SEO article writer content writer

We are after an article writer, with English as their first language to support our SEO team.

The articles need to be between 350-450 words focused on specific and pre defined phrases that we use to optimise our seo campaign.

We envisage that there would be approx 5-10 articles per month of this length.

A few of the articles that we are writing at the moment include the following keywords. The keywords have to appear about 2 or 3 times in the articles.

biology revision course
physics revision course
maths revision course
economics revision course
business studies revision course
french revision course
biology as revision course
biology a2 revision course

I have attached one of the articles that we have written recently. This article took about 15-20 minutes to write. I would expect that an article of about 400 words would take in the region of 15-20 minutes to write as well.

Thank you!
