How should a search for listing results change the URL?

Question

I have a realty site powered by selecting various options from dropdowns to find the right property. How should the listing results URLs be for SEO?

Should they all be under a single URL:

/listing-search-results/

Or should each option put a piece into the URL:

/apartments/under-100/?location=London

How does this work in terms of SEO? If I had to Google "2 bedroom house in London", how would a site with all the listings under a single URL show up in the search results?

Answer 1

URL should be short and describe your page content. I prefer

/apartments/under-100/?location=London

Descriptive is better than numbers
