Sure, you can get some ideas, but they are a dime a dozen. There is no guarantee you can replicate any of those. You might fail with a better product, or thrive with something not as good.
My business could be on that page. You can put me between 5K and 7K MRR. If you go to my website, you will see a landing page with an opt-in and a blog with some articles. If you join my email list, you will also get pitched my courses when I open them.
You would still not have the slightest idea about:
- how long it takes to write articles, or why I publish them (not) that often;
- the SEO strategies I use;
- how I get traffic besides blog posts;
- how much I spend in advertising and where I advertise;
- how big is my email list;
- my positioning;
- how I write landing pages, email funnels, and sales pages;
- why I have those courses and why they are priced that way;
- my opt-in and conversion rates, and the lifetime value of a customer;
- how long it takes to create a course and how I decide what to put inside;
- all the business and copywriting courses/coaching I took and I still take;
- what I discuss with other business owners in my bi-weekly mastermind;
- how much I spend to run the business;
- how many freelancers I employ;
- what are my plans to expand;
- what I tried already and did not work;
- why the things I do work for me but might not work for you;
- and more things that don't come to my mind at the moment.
