Write generically, as this site will be rented the information must be a cross between an article and a press release. It needs to be informative while also including a clear call to action. The text needs to be at least 500 words long, and must have a kw density of around 2%.
Include your KW in the H1, H2 and H3 tags, title and description and also add a photo and alt tag it with your keyword.
If you don’t want to write an article then feel free to outsource here is who I use.
