They say it is not recommended to add PPC like adsense on online web store. Is that true? And why not?
Some do, but you may end up advertising your competitors products right next to yours! It's generally a bad idea!!!
Also, you want your visitors to buy something from your site, not to be attracted by some commercials (which, like someone already told you, could be exactly your competitors products).
I'm not sure but i think you can filter the ads that put on your adsense account, if that's the case then i guess you can use it, otherwise its rather stupid using adsense on your e-commerce or i'd generalize it on any professional business site. Coz those ads on your sites will definitely be about your competitors and your visitors will happily switch thereÂ
As a consumer, that would turn me off. I've actually decided not to purchase from online retailers that put Adsense and other types of advertising on their websites because it gave me the impression they were in financial trouble and I wasn't sure how the transaction would go. I want to feel confident about a company when I hand my money over.
