for some reason, google no longer supports ads that help students with their assignments. They categorize it as academic cheatingThe fastest is ads of course.
The fast cheapest traffic = Facebook ads
The fast traffic that converts more = Google ads
In the long run = SEO
If you have high impression/low conversion rates (thats common in facebook ads) we should have a look at your landing page, your ads target/segmentation and your ad design. If something is wrong it has to be at one of these points, unless you're wrong at what you think it is a low conversion rate
I have recently put up a website to assist students with their assignments. How is the fastest way of getting traffic that converts. SEO, SMM, backlinks, PBN? please advice.
