I have a fairly stable serps ranking on Google UK - been number 1 or 2 for most keywords for the last 2 years or so. The site is very clean ie no spam, adsense etc and I follow the rules as well as possible (url is in sig link.)
About 8 days ago, I added Google Analytics coding to my home page and most of the other pages and then when checking positions for keywords we had from the serps for the home page. All my other main keywords had also dropped a few positions and only secondary pages eg my links page were showing for my key search term "Indian food".
Are the two related? Have I done something wrong when adding Analytics? Is it just a glitch?
I have not added anything else new to the site (apart from product changes).
Any advice/opinions appreciated.
