Bouncing Back A Bit:
As April closed out, I am seeing a slight improvement in stability but our site still bears the scars of the Penguin. Solid, highly relevant, plural two word terms have remained unaffected, but strangely we lost many of the exact same terms in their singular versions on which we used to rank equally well. Anyone else observe this? Long tail is still hurting too.
Traffic volume (using AWSTATS) overall looked largely unaffected, but the ratios of "total visits" to "pages" and "hits" was very erratic day to day, all month (suggesting the churn). The biggest difference was that while April had the lowest Number of total visits for the moth (this year so far), the number of pages accessed beat our best month (January ) by a WIDE margin. That would indicate a lot of bot action. The month also saw the worst April sales in seven years.
Not to state the obvious, but the Google system remains in a state of chaos for many areas. We all expect miracles and instant results, but once you understand the way they build their database networks, these upsets and variances in search results between all observers makes more sense. See: [news.cnet.com...]
Once all the 'shipping containers' settle out and begin having similar versions of data, the results will hopefully improve. I see several more tweaks they'll need to work on (the plural issue) to make results better, so hold on too your hats. It ain't over yet!
