Afternoon chaps, I have an observation that I'm hoping one of you knowledgeable folk can shed some light on.
I run an ecommerce site here in the UK, dealing with one type of widget. We were hit with a manual penalty over 12 months ago, which I managed to get revoked in September. Then, in October, we were hit by Penguin and swapped our page 1 position for a page 4.
Here's the weird thing ... the page from our site that Google serves for our main keyword varies throughout the day. Traditionally, it has always been our homepage (rightly so). Then, after Penguin, it varies between individual product pages and product search result pages.
Anyone experience this or know how to 'reset' the preference back to the homepage?
