In regards to URL structure for SEO, a few key elements to consider.
Keep your URLs short – your site has done a good job of this
Ensure the your folder and content architecture has a logical hierarchy, as this is important to the search engines
For example, I’m not sure if “podio” is a keyword that the search engines will understand what content it pertains to, which makes the current hierarchy a little bit less relevant
It would be better to have your URLs go something like this: www.vungle.com/web-apps/easy-webforms-app
Use relevant keywords in your URLs
Use static URLs – your site is doing a good job of this
Keep all URLs written using lowercase letters, as URLs are case sensitive – this looks good
Use dashes vs. underscores – this looks good
