How do I know if Google includes a page in its search?

You can find all your indexed pages with a simple, little known hack using Google itself. Head to Google and type ‘site:’ followed by your website address. For example: site:yourwebsite.com (You can leave off everything including the www). Here you’ll see all the indexed pages from your site. This is a good idea whenever you’re doing website auditing or looking for ways to improve your SEO by removing thin or irrelevant content.
