How long for vbSEO to start generating traffic?

Just a question, and I know it all has to do with your niche, how your site is setup etc.

But my questions is,'in general', how long after installing vbSEO until you can expect traffic increase?

I installed vbSEO and the vbSEO google sitemap gnerator last night and set everything up, so I am just antsy while I wait.

Some customers are lucky enough to start seeing results in as short as a week. However, my recommendation is that your monitor your stats in 30/60/90 day periods, paying particular attention to your long tail stats.
