Keyword Tools For Amazon Affiliates

The success of your business relies on you using the right tool, so we did all the groundwork for you and tested 5 of the biggest keyword tools.

Let’s see which tools came out on top!


KWFinder is a keyword research tool created by Mangools and is considered as one of their flagship products. 

It’s sleek and clean, but most importantly, it simplifies the entire keyword research process which many keyword tools have not managed to do. The KWFinder review from HPD also gave the tool a 5 out of 5 for ease of use.

It allows you to plug in a seed keyword and generate a ton of related keywords.

You can also easily assess the difficulty of any keyword suggestion by using the built-in SERP analysis or the keyword difficulty score which seems quite accurate. 

You can manage and trim down your results by using various filter options, like keyword competitiveness, specific modifiers, and monthly search volumes.

If your focus is on local SEO, this is one keyword tool you need in your arsenal.

KWFinder can help you nail down your local SEO by providing you with precise local search volume.

It’s actually very impressive just how far down you can go when selecting locations in KWFinder.

No keyword tool is perfect and one flaw is that the seed keywords don’t offer enough long tail searches if you’re using their basic plan. 


  • Low learning curve 
  • Intuitive and clean user interface
  • Rank tracker included (SERPWatcher)
  • Easy to read charts
  • City level location keyword research


  • They only have a 24 hour refund policy in place


KWFinder is definitely one of our most recommended keyword tools. The user interface is very intuitive and fast.

It uses real time metrics to calculate keyword difficulty and is considered one of the most accurate keyword tools around.

You're basically getting 3 tools in 1 so the value far outweighs the price. 


Ahrefs has a large collection of SEO tools which you can utilize to boost your search results such as: Site Explorer, Position tracker, Crawling reports, Domain comparison, and so on.

Ahrefs is primarily used for one purpose and that is to find unlimited link building opportunities and to build quality backlinks.

They crawl more than 5 billion pages per day and provide the most accurate data which will help you when doing backlink analysis. 

Site explorer: This allows you to analyze backlinks, keyword and traffic of your competitors and provides you with a detailed analysis of all their backlinks.

It also gives you a breakdown of the number of referring domains and dofollow links a site has.

Keyword explorer: One of the easiest ways to increase your search engine traffic is to do keyword research.

You want to find those keywords that are easy to rank for but still have a decent search volume.

One way to do this is to see what your competitors are ranking for. 

Their keyword explorer can help you do this and also give you a keyword difficulty score to see how easy it will be to rank for a certain keyword. 

Crawl Report: If you have common SEO issues or dead and broken links, this feature will help you find those issues.

It will also point out other site related information such as title tag errors and meta description.  


  • Comprehensive domain monitoring and comparison
  • Best backlink analysis tool
  • Email alerts help you keep a track of new and lost backlinks as well as rankings
  • Advanced filtering options
  • Converts the data into PDF or SRV files


  • Expensive and not for those on a limited budget


Their basic plan starts at about $99 per month so it is quite steep but the value being derived is worth it.

Their backlink database is second-to-none and their keyword explorer provides you with accurate data to see which keywords your competitors are ranking for.

Based on the speed of this tool, the report filtering capabilities, and the exportability of the data, this is another top keyword tool we recommend. 


SEMrush is an all-in-one competitor analysis tool created by the same guys who made the popular browser extension, SEOQuake.

They have quite a unique approach to finding profitable keywords and that is by reverse-engineering competitors organic rankings.

Since this tool was predominately built for deep competitor analysis, you will be able to uncover organic rankings as long as a domain appears in the top 100 positions in Google’s searches. 

All you need to do is create a master list of your competitors and start plugging them into SEMrush.

You will get a ton of data and be able to spy on your competitors traffic stats and the keywords they are ranking for.

Even though some stats like unique monthly visitors and keyword difficulty score are not as accurate as other tools, it’s still a useful research tool if you want to reverse-engineer your competitors best performing keywords.


  • Detailed and innovative SEO metrics
  • Can easily set up alerts for metrics like position changes or new backlinks
  • Integrates with Google Search Console and Google Analytics
  • Ideal for advertisers focusing on SEO and PPC campaigns


  • High monthly cost
  • Data discrepancies in certain parts 


When you take into account the lack of reliable link index and less than accurate keyword difficulty algorithm, it doesn’t seem worth the starting price of $99.95 per month.

Don’t get us wrong, SEMrush is still a good keyword research tool and useful for spying on your competitors.

They have a 14 day free trial so give it a spin and see what you think. Signing up requires a credit card, but the product is very good and you can get a really good test run of it in 14 days. Definitely worth it.

LongTail Pro

Long Tail Pro makes the entire keyword research process quick and easy. Enter some seed keywords, filter searches (or leave blank), and hit search. 

You will get up to 800 results back where you can click on those keywords and be able to analyze the top 10 results.

LTP is able to offer an extensive list of long tail keywords by disregarding all short tail keywords.

Where SEMrush falls short when it comes to the accuracy of keyword difficulty, LTP does a much better job. Their KW difficulty score is a lot more accurate and reliable.


  • Great for finding high traffic, low competition keywords
  • Low monthly cost for those on a tight budget
  • Majestic SEO data integration
  • Real-time filtering options


  • Calculating keyword competitiveness for 800 keywords takes quite a while
  • Interface is a bit slow and clunky 


In the words of Patt Flynn, ‘’I’m a fan of Long Tail Pro! It’s a powerful keyword research tool that I’ve used and am very impressed. I definitely recommend Long Tail Pro. It’s a must-have tool for any SEO or Internet Marketer.’’

Long Tail Pro gives you actionable data which you can use to find tons of targeted long tail keywords.


SECockpit is a paid keyword research tool created by a team of expert software developers. 

Where Long Tail Pro is behind when it comes to speed, SECockpit differs by placing more of a focus on speed.

By speed we mean processing up to 200 keywords per minute which is quite impressive. 

As far as keyword difficulty, they calculate it based on various on-page and off-page factors, and even though its not completely perfect, it will do.

The SERP analysis is pretty cool, which not only offers several different metrics to compare, but also makes things easier by color coding the data.

They just need to update their interface, it feels like Windows 98.


  • Up to 200 fully processed and analyzed keywords per minute
  • A ton of filtering options
  • Optimized for mobile use


  • No free trial offered


SECockpit offers some useful keyword research and competitive analysis functions, has a mobile app so you have access while you’re on the go, and is considered one of the fastest in terms of returning search results. 

Final Verdict: Which is the Best Keyword Tool for Amazon Affiliates?

There are different factors to take into account when choosing which keyword research tool to use.

Your choice should depend on what job you’re looking to accomplish and your level of SEO knowledge.

All in all, there are two keyword research tools which stand out in this list and they are Ahrefs and KWFinder. 

Ahrefs is for more experienced SEOs and because of their large backlink database, this makes it a no-brainer if you want to do backlink analysis.

Their keyword difficulty score is also one of the more accurate metrics compared to other tools so if you have the budget, Ahrefs is the perfect choice.

KWFinder is also one of our top recommended keyword tools and is also one of the best if you’re just starting out with Amazon affiliate sites.

The money/value ratio makes this tool a top contender.

Their keyword difficulty score is quite accurate, filtering keyword options is easy, and the user interface is easy on the eyes. 

Invest in one or both of these keyword tools and get the most accurate data and take your organic search to the next level.
