Anstrex Dropship homepage

5. BigSpy Review

BigSpy website homepage

BigSpy is an excellent tool for your advertising strategy. According to its website, it collects and stores 500,000 new ads every day from various platforms. It also updates pre-existing ads in its database daily. That's pretty cool.

The daily update implies that any data you get from the website is up-to-date and relevant.

The website stores all the creatives it gathered from various platforms. i.e., photos and videos. You can see and play videos from its library in real-time.

Key features

BigSpy has several critical features that you need to improve your success rate with ads. Check out some of the features you are likely to find useful.

  • Facebook pages. This feature will let you search for a specific Facebook page and check out all its stats. A few stats about a page include likes, the number of ads it's running, its popularity, and the top countries visiting.
  • Featured ads. Every day, the BigSpy algorithm picks the best-performing ads and places them on the featured page. All pro plan users on the platform can see these ads. If your ads appear on this page, it's time to return to the drawing board.
  • Ad tracking. You might be interested in some ads and want to monitor their performance over time. The ad tracking feature allows you to achieve this.
  • Powerful filtering algorithms. This is a typical feature of a system with a vast database. BigSpy allows you to filter through its database and find exactly what you need.


BigSpy pricing plans

Unlike other spy tools like AdSpy, BigSpy has a free plan. However, it is useless if you really want to spy on ads.

For starters, it only shows you the top three results on Facebook pages. All the other features are inaccessible using this plan.

The basic version, available for $9 a month, is technically what some companies would call a free version. Its abilities are stripped down to the most basic ones. This plan is not sufficient for a small business in a highly competitive field.

To experience the power of AdSpy, we highly recommend the Pro plan. It gives you access to nearly all the features you'd need to launch your ad campaign.

6. AdSpy Review

AdSpy website

AdSpy is an ad-spying tool. Its specialty is Facebook and Instagram ads, even though it includes ads from other platforms like Google.

Through its website, AdSpy claims it is the world's largest database of Facebook and Instagram ads.

Key features

AdSpy has various features to meet your objectives. Its goal is to provide you with the most value and a seamless user experience.

Below are some of the critical features of AdSpy:

  • Enhanced search. AdSpy's basic search is pretty good. It allows you to generate results using more than 17 parameters—this can significantly improve the granularity of your results.
  • Large dataset. AdSpy has been around since 2016. During all those years, it has collected and stored much ad data. Using the search feature, you can spy on ads that ran in October 2017.
  • Quick results. Considering the mountain of data AdSpy owns, combing through quickly to find the data you want is not easy. However, through AdSpy's capable infrastructure, its algorithms can spit out relevant results in seconds.


AdSpy pricing page

For $149 a month, AdSpy promises full customer support. Additionally, it claims it will consider any feature requests you make.

The list of benefits doesn't end there; AdSpy's team will offer tailored advice on search queries you should be using.

There is no free version of AdSpy. You can only access and use its features when you pay the full subscription amount for at least one month.

7. ProfitBusters Review

Profitbusters website home page

ProfitBusters is a tool for print on demand businesses. With this tool, you can identify trending designs from other stores.

The tool provides you with essential information about products your competition is selling.

It shows you Google trends, targeting suggestions for Facebook Ads, links to locations that could help you with design research, estimated pricing, etc.

For every product you view, you can also see a short list of similar products from which you can derive design inspiration.

Note: Unlike typical dropshipping, you can not use other people's designs in print on demand. This will cause legal issues with the owner. What you can do is draw inspiration from their work.

Key features

Freebies on the Profitbusters website

8. Ahrefs Review

Example of the Ahrefs site explorer

Ahrefs is a Search Engine Optimization (SEO) tool. The main goal behind most of its features is to help website owners improve their SEO score and rank better in search engine results.

Additionally, Ahrefs helps SEOs (SEO experts) understand better what their competition is up to. This information helps them level up and stay competitive. This is probably what you will use Ahrefs for.

Organic traffic helps you lower the amount you spend on your marketing efforts over time. However, since building organic traffic takes time, you're better off starting now.

As an SEO tool, Ahrefs is not the only player in its category. Semrush is one of its biggest and most worthy rivals. Both tools have similar features, but each has its strengths and weaknesses.

Key features

There are several major functions that Ahrefs focuses on.

Every SEO tool (yes, including Semrush) you come across will likely have these functions:

  • Keyword research. A keyword research tool helps you find and target keywords that are relevant to your website and possible to rank for. Keywords help attract more traffic to your site.
  • Competitor SEO analysis. A competitor SEO analysis tool helps you identify unique strategies and keywords that your competitors use to outrank you. You can find content ideas and keywords for your site content to stay competitive.
  • Site audit. The site audit tool helps you identify SEO issues in your website. For instance, it might identify broken links, resources that take too long to load, page load speed, site responsiveness, etc.
  • Link building. Link-building capabilities help you identify opportunities to increase the number of high-quality links that point back to your website. These are crucial in ranking higher in search results.

    It leads to an increase in the amount of organic traffic that your site receives.

Ahrefs and Semrush have at least each of these features and more.


Ahrefs pricing plans

Ahrefs has four major pricing plans. But, they no longer offer a trial period. To use the tool, you must choose a plan and pay upfront.

Don't be sad, though. If you want to use Ahrefs to monitor and improve your site's performance, you can use its Webmaster tools for free.

The plans are:

  • Lite ($99). Great for small businesses and hobbyists.
  • Standard ($199). Good for SEOs and marketing consultants, especially freelancers.
  • Advanced ($399). This plan is suitable for in-house marketing teams.
  • Enterprise ($999). This is the highest plan with unlimited access to all features. It is suitable for agencies and enterprises.

9. BuiltWith Review

BuiltWith homepage

Alright, if you have been working with Shopify for any amount of time, you've probably realized that it allows you to install and use apps.

Apps are meant to automate certain tasks and improve site performance in different ways.

You've also probably wondered which apps your competition uses. Not just this, you've probably wondered which other technology your competition uses to stay on top of their game.

Koala inspector pricing plans

Koala Inspector is hands down one of the most affordable tools so far. Considering all the features it offers you, its ultimate plan is amazing.

Use this plan if you are working on a tight budget.

The free plan is pretty decent. However, Koala Inspector limits the number of times you can use certain features by issuing credits.

The ultimate plan removes this restriction by allowing you to view as many ad campaigns as possible.

Why would you spy on other Shopify stores?

A business that doesn't spy on its competition is waiting to die. All the big companies do it.

Here are a few reasons spying on your competition should be on your to-do list:

  1. It saves you time. Ever heard the expression 'reinventing the wheel' and how unnecessary it is? Spying on your competition prevents you from reinventing the wheel. Sometimes, all you need to do is what your competition is doing.
  2. It helps you prepare. When you know what your competition is up to, you can create measures to counter their innovations and protect your market share.
  3. There is no reason not to. Do it. Your competition is probably spying on you! There is no reason you shouldn't spy on them. You only stand to gain from it by learning something new or getting new ideas.
