I have been having lots of people contact me over the weekend panicing over whether they have been affected by Google’s latest algorithmic update “Farmer”.
If you have relatively stable search traffic volume it is fairly easy to detect and I have a custom report set up to do the sleuthing work.
I have actually added an extra dimension to the custom report to examine the effect on individual pages
To save you a little work you can just click this link and my custom report will be added to your Google analytics.
To use this you will then need to select the custom report and then compare date ranges. Google made the update around Wednesday/Thursday last week and currently it only affects US traffic.
I believe the “äjustment” is based on site authority which I like to liken to the quality score used in Adwords – it makes search traffic from Google more expensive for lower quality sites. This is similar to the way some other Google penalties work.
