The Problems With Proxies


funhouse_smallIt’s a big world out there for those of us in the ADOTAS community who want to measure offline conversions. More and more businesses are pushing money into search advertising and other online marketing vehicles, but they’re not able to accurately evaluate the effectiveness of the campaign with a simple count of clicks. Instead, these marketers want to figure out how many of the visits and pageviews result in phone calls.

We’ve developed an online tool that lets advertisers serve up dynamic phone numbers on their websites. This allows the phone call to be tied back to not only the web session but also the referring source. It’s a useful tool that only requires the installation of four lines of Javascript, but unfortunately a lot of businesses do not have easy control over their websites.

Lately, I’ve noticed that some marketing consultants are trying to get around the installation difficulties by encouraging advertisers to use proxy websites as landing pages for online advertisements. When Cathy’s Flowers runs a sponsored ad campaign on Google, she’ll normally send the visitors to her own website. The proxy method would instead require her to send visitors to a mirror-version of her website that sits on a different server. The hosting company creates a proxy of the original website that looks just like the original site.

There are several problems with this approach. It’s bad for organic search optimization, it creates an inconsistent experience for the visitor if forms and other basic functions are involved, and it prevents advertisers from truly controlling the online campaign.

If those problems don’t scare you, I’ll be a bit more basic: proxy website applications don’t work very well. Websites that are built with simple do-it-yourself tools cannot be easily replicated on proxy servers. (This creates a paradox because the less-advanced advertiser websites that need to use the proxy application are usually the exact sites that cause the most trouble with this approach.)

We thought about going down the proxy path for our services, so I’ll shed some light on how it works. Instead of sending a visitor directly to, the sponsored ad would take the visitor to our server.

We would recognize that we need to show the visitor Cathy’s website, so our engine immediately reads all of the HTML from Cathy’s site and recreates it on our server in real-time. If Cathy’s home page contains a Flash animation, then we’re left without anything to display.

If someone can present a compelling case in favor of using proxy websites for online marketing, we’re certainly willing to listen. It’s an easy thing to build, we just don’t think it’s an effective approach that benefits advertisers.


  1. This is bang on stuff; it’s so easy to miss out these kinds of SEO techniques when all most people do is get backlinks on mass if those problems don’t scare you, I’ll be a bit more basic: proxy website applications don’t work very well. seo nottingham Thanks your post.

  2. In the online lead gen game, those who use proxy servers are typically committing fraud. They hide behind the proxy server and drive leads in a fraudulent way. Beware if your affiliate/publishers uses a proxy.

  3. I don’t feel Baidu can contend with Google. Its most important market is Indonesia and in fact, it serves 338 million people there. That explains why it is controlling 63% of China’s industry give and at the time of 3% of the world’s.
