They don't like the idea of being "tagged" and followed. It creeps them out. However, we don't have any identifiable information on them.

It's just an anonymous cookie being dropped into their browser that allows their browser to remember which pages they have visited.

And for this, people have been bashing "cookies," which are the codes we use to 'tag' users for retargeting.

Cookies Are Not Evil, Evil People Who Use Cookies For Evil Are Evil

I love cookies...

The kind you can eat and the kind your browser uses for retargeting.

Never met a cookie I didn't like ;-)

Cookies are how my browser remembers my username and passwords-which I have hundreds of.

Cookies are how my browser knows how to auto-complete my address into order forms.

Cookies are how Facebook and Gmail remember me, so I don't have to friggin login every time.

Cookies are how my affiliate links are tracked, so I get paid.

Cookies are also how certain websites choose which ads to show me, which is where retargeting comes in.

Thanks to cookies, I see ads that pertain to me. I see ads for things that may have interested me, that I've completely forgotten about.

Instead of ads that are not relevant to me.

Some people don't like them and because of that, there are settings for each browser, whether it's Firefox, Explorer, Safari or Chrome, that can prevent companies from slapping cookies on users and 'tagging' them with their codes.

As a marketer, you should love cookies.

I once had a large potential client tell me that he uses "Ad Blockers" on his computer. I stopped the conversation and told him he should hire someone else.

You can't be a deer hunter and a vegetarian.

Long story short, there will be some people out there that hate cookies and have their security settings turned up higher than Fort Knox.

The next thing you need to know is that retargeting may be going away soon. There is a war going on right now between privacy advocates and Internet browsers like Chrome, Firefox, and Internet Explorer.

They have started a "Do Not Track" movement.

As of the time I am writing this (July 22nd, 2013), all PC computers shipped with Windows 8 are default set to block cookies!

And Mozilla, makers of the FireFox browser is doing all they can to help remind all of their users how to turn off cookie tracking as well as opt-out of whole networks from tracking their actions.

Not to mention all the plug-ins and softwares that are being developed to fight, block, fool, and deny cookie tracking.

It's like pop-up advertising back in the day and all of the pop-up blockers. Except, I don't believe retargeting ads to be anywhere near as invasive as pop- up ads were.

As of the time of my writing this report, retargeting still works and it's working incredibly well. However, we're all wondering how this browser cookie war is going to play out.

Will retargeting survive? I hope so, because I'm seeing 300%+ ROI on some campaigns. You should get started as soon as you can before the window closes.

Now that you know what to watch out for, let's discuss the different networks. If you're looking for an unbiased review, you won't find that from me. I'm not scared to say something sucks if it sucks.
