I'm currently writing a blog post about schema.  However I want to set the record straight that schema is not exactly the same as structured data, although both are often used interchangeably.  I understand this schema.org is a vocabulary of global identifiers for properties and things.   Structured data is what Google officially stated as "a standard way to annotate your content so machines can understand it..." Does anybody know of a good analogy to compare the two? Thanks!

Hi Folks, Over the last 10 months we have focused on quality pages but have been frustrated with competition websites out ranking us because they have bigger sites.  Should we focus on the long tail again? One option for us is to take every town across the UK and create pages using our activities.  e.g. Stirling
Stirling paintball
Stirling Go Karting
Stirling Clay shooting We are not going to link to these pages directly from our main menus but from the site map. These pages would then show activities that were in a 50 mile radius of the towns.  At the moment we have have focused our efforts on Regions, e.g. Paintball Scotland, Paintball Yorkshire focusing all the internal link juice to these regional pages, but we don't rank high for towns that the activity sites are close to. With 45,000 towns and 250 activities we could create over a million pages which seems very excessive!  Would creating 500,000 of these types of pages damage our site? This is my main worry, or would it make our site rank even higher for the tougher keywords and also get lots of traffic from the long tail like we used to get. Is there a limit to how big a site should be? edit

Client wishes to drop the .php extension on all their pages (they've got around 2k pages). I assured them that wasn't necessary. However, in the event that I do end up doing this what's the best practices way (and easiest way) to do this? This is also a WordPress site. Thanks.
