Hello,

Based on your comment (in the "Questions" section) it looks you were using only Backlink Checker tool and mentioned that the cost of usage of this tool is too high for you (as the reason of the refund). We reduced cost of this tool from 8 to 3 credits. In the deal there is also WordPress SEO plugin and 30+ other very advanced and specialized SEO and content marketing tools like e.g. AI article generator. Some tools requires more resources and cost but some cost 1 credit (source https://diagnoseo.com/pricing/#credits).
Some tool features don’t require any credits at all. For example, live checkpoints in the Content Editor and the Snippet Preview tool are free to use. The WordPress SEO plugin doesn’t consume credits either!

We offer a free trial on our website so every Sumo-ling can try the tools and plugin before buying.

We’ve removed the usual limits and added a massive chunk of credits that never expire. We’re giving you 12 times more credits upfront than regular monthly subscribers receive. Normally, a user has to pay a subscription fee every month to keep using credits, and any purchased credits expire after a year. Subscribers also still need an active subscription to use the credits. But Sumo-lings don’t have to pay monthly fees, and they can use their credits whenever they want—no expiration date!

Extra credits are optional and starts from as low as 1$ for 10 credits. Basic tools usage (like SEO audit or AI Article Generator) starts from 1 credit (source https://diagnoseo.com/pricing/#credits).

We added an announcement to clarify the limits, credits, and recently added new tools here: https://appsumo.com/products/diagnoseo/#from-the-founders

Kind regards,
Adam
