily basis:
| Name | Description |
|---|---|
| &num=100 | Changes the number of results that show in the SERP. In this case it will show 100 results instead of the default 10. |
| &start=100 | Defines the starting result. In this case it will show pages starting with the 100th result. |
| &filter=0 | The filter parameter controls whether the results are going to be collapsed. If you know the query is going to show collapsed results, you can append &filter=0 to the URL. |
The following parameters are ones that I’ve recently discovered:
| Name | Description |
|---|---|
| &pws=0 | Just mentioned in SEObook, this will turn off personalized search even if you are logged into your Google Account. |
| &imgtype=face | If searching Google Images, you can append this to the URL to limit the search to only people’s faces. |
Any other ones that people find useful?
