For the past year retargeting has been getting some serious attention. I've been fortunate enough to speak on it at a variety of shows, brainstorm over coffee with some cool companies and even blog about how to use it and how to leverage it for SEO. No matter who I am talking with or what the venue the number one question asked is "Who should I use for retargeting?"
Over the past two years some retargeting companies have really emerged as leaders. While we haven't used them all personally here at Moz, I thought it would be valuable to compare the companies in case any of our readers are considering retargeting. I really wanted to focus on what services each offer, what separates them from the pack and what they have planned for 2012. Luckily for us quite a few worked with us so we could really jump in with some great screenshots and specifics. For those that didn't reply to my tweet (ahem) or my email (double ahem) ... I tried to fill in best as I could based on my "research via the Web" skillz.
Okay let's get on with it. Below I compared the following companies;
-
AdRoll
-
Retargeter
-
Fetchback
-
Chango
If there is anyone you'd like to give feedback on that isn't on the list (or is for that matter) feel free to leave your thoughts in the comments!

Who are they?
Adroll has been around since 2007 rocking the display advertising world and pushing the limits on targeting capabilities. They have a hot shot team with decades of experience in optimization and creative strategy. They are based out of San Francisco, and have been making some serious waves in the retargeting space.
What do they offer?
On their basic plan they offer site retargeting with both contextual and behavioral targeting built in. They have a complete self-service interface, transparent conversion tracking, and excellent customer service.
How much do they cost?
Their Starter package has no minimum spend, if you are going to go with Plus (which gets you a dedicated account manager) you have to spend around 10k, and if you are going Pro with them (you get creatives, an engineer, and product development help) you need to be spending around 20k.
What's their secret sauce?
They are best known for their dashboard offerings and experienced team. They are truly focused on providing complete transparency into your campaigns (which a lot of other vendors are missing the mark on) and coupling it with lots of controls and options. Last year and the year before when many companies were still trying to make their platforms easy to use, AdRoll raised the bar by launching a platform chock-full of metrics and top-notch reporting options. AdRoll gets a lot of buzz because they are founded by targeting junkies who are striving to bring complex, sequence targeting capabilities to the masses. Impressive to say the least.
What's the downfall?
For those that are looking to do site retargeting this isn't really their bag. They focus mainly on retargeting and contextual targeting (which is targeting based on category of your site and similar sites rather than search query). I also think it's worth noting unless you are spending at least 5k a month in media spend you don't get a dedicated account manager, much creative guidance, or A/B testing capabilities. All of these are available at the Plus and PRO levels, but those come with higher spends. For those just starting out if you go with AdRoll you'll need to do a lot of those things yourself.
What's up for 2012?
When I asked AdRoll what they were working on they sent over a laundry list of specific action items they have set their sights on. I really appreciate the transparency. These include - focusing on making their UI even more friendly, making the dynamic creative opportunities easier to use, adding more reports to keep up their high bar of transparency, and continuing to grow the team so each advertiser has the attention they deserve.
Some screenshots for the curious cats out there...

Excellent visibility into each ad's performance, and the data you need to succeed.

Tons of options to help you intelligently build out audiences you can sequence.
You can tell from the screenshots that AdRoll has done a great job of making the data the heart of the platform. As they continue to add features it will be interesting to see how they keep the platform uncluttered and streamlined. I think it could prove challenging.
With that said, we currently use AdRoll and are loving the product and team. I think for the moderate to advanced paid marketer, AdRoll is a great option for retargeting. You have a robust product with an innovative team of minds behind it. Exciting to say the least.
Disclaimer: SEOmoz does currently use AdRoll for our search retargeting efforts.

Who are they?
ReTargeter was founded in 2009 by Arjun Dev Arora, and in three short years they have really made a name for themselves. While their roots are in site retargeting they spent the last year really branching out and now offer services around social retargeting and email marketing. They also have chosen to integrate closely with a number of other big-name products out there like KISSmetrics, and SlideShare. Also based in San Francisco, the ReTargeter team has big hopes for 2012.
What do they offer?
They have two main packages -- one for site retargeting and one that is mostly display focused for visitors that are targeted via demographics, location, or content verticals.
How much do they cost?
Both packages start at $500, and scale up from there based on the number of visitors you target and impressions you serve up.
What's their secret sauce?
Time and time again when you hear their name come up you hear they have amazing customer service. Arjun and his team are best known for being available and willing to help you out every step of the way. In fact, every client, regardless of their spend level, will have access to a dedicated Account Manager. They have taken leaps and bounds this past year in product, but their bread and butter is their dedication to account management. You can see this reflected in this awesome Thank You Letter their CEO issued at the end of 2011.
What's the downfall?
I've actually used ReTargeter in the past and enjoyed working with the team, however I did have pain points with the platform. They lacked transparency into the revenue model on their side which left me leery. I know they've worked hard over the past year to build transparency into the platform, but they still have a little ways to go here. I should also mention their pricing is a bit off-putting. While they only start at $500 (which is great) they scale up very aggressively. For a site that has 50k visits a month you are at the $2,500 range. For bigger sites, you better be ready to spend some serious coin to be working with ReTargeter.
What's up for 2012?
I asked ReTargeter what they will be focusing on and was happy to hear they are hoping to streamline their display and retargeting services into one platform, for targeting multiple devices. Companies have told them how exasperated they are working with multiple online partners, dashboards, etc. and they are planning to give that issue some serious time this year. I, for one, and super excited to hear this. I know we see this quite a bit internally and we are always look for ways to be more efficient in our channel management.
Okay here is some dashboard eye candy for you (please note this is there "soon-to-be" released dashboard):
