In the end, deceiving your audience is one of the worst things you can do. You will lose respect and any credibility once the visitor finds out that you have misled them. Never ever to return or consider your website again.
So, when you creating your educational website don’t forget write some articles about how to write an essay or about how to write literary analysis, because reading them students will be thinking about that your website is good and after this will buy your works for cheap!
That's the thing, some people are so obsessed with writing the content, and thinking "Oh, it's the Internet, it's so easy to make a web page and be a writer", that they forget one important thing: When it comes to increased profitability of your website, you must understand that there are forces at work on the Internet that are for the most part unrelated to web design, websites, money or technology as much as they are related to human behavior.
But again, just like the Rubik's cube, every single type of common behavioris well understood. The problem is knowing how to learn more about it and use it to.... not, not your advantage. But the advantage of those people.
