page indexed have nothing to do with vbSEO... Google periodically drop the indexed pages to re-index them... you can also have millions of pages indexed without being found a single time when people search for your keywords -- reason is that you are not alone on the internet.

if you base the trafic on your site only on SEO, even the guys at vbSEO will tell you that it's the wrong way to do it... you have to build your community first, not the opposite.
