Free Advertising

Ok so am on the verge of starting my very first BIG project.
But problem is I need help from more experienced people.
My question is sort of strange but please keep open mind and try to help me out.
I need a list of legit free ways of advertising that anyone can do. By anyone I mean the average person who has no clue about IM but is smart enough to follow instructions.
Lets put it in this way. I got an clickbank review site and I have people who are willing to promote my site. They open youtube account and make videos promoting the products with a link to the site. That's one legit method but I need more, many more. I thought of forum posting but I don't know how legit that is and how much success it will have.
Hit me with ideas and thoughts, and please someone with experience or knowledge in this field pm me so that we can chat about it am open for any contributors or partners.
Thanks.

You can post in groups at fb

the follow/unfollow method works on any social media site - best on IG and Twitter. Also FB groups is good, there is a great guide somebody posted here a week or 2 ago, check it out

Part of your work to get this project rolling will be to compile this list of marketing methods. I doubt that it'll be delivered to you just like that.

Yes I understand that, but it doesnt hurt to get extra toughts and ideas here, I will need to work weeks to complete this list and then more weeks to try out to see the average results for each method.
