Wow, I'm losing faith quickly.
13 year old site. Using 13 year old code.
I decided to modernize using the cleanest of standards. I'm using the STRICT doctype (minimal errors upon validation) ... pure CSS, one stylesheet controlling everything which is minified... all pages compressed with gzip. No header information was changed... same titles, same meta. Basically I know what I'm doing.
I effectively took my average page size from 80k to 20k (before gzip compression) and the site is lightning quick. Visitors have been super happy with the improvement.
Every visitor but googlebot apparently.
The DAY after I rolled this major revision out, I began losing my major keywords. Every keyword was top 10, now I'm gone... not in supplementals - nowhere. Keywords dropped over the last 3 days... today there isn't much left.
My question... how long does it take google to "sort it out"? I'm quite certain that improvement in ranking should come from this work. It's discouraging to see everything gone completely.
What's killing me is that Google is encouraging webmasters to do everything I did to improve speed. So I actually take that to heart and get creamed? Come on, google!
