Content Planning and Keyword Cannibalization Question

Let's say I want to rank for "best widgets", "best gas powered widgets", "best electric widgets" and "best hybrid widgets". Would it be better to write one article that includes all of these keywords or an article for each keyword?

To better explain, here are examples of the 2 options:

Option 1 - One article that includes all keywords:

• Title/H1: Best Widgets
• H2: Best Gas-Powered Widgets
• H2: Best Electric Widgets
• H2: Best Hybrid Widgets

Option 2 - Multiple articles for each keyword:

• Article 1 - Title/H1: Best Widgets
• Article 2 - Title/H1: Best Gas-Powered Widgets
• Article 3 - Title/H1: Best Electric Widgets
• Article 4 - Title/H1: Best Hybrid Widgets

If I were to choose option 1, I'm assuming it would be harder to rank for the H2 keywords.

On the other hand, if I were to choose option 2, I might be dealing with keyword cannibalization due to partial matching. For example, the "Best Gas-Powered Widgets" article might rank for "best widgets". Or the "Best Widgets" article might rank for "best gas powered widgets".

So which option would be best?

If you plan to do unique content for each keyword then i don't see a problem to use option 2. This way you have better chances to get good positions if your content is long and good enough.

why not write three articles with all of the keywords present on each of the articles.

My call would be option 1. I prefer very long articles, 10K+ words is pretty common. You can put shittons of keywords in them, without stuffing and save quite a lot on offsite SEO. Of course, you are sacrificing user experience quite a bit, so you need to make them as user friendly as possible.

Still, you don't want people to read your crap, you want them to fuck off to Amazon or wherever asap and make the seller do the conversion job for you.

sorry for digging this post but what option do you use? can you tell me?
thanks!
