We're unhappy with the meta descriptions google is picking up for our links in SERPs so have started using AJAX to stream in the content google was previously picking up for meta descriptions.
This worked and it doesn't seem to have impacted traffic coming to our site, however since the day of that change our bounce rates have gone up significantly, even for pages that we did not push this change to.
Is it possible that doing this caused Google to treat our site differently site wide? Is there anything we should be cautious of when doing this?
I know the bounce rates could be impacted by users being better prepared by the google meta descriptions, however it doesn't explain what's happening to parts of our site that we didn't do anything to.
