Welcome to the Q&A Forum

The following site ranks #1 in Google for almost every key phrase in their URL path for almost every page on their site. Example: themarketinganalysts.com/en/pages/medical-translation-interpretation-pharmaceutical-equipment-specifications-medical-literature-hippa/  The last folder in this URL uses 9 keywords and I've seen as many as 18 on the same site. Curious: every page is a "default.html" under one of these kinds of folders (so much architecture?). Question: How much does stuffing keywords into URL paths affect ranking? If it has an effect, will Google eventually ferret it out and penalize it?
