I have no idea how this app is or works. There’s wasn’t an option to exit out of the page were it was asking for me to review the product. So I don’t know what exactly this app is looking for as far as a review?????

Oh my what an amazing app I was able to click to download it, and then like magic the app was downloaded?!? Cool app.

Dunno yet , So asking before I ever try it gets you 3 stars...i'll change after I see changes. Thanks ...Gonna Update it to a 2 ..Now i see why you ask for reviews before using. I can do all that basic SEO work without an app. Just a teaser app to get people to pay thinking their SEO is in major need of repair. A 92 SEO score and "user accessibility:" 62 score because my page font color inst recommended..BTW no way this app brings in traffic,

We're so sorry that you had unhappy experience with our app. "92 SEO score and 62 user accessibility score" are scores based on Google Lighthouse ( with some audits, not at all of SEO.
Our application is created according to the standards of Onpage-SEO ( to make higher rank and earn traffic from rank. Customers can SEO manual without app but with our app customers can save a lot of their time to do optimize store for SEO.
I hope you understand what my app is giving our customers.

The image alt tag update is stuck with no way to restart it or reset it for a new update. Sent a helpdesk request but received no reply. Would be nice to have some support for the paid plans as ours

I downloaded the app through Shopify. The Google report wouldn't load, the page rank didn't load, the image compression didn't work, the SEO products didn't load, the SEO pages didn't load, the SEO Articles didn't load, the Broken links didn't work, the Advanced setting of linking the search console code didn't work and the search console crashed when trying to open. I thought your programme didn't load properly so I rebooted my computer. I reopened the app and nothing loaded. I am now going to cancel my subscription and remove the app from my Shopify store!

Do I have to leave a review before I can install and use this app? It looks promising but I don't like to write reviews before I've seen it in action.

I can't even see how to install this app without leaving a review. I've contaceted tech support.

So... I tried the free version of the App first just to see if I liked it. I actually uninstalled it because for a day and a half every time I logged into it I got a 503 Redirect, which is for sure not awe inspiring for an SEO company. Also they didn't notify anyone of problems, everything goes down once in a while but not updating your customers is bad in my book.

Couple things to note...

While it does compress pictures, it doesn't compress them on your home page only your collections, products, blogs and other pages... Which is weird because I would have thought that the home page would be the one you want to load faster, and that those images would be available for compression.

Audit Your Store Feature - While it's good, it uses Lighthouse which is what Google uses, it only tests mobile... It doesn't tell you what your scores are for Desktop so it's a bit misleading. They also say that they will show you how to fix the problems but they don't... Instead they offer third party fixes and things that a non-coder wouldn't even be able to figure out how to do.

Sitemap submit - I did this yesterday and have woken up to see that rather than increasing my Google rank, it's dropped, like a load stone. This seems to be the opposite of what they said it would do.

I have submitted support tickets to see what kind of response I get... But I think I might end up just canceling this app. It doesn't appear to do what they say it's supposed to do, and the keyword search and ranking doesn't seem to show that much information. I say that because I usually get an error every time I try to run it.
