Content Spending: How much is enough?

How do you decide how much of your search budget to allocate to contextual advertising? The quick answer: as much as your budget will allow that allows you to reach your conversion goals. However, data shows that content works better for some verticals than others. Businesses whose websites match the mindset of those browsing related content will generally have more success with contextual advertising.

The average Efficient Frontier client spends 3.4% of search budget on content, but that number varies widely by vertical. Because Efficient Frontier's portfolio optimization algorithms look at the entire portfolio of keyword bids across both search and content, where spend is allocated is an indication of the effectiveness of that channel.

Dating sites experience the most success with content advertising - in December 2007, 6.4% of Efficient Frontier client spend in the dating vertical was allocated toward content. it makes sense that content is a good match for dating sites, since users are generally in the mood to meet people when browsing sites where dating-related content ads appear, and thus more likely to take the time to fill out a registration form

Automotive advertisers spent slightly more than average on content advertising in December 2007, at 3.8%. Again, the mindset of those browsing auto-related content is similar to the mindset of those visiting an auto website.

Financial advertisers' allocation of spend toward content was about average in December 2007, while Travel and Retail advertisers spend less than average on content. It seems that content advertising works very well for advertisers that have content to offer, and not as well for those for whom a conversion is a purchase. Search and shopping engines are more targeted channels for advertisers seeking to increase purchase conversions, as the mindset of the purchase-driven user is much more focused than the content-browsing user.
