Schema for Price Comparison Services - Good or Bad?

[derderko]

Hey guys,

I was just wondering what the whole schema.org markup means for people that run search engines (i.e. for a niche, certain products) or price comparison engines in general.

The intend behind schema.org was to help the engines better understand the pages content. Well, I guess such services don't necessarily want Google to understand that they're just another search engine (and thus might get thrown out of the index for polluting it with search result pages).

I see two possible scenarios: either not implement them or implement them in a way that makes the site not look like an aggregator, i.e. by only marking up certain products with unique text.

Any thoughts? Does the SEOmoz team has any advice on that?

Best,
schuon

It's going to be very difficult for sites to abuse the schema.org structure, though I don't doubt some will try.

And if a site does go that route, it's essentially a deceptive business practice, which may cause them other problems.
