I am currently trying to help promote a website based on language education. After brainstorming for weeks, nothing seems to really fit. SEO so far isn't too bad, but we do not want to rely on search engines to help promote everything. Rankings can fall in a day. Newsletters seem to be a good idea, but how would I go about doing that? Email and spam seem ok, but it seems that everyone knows what spam is and looks like today, and so do the programs that destroy it. I have thought about joining larger popup and payperclick organizations, but wouldn't that be too costly? Directories and link exchanges are already in effect, but all that they are doing is helping build a "link partners" page on other web sites.
I want to know what is thought to be the most effective form of advertising, one where an amount of money goes in, and visitors and profits come out. And I am also looking for company names. I have already done some research myself, but I need some other feedback.
I am also looking for forms of advertising that would be relevant with education. You don't see education companies advertising in spam next to the other email that says "FREE PILLS" and "1000 GROCERY COUPONS." It needs to have more of a professional look. (And what about off-line advertising?)
The point is: How would you promote an education company?
Thanks for the feedback.
