U.S. Ecom site way up but zombieish traffic. What I'm seeing a lot of is two keyword searches where the words one way may put you on one site flipped the other way they have a different meaning and would put you on another site...google seems a little lost. Maybe this is google suggest gone bad? Maybe but I think it's more google misunderstanding the semantic similarities of language in some cases.
Medical searches are still a mixed bag. The old business I worked for spiked after the 19th and an unrelated b2c had its busiest day today in traffic. Both report conversions were proportionately bad. Our site, record traffic but the bounce rate is up 10% grows at a consistent ratio with the increased traffic. ToS decreases.
Based on everything we all are seeing I'd say there will be more tweaks soon. As the spam got dropped a lot of shuffling took place and what we are seeing is the testing to see who belongs where.
