Big changes in site titles

[dvduval]

So as I pour though some of the diagnostics data for over 100,000 pages of my site I see thousands of page title that "could" be changed. Could this cause some lost traffic for a while due to the big changes?

No. But be sure that you only change the title tag on the pages and not any other meta data or anything else really. Google is more likely to ding you for a little bit to reevalaute your page, if you change more than the title tag.

Dont change anything on the pages Let them get cached, change the title tag
Let them get cached
Then make other changes.

Improving title tags will help.

Cheers!

if the site titles are leading people to something you don't sell or they are duplicate you definitely could lose traffic.
