What if you could tell Google to show you how many new pages it has found in the past 7 days? Or, 8 days? Or 9?
Well now you can do all these things by adding a parameter to the end of the URL of the search results page.
Let's look at the example that Matt provided, a query that shows how many new pages were added to the Google index for mattcutts.com in the past 7 days:
The key is the "&as_qdr=d7" at the end of this URL. It tells Google to limit the search to the last 7 days.
Here is a summary of the various parameters you can set, straight from Matt's post:
d[number] - past number of days (e.g.: d10)
w[number] - past number of weeks
y[number] - past number of years
You can get the results over the past 2 weeks, for example, as follows:
Fantastic! - Now you can spend every spare moment checking to see whats been indexed and whats not.
