This is a very basic seo tool which most of free tools can help you get answers for.

Let me break this down for you :

1. It does monitor site speed (you can do it free with gtmetrix , pingdom and google page speed test ).

2. It crawls on site and give you errors which you can fix ( this again is available on most of seo wp free plugins as well )

3. It has keyword monitoring and ranking tool as well which works only 1 out of 5 times. I have tried searching for keywords in India and UK, never got any results.

4. It monitors uptime that's the only good part . However, if you are a web agency you anyways do this diligently through your hosting partner this is not a deal breaker.

5. Last but not the least, it tries helping you with on page SEO , how many back links you have got , anchor links, internal links but you can't see any details if you want to. It gives you just the total numbers. It also shares 1 word,2 words and 3 words keywords you have used with no context to it.

The UI/UX is great, its just a good-looking website which does nothing. Sorry for being bitter and harsh. Either my expectation was really high when I saw 5 stars from 429 reviews or else I know my SEO game better.
