Secondly, use Linkedin Premium feature (free for first month

Step 1– LinkedIn

In the LinkedIn search results, check whether

• There are lot of writers in that niche
• There are jobs posted in that niche
• What kind of freelance jobs are they offering
• Are they from reputed companies or websites in selected niche

Bonus Tip: Don’t worry about the location of the job postings and freelance writers as you are just trying to validate the market for your niche.

Secondly, use Linkedin Premium feature (free for first month) to perform the above validation for your niche. I suggest LinkedIn premium feature because it searches deeper across people, jobs, posts, groups, companies etc all at once and shows you the results in a better way.
