Reply To: Halacha of Clicking On An Ad on a Webpage

Of course it’s Mutar. The advertiser has no expectation whatsoever that the only people clicking on his ad intend to buy. He probably prefers that you click anyway just on the off chance that you may change your mind. But regardless, It’s his choice to pay every time someone clicks. If you want to put it in Halacha terms, since the minhag hamedina is that people click on ads indiscriminately, that is kovea that his intention is to allow it.
