I found long tail keywords for my new startup. What template should I use to write the blogposts?

I never thought that IH is so good in terms of helping each other.

I would like to thank everyone who helped me find out some great long tail keywords for my new startup app.

Now that I have excellent keywords. Which template or framework should I use to write my blogpost?

I have heard that list based blogposts works best.

I have also heard that long blog post like 10,000 words long also works best.
Brian Dean who ranks for many keywords on first page of google and YouTube suggested sky scrapper technique.

But I am just one person, so I need a formula or a template to use so that I do no waste too much time on only writing.

Because I know I have to generate a lot of backlinks too.

Looking for some help :)
