I create tons of articles. Using LSI and SEO keywords to make them more SEO friendly. The real hell is the keyword to text insert process. Any ways/tools/services to make it easier?
Creating tons of articles is really suspicious just like the Guest posting submission case in which Google penalize one of the most popular guest posting sites due to massive submissions of content to manipulate the rankings.
I need guest posters on my website all free of course as I have a gaming review website just created it and need content
Just search for the contents about the words you want to write about on the Google and you will find various websites covering the topics. Read them and rewrite them in your own words.
To make it "look" natural, you'll have to replace the keywords manually, there is no easy ways. Maybe you can hire someone to do the task for you.
Datacol, if you can describe the rules of inserting then it can be coded, and the process may be executed by a program. From your brief post it is not clear how you need to do this insert. I am a coder with some natural language processing experience. If you want to discuss it in detail, you can PM me.
