This is what they promise:

Originally I gave a 1 start because I never heard from anyone in support for several days - So, I gave up and uninstalled the app. Then someone finally reached out with a heart felt apology asking for a 2nd chance and that they had made some changes to be more responsive in the future. I gave them a second chance and they blew it out of the park. Great response time for the changes I requested.

Changing to a 5 star... Great save!

Customer service is non-existent. Because I don't believe in supporting companies with poor customer service, I uninstalled it.

Simple, quick and pleasant to look at. Definitely recommend! =]

It creates a sitemap, but not sure whether it can submit to google or bing. Support has no response

Excellent product! Thank you!! Above and beyond, best app out there for this purpose.

Great app. Get's my pages and products listed on Google within days.

I didn't know I needed this until Chi Chi sent me an email about it. Great little app that I didn't even need to install myself because Chi Chi did it for me,
Fast, excellent support.

This is a wonderful app which makes my site so easy to navigate. It blends in nicely and there is the professionally custom fit.

The app really easy to install, Chi was very helpful and quick to answer our emails and fix our issue.
I will recommend the app to my friends.

Thank you for setting up a great site map for us
