So, I'm reading this news about the most recent PLU update and this got me thinking: it has been more than a year since Google's preview snippets for my site have all became wrong. I chucked it up to Gbot parsing the CSS wrong ( though it works in all browsers I care about) and never really got around to fixing it.
Basically, what happens is that I assume they cannot see any of the images and a large portion of the header has collapsed and all of the content (including some ads - hence the PLU connection) moved up into the ATF. Also, some of the content mysteriously disappeared - I can only guess that its DIV got pushed into the space that's outside of the preview picture size.
So, with page layout now a ranking factor, how exactly are they going to rank a site that they cannot properly render automatically?
Does anyone already have experience with layout based ranking changes? My site has seen a small dip beginning on the 7th but I'm not sure if PLU is involved at all here - I've seen these dips before and they seem to right themselves (though not always)
Thanks for your comments and ideas!
