The VBSEO effect

I know that vBSEO doesn't work over night, but I installed @ xmas - surely I should be seeing an effect by now

I know that search engines are spidering the fourm all the time because new posts appear on google within an hour or two (plus all the new URL's have updated).

Any ideas?

Monitor your organic referrals using Analytics. That's the best way to measure the "vBSEO effect".
