In some cases, there have been situations where there has been false advertising on the Internet. Some companies, usually the bigger companies use Internet advertisements to lure you to their site, then the so called sales or discounts aren't available. It tends to make some people wonder if the sales or discounts are available at all.
These companies know that once they get you to their site using Internet advertisements there is a slight chance you will view different areas of the site and find something you do want to purchase. This isn't illegal although it isn't right either.
Most Internet advertisements pop up or show up as banners and the information that is in the advertisement is rarely seen again. In any case, people still go to the site for the simple fact, that there could be a chance that what is on the Internet advertisement is actually available.
If this is the case, then you have accomplished to find an Internet advertisement that is actually legitimate. That's not to say all Internet advertisements aren't telling the truth, its just one way to get the individual viewing the Internet advertisement to view their site. Either way as far as Internet advertisements being trusted, that all depends on which Internet advertisements you decide to click on and check out.
Its somewhat like getting junk mail at your email address. Some times they are worth looking at while other times you just delete them. That's the same way with some Internet advertisements, some you decide to look at while others are simply the "are you kidding me" type that you could care less about really.
Internet advertisements are often found all over the Internet and in some cases, no they can't be trusted.. The simple thing most of them do is ask for email address before you even view the site, and some of us fall for it. Then of course, we all know what happens.
That specific company starts to send all types of newsletters, good deals, and discount emails to our email addresses. These are the Internet advertisements you don't really want to trust. Or they ask you a lot of different information, such as your income, your age, how many are in your household, if you are married or single, you get the idea about what I am talking about. With this in mind, if this happens when you click on an Internet advertisement it doesn't mean you must fill in the information. Just close it. I mean is it that important for you to view the site, having to give out that much information for one Internet advertisement?
I would guess that decision is up to the individual and just what it is they are wanting to view, however be careful and don't elect to put in a lot of personal information if you are unsure of the Internet advertisement. Because in the long run it could most definitely come back on you; in the form of some of your information being given to a third party or worse.
