Tips on How to Use Google Indexing Date Filters

• The Google advanced search page allows you to search for pages that were recently indexed, letting you filter through days, weeks, months, and years. Here are pages from SeoBook.com indexed in the last week.
• In the URL they place as_qdr=w as_qdr=d (day) as_qdr=w (week) as_qdr=m (month) as_qdr=y (year). You can also search for multiples of these units, like search for pages indexed in the last 2 weeks by placing as_qdr=w2 in the URL string.
• If you change your content management system or add new sections to your site you can see how quickly they are getting indexed, and look for any duplicate content issues as the new pages are getting indexed by looking for pages indexed under multiple URLs.
• If you have never checked your site for duplicate content issues, but recently published content, that might also show any content duplication issues or Google indexed pages that you do not want in Google's index.
• In addition to using date based filters to find how well your site is getting indexed, you can search to see who is mentioning an idea with a footprint, or use date based filters for doing link research.
