If you have good content, which is helpful to your site visitors, then it is certainly good for you to grow your content. More often than not you can chart the success of a business online and see parallels with the growth of the content on their Web site that is indexed by the search engines. It makes sense also because your own pages can pass link benefits to each other, internally, within your site. Therefore it is logical that the more pages you have the more internal link popularity you can enjoy. Of course your pages all have to have a purpose and some value to the reader.
Both Yahoo and Google have introduced good Webmastering tools to help measure important data like page saturation. But if you want to see real quick where you stand at any given time, I do it like this:
Go to google.com. > Search for: site:www.yourdomain.com
On the results page, there is a blue bar at the top that tells you how many pages you have indexed in Google. Be sure to scroll down and go to the end by clicking on the last number, say page “10” for example. If you see a link at the bottom of the page that says “see ommitted results” click on it and drill to the end again. While you are here you should see if any and how many of your pages are moving to the supplemental index, which is usually not good.
You want to see your page saturation grow, it is healthy for your business online. This is an easy and effective way to quickly check your progress. This “command line” search also works in Yahoo and in MSN.
