6years activity +400k Dynamic Page Indexed

Hi.
+400k of My dynamic Forum pages indexed in Google.
(showthread.php and more... pages with their value)

is there any risk for my indexed pages if i use VbSeo ?

1. what about Old Page ranks, Does pages will Lose Their Rank?
2. Does Google remove indexed dynamic pages in the future?

Hello Danny ,

vBSEO 301 redirects all old urls to new corresponding format. Such as if you type vbseo.com/showthread.php?t=37779 and you'll see that it will be redirected to new format. In time Google will reindex all your sites content in time and will replace old urls to new ones.

Hi Danny,

I just answered a similar pre-sale question thread yesterday in detail. have a look here:
Thinking about buying

A lot of it applies to the questions you are asking as well.

Hello ,
What about if i don't use 301 Redirects ?
is this really a problem ?
for example keep both
6years activity +400k Dynamic Page Indexed
And
vbseo.com/showthread.php?t=37779

You cannot keep both. vBSEO over-writes showthread.php with the /new-url/ style and there is no option to disable this. Futher, you don't WANT 2 urls to 1 resource. That breaks the whole goal of our product- link consensus.

is there any risk for my indexed pages if i use VbSeo ?

Given the number of duplicate URLs that can point to a certain page, there will be a definite reduction in *total* number of indexed URLs.

Those that remain however, are the ones that you want to have indexed.
