Welcome to the Q&A Forum

Thanks David, much appreciated.

It is always tricky You question is quite dangerous to SEO world as it is something that is varies from case to case. As far we don't know the product, targeted market (luxury, high street?), analytic data (conversions,sales funnels?) and can't compare it - there is no clear answer to your question. Conversion rate in organic search usually depends on the social activity, referral/quality traffic that converts, brand awareness and reputation of the brand. So, it is constantly varies even in seasons! As far we don't know your situation we can't share our experience with you. And even if we would know - there is newer precise guarantee on anything as Google changing rankings/algo constantly and even if you can predict something you will be lucky if that will actually take place. Instead to be magician and predict something I would investigate analytic account closely, pull data out of organic search from previous months, compare it and then show the owner this data and tell him possibility to increase the conversions via keyword visibility boost. Hope this helps, regards, Jungles

Just to add one other bit that might be helpful... you can use Browseo to get a quick and easy "SEO View" of most any site. SEO View for that theme Its basically seen by Google as just one giant page, and not all the content is even there in the source code. -Dan
