Bought Tier 2 but it's to limited for my site. I cannot test the tool fully for my website.
I wanted to add 1 big website but there are all sorts of keyword limitations in place per site.
I need to buy at least tier 4 to test it fully on 1 website since from tier 3 there is a more flexible keyword plan. With tier 2 i can only add 40% of all keywords we are found on.

Unfortunately there are no more licenses available (a couple of hours after i bought it), i can only use this tool on small websites now and it seems that if you have bigger websites you need at least Tier 3 or above to manage. I would really need tier 4 for this site and with Appsumo Plus it would be $359 for 1 website. Suddenly many similar tools are cheaper if you use it on 1 site. no such limitations are in place.
I had trust in the tool, that it would do what is promissed so i asked if i can somehow upgrade to different tier but this seems impossible, without real reson. Ofcourse they say they will come back to Appsumo but do not say when, and for what price. In the hope you don't refund but in the meantime i would not be able to use this tool fully for my website.
I waited 2 days to see if refunds would be added to the appsumo stock again but it appears it is not.

So, i am unsure about this tool. I know it took an enormous amount of time to scan the site and i cannot add another site because i used all keywords while i not even added half of the keywords i am found on.
I am not sure how it would optimize meta if it only knows 40% of important keywords. I am not gonna test this also, i can only test this fully with smaller sites.
I just wanted to optimize a complete website in an easy way and this seems not possible since the tiers are way to limited and there is no way to upgrade, or any service to make this happen.

It seems the only way forward is to refund now. Such a shame.
