I have a number of websites, mainly in the accommodation industry and in the same region, all similar in 'search engine' optimisation, and immediatly after the Florida Update, I had 5 of the first 10 rankings for "lakes entrance accommodation" - now those same sites have been totally removed! (not just downgraded)
check:
www.georgebassmotorinn.com
www.coastalwaters.com.au
www.northarmpark.com
Yet websites in Metung, Paynesville and Bairnsdale have some that rank well, others that have been removed completely.
My portal site
www.gippslandlakes.com is still well ranked in most of these areas.
Explain this if you can . . . I can't!
