Our main site is a three word domain. The first two words are the product name (it's a two word product like "search engine" i.e. without both words neither can convey the product correctly) and the third word is the industry. So our domain would be, for example:
(that looks like a new religion!) Anyway, the problem being that more than 30% of people mis-spell "search" and more than 20% type in the two word product as one word so we felt we had to buy:
to be safe ... but throw in an extra well used term for widgetology plus extra tlds like .org, .net, .co.uk, .org.uk and we've ended up buying 63 domains.
Now, logically, 301ing them to the main website is the best thing for our users - yes?
How does 301ing 63 domains to another site sit with Google do you think? We had a problem with virtual hosting on our server so all 63 are on one IP address pointing to our main site on another IP address.
I know that many large sites have a lot of mispellings etc. redirecting to their main site ... but we don't have a direct phone number for Google should they penalise us!
