I have a question over how to improve the SEo of my companies site - all comments are welcome.

The issue is that we have a site with over 4,000 pages - but Google consitently seems to index no more that 1,200 of these.

With our generic keywords we get very good rankings - many at 1 or 2 - so the site is seen by Google as good. The problem comes with the individual product pages where only some of these are indexed.

By these pages very nature they are all very similar, the difference being the specific product being advertised on that page.

Any thoughts on how to up the number of indexed pages would be appreciated.

The site is Test Equipment Solutions Ltd UK used test equipment sales and rental
