Creating descriptive categories and filenames for the documents on your website can not only help
you keep your site better organized, but it could also lead to better crawling of your documents by
search engines.
dar tot pe acelasi blog este un alt articlo care zice:

Does that mean I should avoid rewriting dynamic URLs at all?
That's our recommendation, unless your rewrites are limited to removing unnecessary parameters, or you are very diligent in removing all parameters that could cause problems. If you transform your dynamic URL to make it look static you should be aware that we might not be able to interpret the information correctly in all cases.

If you have a dynamic URL which is in the standard format like foo?key1=value&key2=value2 we recommend that you leave the url unchanged, and Google will determine which parameters can be removed; or you could remove uncessary parameters for your users.
eu la asta ma refeream.. si articolul complet aici:

adica trebuie sa ai grija ca rewrite-ul tau sa nu faca probleme google-ului si sa nu poata indexa tot.. dar din punctul lor de vedere e aceasi chestie.. si ca felul cum arata linkul conteaza doar pentru user

concluzie: NU CONTEAZA decat pentru user .. dar fa rewrite ca nu strica..
