  Chase Reiner: Does anyone know how important it is to have relevant keywords in a URL? I have been SEO'ing a site and it's titles aren't changing in Google search, even though I have changed the titles in SEO by Yoast. I am thinking perhaps it's because the URLS still say things like domain/our-clinic? The site is puretyclinic(dot)com ;

  Federico Sasso: If you changed the pages titles, they will eventually appear in the SERP, no matter what the URL looks like (note: G sometimes might change them).
  
  It's just a matter of time: Google has to re-crawl the URLs and re-process them. Check the cached version date of the pages in Google index, you'll likely notice their are prior your changes.
  
  Back to the original question: it's debated how important is to have "keyword rich" (not spammy) URLs. It has some impact, as many of us have been able to observe, but generally speaking don't expect miracles, it's just one of the hundreds things taken into account.
  
  The general rule of thumb is: if you need to create a new URL, better make it human/seo friendly; if it's a pre-existing URL, it's up to you, there generally are other low hanging fruits to cherry pick first, before going to the 301-and-wait process.

  Aaron Kleyla: Agreed on urls containing keywords. The focus should be on helping human visitors and not crawlers. Keyword match in urls is falling quickly in importance as a ranking signal. I still do it but in a logical, natural sense as they can provide structure.
  
  As far as titles go, if Google deems the title to not offer value or match page content, then google will display what it thinks is most useful to search users. The same is true with meta descriptions.
  
  Use Fetch as Google in webmaster tools to perhaps get faster results on meta updates. Also check results incognito or clear your cache and check again.
