Mistakes in pay per click advertising are common and often very costly. Doing it right requires some vigilance and micromanaging. Here are 10 of the top mistakes people make in their PPC campaigns.

Too Few Ad Groups For Your Keywords

If you put all your keywords into just a few big and broad ad groups, it's time to restructure your account. You are missing out on important flexibility that pay per click advertising allows. Tighter ad groups allows you more focused, relevant ads.

Ignoring Negative Keywords

Pay per click advertising has placed more importance than ever on click through rates and quality scores. It is vital to fine tune your impressions by getting rid of the non-relevant phrases that are lowering those CTRs. If you are selling an item such as "software for widgets" then be certain you also have those negative keywords like "-free" if you don't have a free trial version. One way to find irrelevant keywords that are costing you is to check your log files of your site.

Weak Testing

Split-testing your ads is critical. Even the smallest of changes can boost results. In addition to testing your ad copy's "call to action" or value statements, every ad has multiple variables to test. The titles, the two lines of copy, and display url all can be optimized. If you don't have time for hands-on testing, a good professional pay per click management company can run daily split testing for you. You'd be surprised how well this can pay off.

Not Tracking Results

If you do get into testing ads and fine-tuning your keyword lists, it's only as effective as your tracking. Any PPC search engine will give you your ad spends and click through rates, but what about the bottom-line success? Knowing that you made $14,000 off of a $7,000 ad spend is fine, but if you dig deeper with your tracking you might be able to make that same $14,000 with only $6,000 a month in spend. That savings ads up.

Not Tracking Down to the Keyword-Level

Good analytics or a good pay per click management company will get your data down to the keyword level. Why pay for keywords that are not performing? That money could be better spent on keywords that are doing well or on other marketing expenses. If one keyword has an earning per click of 45 cents and another keyword has an earning per click of $1.45, you need to know. You can lower the bid on one and raise the bid on the other to drive more profits. If you aren't doing this, you likely have under-performing keywords that are leaking your account daily.

Too Generic of Keywords

While some generic keywords can drive a lot of traffic and even be very profitable, they also can be filled with pitfalls. Negative keywords may not be enough to save you from going in the red on a generic keyword. Often, the users doing these searches are at a very early stage of the research and buying process. Again, this is another important reason to track results on a keyword basis.

Ignoring the Many Long-Tail Keywords

This dovetails into the previous item. Building out lists and ads for long-tail keywords can be a time-consuming process, but worthwhile if done right. You are going to have different earnings per click for the keywords "dvd player," "sony dvd player" and "sony dvd player model DVP-NS57P/B." One consumer is doing research, while the other is likely pricing for the specific model they want and is ready to buy.

Not Monitoring Both Content and Search Campaigns

If you don't want to get burned by click fraud or poor traffic, you need to make sure your content network campaigns and your search network campaigns are separated and monitored. If you don't know what this means, chances are you are likely losing money. Ideally, you would have separate campaigns for each, along with precision analytics to know exactly what keyword from which source is converting for you in the content network.

Not Geo-Targeting a Local Business

If you draw most of your business from a local area, the big three PPC engines allow you to geo-target your keywords to that area. This will bring the local market to your doorstep on non-local keyword phrases. This can be hugely profitable.

Not Monitoring Your Campaigns With Frequency

Alright, so maybe you do not frequently monitor your EPCs at the keyword level (you should). And, you don't conduct split tests every day your ads are up (you should). It is still surprising that there are a high number of pay per click advertisers who don't continually monitor their accounts. The big three PPC engines are cracking down on poor performing ads more than ever. Many advertisers are getting stung with the "Inactive for Search" label on their keywords. If you don't monitor your accounts, Google, Yahoo and MSN may have plucked some of your keywords off their networks. And, with that, some of your profits.
