What are the best ways to invest time to make money online?

Hello everyone.
What are the best ways to invest time to make money online?

I found the following opportunities researching the topic.

According to Google trends, the top four are these:
1. FBA (Fulfilled By Amazon)
2. Affiliate marketing
3. Dropshipping
4. Amazon Associates

I understand perfectly well that here are the majority - affiliates - either with Amazon or with other programs.

Still, I assume many people tried other types of business. Or may know somebody, or would like to go for it in the future.

As to Affiliate Marketing - there are four contrasting models I found so far:

1) Amazon Associates and Niche Sites (the best example is FootballSnackHelmets by Jay).
2) Amazon Associates Authority sites - may combine some info-products promotion.
3) Non-Amazon - focusing heavily on digital products (ClickBank and alike). These are a "classical SEO focused" types.
4) Digital products focused, with the exciting concept: No SEO, Instead Facebook Fan Page promotion and YouTube videos as a 'backdoor to Google search.'

FBA - is the most popular according to Google Trends. No wonder there is a ton of training on YouTube giving great value AND promoting high-ticket courses.

FBA - Private Label (when you 'make your own product' and promote it on Amazon).

And 'Dropshipping' ECom shops:
1) Facebook ads for most popular and shareable 'free plus shipping' products AND general store.
2) Niche stores focused on SEO (with PPC, or Facebook ads combined).

I watched tens hours of videos, read dozens of articles on these topics. I can't say I understand everything, but you will find my newbie perception in the comparison tables below.

I made a few tables comparing all types of business models I researched so far.

This research is a sort of 'helicopter view.' And is not 'an inch wide, miles deep' approach.

The reason for this 'helicopter view' is to understand what efforts and skills are needed to run different types of online projects.

And to make a decision - which one (or a combination) to choose to invest time, money and efforts with maximum ROI. Your feedback and experience will be very helpful.

Anyway, I hope that may be of some interest to you.

And I would appreciate very much if you could comment on ANY topics, assumptions, numbers, anything.

Thank you in advance.

Hope you will find something useful it this piece of content.

Table 1. Key Buying Factors for each model - why people are going to buy from you.

I hope all images will be Okay for desktop view. At least they look fine when viewed on a spreadsheet :)

Key Buying Factors:

Reviews

Photos of Products

Comments (crucial for FBA - comments on products listed)

Product Descriptions (Keywords and Descriptions of Products)

Payment (Crucial for eCom store)

Table 2. Key Success Factors - how to beat competition

SERP (Back Links; Rich High Quality Content; Keywords in Title for Products and/or Content)

Customer Service (for eCom store)

Ads relevance (based on Audience Insights on Facebook)

Ads spending (for Reach and Frequency)

Email list building (for repeated sales)

Cost of Products (for FBA and Drop shipping eCom stores)

Table 3. Key Things to Focus (in Red are the most important) and Niche Types

Quality of Content

Perceived Quality of Products (high quality images of products, and/or bundles)

Price of Products (should be competitive AND in some 'impulse buy' range for many business models)

Comments (Engagements, crucial for FBA - experts recommend to get a certain number of comments prior to promoting products)

Links (internal and backlinks)

Advertising (budget and relevance)

Social Media Engagement (Likes and shares)

Suppliers (Reliable and with good prices)

Customer Care (for eCom)

Table 4. Time to Set-up a Project for a Complete Newbie (hours and days)

Find a niche (or products to promote)

Keyword and competitive research

Build an asset (site, store, listings)

Create Content

Prepare ads campaigns

Setup LLC

Choose suppliers

Table 5. Efforts Expectations after Set-up

How many hours per day needed to run a business after set-up in six months after launch, and after.

Table 6. Profits/Revenue/Margins Expectations

Here is what I found so far about 'realistic' expectations. And that is one of the most interesting to me part - I would appreciate very much your feedback, experience and comments :)

These are very high level assumptions based on potential sales and 'realistic' margins FOR NEWBIES. I totally understand that it highly depends on a Niche and Efforts. But still, when you are focusing on low competition keywords, that means low traffic. And if we multiply expected traffic volume by conversion % (1-3%) we can arrive to some 'realistic' ranges.

In some cases - traffic depends on ads spending: we can roughly assess the cost per Client acquisition and the number of potential sales.

Again - these numbers are in the Range of Possible (let's say median). And there are always exceptions.

And finally

Additional Factors to Consider - Risks and Possibilities to Scale, Or Combine Different Projects (to build a portfolio of assets)

The reason for this 'helicopter view' is to understand what efforts and skills are needed to run different types of online projects.And to make a decision - which one (or a combination) to choose to invest time, money and efforts with maximum ROI.

What do you think? What is missing? What option is best for you, and why?Could you please share your thoughts, experience, ideas?

Please comment :)

Thank you VERY MUCH
