How many PPC blog posts do you read in a week? How many do you actually take action on? I’m guilty of reading a lot and acting too little. Much of the information published on optimizing your PPC campaigns is very interesting and insightful, but maybe not particularly actionable (or it can be difficult to take action easily). So when you see something that's actionable and easy to try, don’t just read and tweet! Actually try it!
Slow down and ask yourself how you can leverage this new knowledge in your own campaigns. That’s what I did, just a few weeks ago when Tom Demers wrote this article about using symbols in PPC ad text .
Was this the first time I’d ever heard of using symbols? Nope. But the last time it was on my mind , I didn’t take action, so I didn’t reap the benefits. It’s too easy to get distracted and forget to try those great tips you come across every day.
Here’s what Brad Geddes had to say about the using symbols  back in 2009:
Honestly, I wish they hadn’t written the post. I tested out adding symbols with a company in 2002 and found that in highly competitive industries it can definitely help CTR. In highly researched industries (such as b2b), it can make a critical difference in your ad copy success.
It was easy to see that using symbols is a great tip, so this time I immediately took action and added the “®” symbol to all of the text ads in most of my campaigns (where it made sense). I just copied the existing champion ads and added the symbol. I didn’t write any new copy—it was just one simple change.
After 30 days of monitoring my results using my PPC ad testing  spreadsheet, my entire brand campaign is up in total conversions by 12.6%. That’s a big deal for a campaign that’s been tested and optimized consistently for several years. It also proves that you should always be testing, even when you think you’ve got the perfect ads.
About 2-4 hours of work for 12.6% lift and not having to worry about any complicated analytics, etc. = awesome, enjoyable ROI.
Here are the results for one ad group in my brand campaign with an 89% improvement:
Here’s what the cumulative totals for CTR, Conversion Rate, and Conversions-per-Impression  look like:
As you can see, the treatment with the “®” symbol pulled ahead nicely. I am still analyzing the results from my other campaigns, but I have already seen some very positive results.
