Website owners gain most of their profits from putting advertisements on their website. So consequently it results in a direct relationship between the amount of advertisements on a website and the profit gained. The logical thing to do would be to jam your layout with tons of adverts, however this is actually a very bad move. This is because in order for these adverts to benefit you, visitors have to be on your website consistently or else the adverts won’t be used efficiently. With so much adverts on your website how could it possibly be attractive?
This is why you should keep the adverts at a reasonable amount meaning while still being efficient at gaining profits you should also let the web design look professional so that visitors will access your site on a consistent basis.
With all this said, it really doesn’t matter where on the website you place your adverts the important thing is that there is enough to make maintaining your site profitable and at the same time try to make it look serious and professional. Think over how you should design your web layout and see what works best for your website.
