There you have it – the highest cost keywords. If you are considering entering into one of these industries, be ready to pay high cost per click rates for the top keywords. While some may start treatment facilities for the greater good, be aware that you’ll wind up in one of the most expensive niche groups, and your paid search marketing wallet will suffer from those high CPCs.

The most expensive SEM keywords may be frustrating for those in the industries, but they are the best keywords for Google, who makes 97% of revenue from advertising on Google sites (AdWords, AdSense). In the last four quarters, the biggest player of search engine history brought in $32.2 billion in total advertising revenue.

The Most Expensive AdWords Keywords

While the minimum bid per keyword is 5 cents in AdWords, the high cost keywords listed above are nowhere near that. Google can make up to $50 per click from the most expensive PPC keywords. Keyword advertising is a highly lucrative business for Google.

The most expensive niche groups paying for the most costly keywords are industries with very high lifetime customer value; the most costly AdWords keywords exist in industries where the customer pay-off is considerably high. Ultimately, the amount of money insurance companies get from an individual signing up for insurance with them makes high cost per click rates worth the investment, even at $54 a click.

Tips for Businesses in Expensive Google Keyword Niches

If you are in an industry paying big bucks for the most expensive Google AdWords key words, you will want to make sure you are implementing pay per click marketing best practices. Here are a few to keep in mind:

• Quality Score: High AdWords Quality Scores can lower your CPC and help you pay less for the most successful keywords. Tools like the Keyword Niche Finder provide you with the ability to divide large keyword lists into smaller, more segmented lists that you can easily write targeted ad text for, resulting in improved Quality Scores and better keyword rankings.
• Be Specific: Target specific, 3-5 word keywords. You can use a Google AdWords keyword tool to come up with specific keyword ideas, both broad and long tail keywords.
• Use Negative Keywords: Use a negative keyword tool to find keywords you do not want to show up for. Irrelevant keywords result in costly clicks that will never drive conversions, and when bidding on the most expensive keywords at $50 per click, negative keywords are absolutely essential.
• Focus on Relevancy
• Landing Page Optimization: While most AdWords conversion rates stay around 2%, we will often see landing pages convert at 20% or even 30%. The key to landing page optimization is to continuously try out different types of offers and test how people respond to them.
