Tedster, we have really noticed (1) (2) & (4). Lets take this week, traffic has looked normal but this is when looking back over the week, if we look at Wednesday we were dead until 1pm, then bam! Last we we noticed we were dead until 3-3.30pm then bam! I have been checking the SERPS using in private browsing which I ***think*** should give what a user with no search history sees? Yesterday we had our best day in ages but when I checked the SERPS they looked a complete mess! Up until Mayday our traffic was constant throughout the day and from day to day, this was mirrored with sales conversions. What we see now is sales conversions tracking traffic on a good day but on others we see spikes in traffic but no conversions, a quick look at the traffic sources reveals a lot of foreign traffic and hits from terms we really shouldn't be ranking for!(which explains why no sales conversions, G is sending people to us for things they do not want!).
To sum up, at the moment I can see no way to change your site to take advantage of what is happening, it's obvious it is still in progress & maybe for some time yet. Of course this maybe the new G-constant changes which mean massive fluctuations.
What I would like to know is how some of the big players have been affected but I doubt we will get their IT departments posting on here!
