I'm giving this product a 5 tacos reviews, even if it can progress.

First of all, you don't have that a lot of apps that help you track your backlinks. Yes of course you can pay SemRush, Ahref or any other solution, but the recurring cost is way too high only to track backlinks.

Yet backlinks are 1 of the 3 main ranking factors Google use, and from what we've seen with their March update, it seems they will rely more and more on off-site seo signals to rank sites, instead of on-site.
If you don't know much about SEO, to make it clear: a brand new site full of content but with not backlinks will not be able to rank well anymore. People abused AI content generation, Google is mad and forcing a fix.

So why the 5 tacos if the product can progress? Well first, the price as I already said, it is quite cheap (for the value it provides) and you don't need you to have a Moz API key (quite limited) or any other subscriptions.

I've spent the day talking with Alex about the product, and he seems very commited to make sure the product provides great value for SEO and "the average" SMB business owners managing their website by themselves.

He has a Slack in place with advanced users to help him identify areas of development quicker, and test new features with real world data.

Appsumo in my opinion should have more product like this, not totally polished yet but with passionate people who wants to provide value for the market, instead of copying the same product for the 100th time.

If you are unsure, just buy the first Tier, for the price you'll get real ROI (if you are serious about ranking your site).
