Advertising

This disclosure describes the commercial side of calculator-concrete.org: where the money comes from and how we keep it separate from the content. It covers every page, including the tool and the guides.

Who pays for calculator-concrete.org

Concrete Calculator is free to use. Its running costs, including hosting, development and the time spent writing guides, are covered by advertising. Using the tool requires no payment and no sign-up. Advertising income does not depend on the results the concrete calculator gives you, so we have no reason to steer them.

Ads from third-party networks

The advertising on calculator-concrete.org is supplied by third-party ad networks. Which ad you see is decided by the network, normally by automated systems that consider the page and, where allowed, your interests.

We do not pick individual ads, so an ad on a page is not an endorsement by Concrete Calculator. How these networks use cookies is explained in our Privacy Policy.

Paid placements

If a link is paid for, it is labelled as sponsored where it appears. Such links are also marked nofollow (or rel=“sponsored”), so search engines do not treat them as editorial recommendations. Unlabelled links are editorial and are included only because they are relevant.

What we do not accept

Paid reviews and paid endorsements have no place on calculator-concrete.org. Products or methods named in the guides are mentioned on their merits. Nor can anyone buy the removal of a fair criticism.

Ads and your experience

Ads are the trade-off that keeps the concrete calculator free, and we try to keep them from getting in the way of the tool. Should an ad look misleading or inappropriate, tell us which page it appeared on and what it showed; we will pass the report to the ad network. An ad blocker will not stop the concrete calculator from working.

Independence of our content

Neither advertisers nor ad networks influence how the concrete calculator works or what the guides say. Our guides are written to explain the tool and its results; ads do not change their content.

Errors are corrected when we find them or when readers point them out. If you spot one, let us know at [email protected].

Questions about this statement

Write to [email protected] with any question about advertising on the site. We are happy to explain anything that is unclear.
