Who Sponsors Geology.com?

Geology.com is not financed by companies, special interest groups, or contributions from anyone. Its acquisition and launch was financed by Hobart and Rosalie King. Since 2006 the website has been self-funded by advertising revenue, the same as most newspapers and their websites. We also make a small profit from items sold in the Geology.com store.

We do not sell ads directly to anyone and have no intentions of directly selling ad space in the future. The ads that appear on our website are purchased by advertisers through ad networks such as the Google Ads program. The ad networksk then transmit the ads directly to our website without our involvement. This allows us to spend our time creating content for our visitors, knowing that a trusted source is managing the ads. Allowing others to take care of the ads enables us to spend more time on what we do well and provides separation between the content that we write and our main source of revenue.

If you see an ad on Geology.com, that does not mean that we endorse the company or have any direct relationship with them. We have little control of the ads. However, we do instruct Google to block categories of ads that we believe are inappropriate for our audience and to block ads from specific advertisers that we believe are inappropriate or annoying.

If you appreciate the content that we produce, we would appreciate it if you would help us maintain our revenue by not using adblocking software when you visit our site. We spend thousands of dollars every week to produce the content displayed on this website and serve it to a worldwide audience free of charge. Revenue from the ads is what makes this possible. Thank you!
