Cerebro from Helium is part of an Amazon optimization suite with tools for:

  • Product Research
  • Keyword Research
  • Listing Optimization
  • Operations
  • Analytics
  • Marketing
  • Finance

Cerebro is included with the Product Research section of Helium, which is available for free as long as you keep the uses under two times per day. After that, the pricing starts at $39 per month and goes up to $399 per month depending on which features you need and the number of times you need to use it per day.

Cerebro is a keyword discovery tool and one a great reverse ASIN tool to take advantage of insights and analytics to get your product more exposure on Amazon. One reason we like Cerebro so much is because it has a Product Rank method which tells you the number of sales you need to achieve for a product to land on the first page of Amazon search results.

Other than that, Cerebro lets you leverage what competitors sell and how they bring in traffic, all coming together to help you boost the effectiveness of your own listings. You can also bring more awareness to your products, gauge which keywords will work for each item, and optimize product listings using some automated and manual tools. The reverse ASIN search is combined with a Product ID lookup for switching between different products and seeing rankings for keywords on each one.

What's more is that Cerebro calculates an internal IQ score to tell you which products to choose to sell. Essentially, it creates a ratio of search volume compared to competing products using a keyword. The idea is to find items with lower competition but higher search volume, and it's all merged into one score to make it easier to understand. Overall, Cerebro is a rather promising system for any type of Amazon seller, whether you're an experienced veteran, an agency, or someone just getting started.

You're able to reverse search multiple ASINs and see which keywords Amazon users like to type in to discover those types of products.

You can filter to locate high volume keywords, but also tap into lists of low competition keywords. Keyword Scout/Inspector delivers keyword ranking data, along with organic and sponsored information, as products sell online. We particularly enjoy that fact that you can view historical search volume; this essentially means that all sellers have access to monthly and yearly reports to see if any of these products have much potential in the future. This is also a wonderful tool to discover if there's any seasonality behind a certain product.

Along with the ability to gather competitive intelligence, explore keyword strategies among ASIN groups, and refine your strategy throughout the process, Keyword Scout/Inspector looks like an excellent way for individuals, agencies, and growing Amazon sellers to learn more about their competition (and the keywords being used by the competition).

The Reverse ASIN Tool from SellerApp actually comes as a completely free search bar on the SellerApp website. It's limited to just a few searches, but signing up for an account unlocks more access. You simply type in any ASIN, then switch to which Amazon site you want to look on (based on country).

Amazon sellers get to take advantage of a powerful suite of products from SellerApp, all starting at $0 per month and going up to $99 per month. The free plan lets you track two products and complete keyword research, listing optimization, and product research. The $49 per month Pro Lite plan is the starting point for professionals that want to use basic exports, advertising automation, every feature from the keyword tracker, and more.

SellerApp also prioritizes keywords with low competition and high volume, meaning you'll locate keywords for products that may not get as much use as others. There's not as much of a reason to try to win out with high competition keywords.

Finally, SellerApp produces a substantial amount of data for short listing keywords with profit potential. You'll see CPC rates, search volume, and keyword types, along with filters to organize the keyword lists, all of which come together to boost your insight into the market and get more sales.

From a seller's perspective, SellerApp makes sense if you're just getting started. But we also like it for more advanced operations, since you can never have too much information about the competition.

Which of the Best Reverse ASIN Tools Should You Choose?

From Sellzone to SellerApp, these reverse ASIN tools allow you to dig into the Amazon competition and come out ahead in the future. All reverse ASIN tools on this list work best with their premium plans, but you're able to at least test them out with free trials or through free plans. The good news is that the paid plans get covered once you make money from the results. That's the whole point; the more you use them, the more money you should make.

We recommend starting with Sellzone and working your way down the list. You'll find that each of the best reverse ASIN tools has unique interfaces that may work for some people over others. You also might need to choose one of them based on pricing. In that case, we still suggest you go with Sellzone to start since its free plan is the most powerful.
