In today’s day and age, when we want to buy something, our knee-jerk reaction is to head to Google (or whatever search engine we use). Whether we know exactly what we want, are looking for nearby businesses, or want to do more in-depth research, 71% of buyer journeys begin with a search engine.

In other words, consumers have the highest purchase intent when on search engines. This is why paid search ads are so highly effective—and yet so competitive.

    Click-through rate factors into your Quality Score and guides you in identifying the right targeting, ad copy, and offers for your ads. The metric can be misleading by itself, so be sure to analyze it with respect to other metrics (like conversion rate).

    • We found the average click-through rate across all industries to be 6.18%, ranging from 3.84% to 10.67%.
    • Industries with the highest average click-through rates include arts and entertainment (10.67%), travel (8.54%), and real estate (7.75%)—with sports and recreation just behind that (7.73%).
    • Industries with the lowest average click-through rates include attorneys and legal services (3.84%), home and home improvement (4.21%), and dentists and dental services (4.69%).

    In our previous benchmarks reports, we have consistently found the highest click-through rates in the travel and arts industries, and the lowest with legal, health, and home industries.

    On the other hand, sports and fitness have historically had lower click-through rates than what we’re seeing here, and the personals vertical has shown significantly higher click-through rates than these numbers.

    While cost per lead measures how much you spent to get someone who clicked on your ad to contact you in some way, conversion rate tells you just how many people who clicked on your ad actually converted.

    • Industries with the highest conversion rates include animals and pets (19.19%), physicians and surgeons (19.15%), and automotive repair, service, and parts (15.23%).

    Our past data also finds the highest conversion rates in the legal and automotive verticals and the lowest in real estate and apparel. On the other hand, the personals conversion rate has historically been higher than what we’re seeing here.
