I'm writing a big index of documents and I'm dealing with URLs
as example I will use the car industry:
somesite.com/manifacturer-mazda_model-miata_engine-1600cc_gas_color-red_hard-top-spider_[[A LOT MORE]].htm
this url points to a generated content that can't be identified as a single resource (in practice, every keyword is a filter and the page result is generated by a database search)
at Google's eyes an URL like this looks spammy or I can use this solution with freedom?
using querystring instead of URL rewriting can fix risks? and, in this case, keywords will be considered as keyword for SERPs?
thank you in advance, feel free to correct my English!
