From the desk of Jean-Paul Sartre,

My second BST. Let’s gooooooooooooo!!!!!!!!!!!!!!!!!!

There are people out there making millions of dollars annually with display ads.

Without putting THAT much effort into it.

I spent most of the last month coding a bot that monitors the domain names and their metrics of all websites using Mediavine, AdThrive, Ezoic, Adsense, Monumetric, and 287 other networks.

I built this tool because I needed it to find niches and keywords for my AI sites. This is a big part of why my sites are so successful.

The result is my new brand — Doctor Niche

It’s a database of almost 250k websites with all the metrics from Ahrefs, SemRush, Moz, and Facebook. The number of sites will grow with time.

Doctor Niche is a software-as-a-service website with a robust database that you can filter to find those flying-under-the-radar domains.

I update the database on a monthly basis.

Metrics included in this database

You can filter and sort the database by all of these metrics:
  1. Domain name
  2. Advertising platforms the website is using
  3. Doctor Niche Score (Opportunity Score)
  4. Ahrefs DR
  5. Ahrefs External Backlinks
  6. Ahrefs Referring Domains
  7. Ahrefs Backlink IPs
  8. Moz DA
  9. Moz PA
  10. Moz Backlinks
  11. Moz Equity
  12. Semrush Rank
  13. Semrush Monthly Traffic
  14. Semrush Monthly Income
  15. Semrush Keywords
  16. Semrush URL links
  17. Semrush Hostname links
  18. Semrush Domain links
  19. Facebook comments
  20. Facebook Shares
  21. Facebook Reactions

How you can leverage this service to make money
  • Find websites that are making a lot of money while having low authority. These sites are perfect targets to “borrow” keywords and niches from.
  • Identify trending topics and create targeted content to make money.
  • Identify trends in terms of types of content, website design, and other factors that could give you an edge over your competitors.
  • Discover websites for backlink outreach.
  • Discover new link-building opportunities by researching competitors' backlink profiles.
  • Find well-performing websites that are under-monetized, which you could purchase and flip. A good example is a site in a high-RPM niche that’s still using Adsense or Ezoic. Buy the site, get it into Mediavine, and flip it after a few months.
  • Identify influencers and build relationships with them.
  • Compare the performance of websites in a given niche and use it to refine your own strategies.
  • Identify underperforming sites and offer consulting services to help them improve their performance. For example, by providing link building or a redesign of their website.
  • Create a comprehensive report on the state of the industry, which can be sold to other businesses as a data-driven marketing strategy.

How much would this data cost you if you were to get it yourself?

  • $500 monthly for the Ahrefs API
  • $500 monthly for the Moz API
  • $449 monthly for the Semrush API
  • $5,000 to hire a programmer to code the app
  • $300 for a 64-core dedicated server
  • $200 for proxies
All in all, it takes at least $7,000 to generate this database once.

And that’s without counting the endless hours you would spend orchestrating all of this.

Here's a sample screenshot of the data


2 example scenarios of how you can make money using Doctor Niche explained in detail

1. So, this is what I actually did earlier this year. Filter DA and DR < 20. Traffic > 50k. Advertiser "Ezoic." I found a site that was in a nice, clean niche, getting about 60k monthly visits, mostly from tier-1 countries. It has a DR of 2(!!) and just a handful of backlinks. I contacted the owner, and turned out the website was only slightly over $500 dollars monthly from Ezoic. Ezoic is a pretty bad display ad network. I asked how much he wanted for the site, negotiated, and, in the end, bought it for $16k. I applied to Mediavine and was accepted in 2 weeks. After a month, the site had around $18 rpm giving me about $1,200 monthly income from ads. I started building backlinks and adding AI articles, and after 6 months, I'm at a $3k monthly profit and growing. Now I can sell the site for around ~$70-90k or wait and build the site further.

2. Filter DA < 30 and DR <15. Advertiser = "Mediavine." Income >$1,000. The result is 344 domains. Check the sites. Find 4-5 sites in a common niche, let's say cars/automobiles. Buy an expired domain with strong backlinks. Use SEO tools like Ahrefs, Semrush, or Ubersuggest to check their organic keywords. Get those sweet low-hanging easy keywords, create a site, and outrank them fast. Build a solid blog, and eventually, get into Mediavine or Adthrive and profit. The keyword research is done for you.

What’s the price to access this goldmine?

For the general public, Doctor Niche is a service with a monthly fee of $545 with dozens of users already. This price will rise while I develop the app.

For a limited time, I’m offering exclusive lifetime access to Black Hat World members for $970.

THE BEST PART - if you get the lifetime deal now, you will be eligible for every single upgrade, improvement, and data update that I will ever implement on Doctor Niche. There will never be any additional upsells.

Development Roadmap

Disclaimer: This roadmap is subject to change, and things will be added when they are ready. I will also listen to customer feedback. As per BlackHatWorld rules, you are buying the service as it is right now and not based on future potential, but I will do everything I can to develop this project further.

Does it only include English language sites? Or can I filter based on site language to find sites from my native country?
Can you say more about how the opportunity score is calculated? Does it take content quality/length into account or only other factors?

Sample please.

Satre provided me an account before launching. So here is my honest review after about a week of usage:
I was amazed at the ease of use. Was able to find multiple low DR niches, with high volume. For people with access to AI tools or who want to use programmatic SEO this data is a goldmine!

Only downside is not all data is a 1on1 match. So u still need to do your own research when u found a niche. But it helps cut down research time by ALLOT.

Sample please, and good luck with your BST. It sounds like a fantastic idea, and I wonder why no one else has tried it before. You've always been someone to think outside the box. ;)
I would ask you to keep a one-lifetime copy reserved for me, but I don't know when I will be able to work again on my online projects. :D

I was able to use this service and the amount of data is MASSIVE. I spent hours querying different metrics and searching through the competition and came out with endless ideas and different niches to tackle. Data is gold and this data, if you know how to use it, is going to open up huge opportunities. I never thought about contacting owners about trying to buy their underperforming website and building it up to flip... this is genius!

This is another fantastic buy from an another Sartre service. Great job!

Review time.

I was a beta tester for this product, and it is impressive.
This is not someone just buying and reselling a database. This is an actual database built around over 20 different variables.

Currently, there are 242,349 entries, so plenty for everyone to find something to work from.

Not only is data pulled from Ahrefs, Moz, Semrush there are also FB metrics involved too.

Great service and a huge timesaver.
