Why Cornerstone Content Works

“The pillar page was a new concept to us, and we were a bit skeptical. It seemed like an awful lot of text. But we trusted Rivergate, and they patiently educated us on the value of the pillar page (as they do with many marketing strategies) so we went forward with it. We are very pleased with the amount of traffic we’ve been getting and our keyword ranking. Our controls team sees a steady stream of work and we’re now hiring to keep up with the demand.”

Rivergate Marketing’s system integrator client Applied Manufacturing Technologies (AMT) was experiencing underutilization of the controls engineering team.

The revamping of AMT’s existing industrial controls design webpage provided a natural experiment to quantify the results of developing cornerstone content versus using standard website copy and organization. In the 14 months since the new industrial controls cornerstone content went live, there has been a dramatic increase in pageviews, form submissions, and keyword rankings.

A “cornerstone,” “pillar,” or “flagship” content page on your website is a user-friendly, educational guide to a core component of your business. It contains relevant, helpful links both to your internal supporting material such as articles, case studies, and videos, and also external links to reputable outside authorities on the subject. Think of it as a clearinghouse for content related to a certain topic. A new way to organize material, cornerstone content pages are long-form and are highly rewarded by search engines for their usability for website visitors.

AMT’s industrial controls team was experiencing underutilization and an analysis showed that many potential clients thought of the company as a system and robot integrator, and were unaware of the company’s turnkey industrial controls services.

AMT’s existing industrial controls webpage was short, with a length of 523 words, and it was formatted mainly as bulleted lists of industries, processes, and keywords. The only link on the page was to a contact form; there was a single generic image and no additional supporting information.


To increase awareness, AMT’s industrial controls webpage was revamped as a cornerstone content page, and served the dual purpose as a sales tool for contacts and prospects.

Rivergate Marketing conducted several in-depth interviews with the AMT controls team, which formed the basis for the new content. The revised industrial controls page now boasts 2700 words and eight images which focus on providing educational (not sales) content. The 16 links are broken down as follows: 10 related articles, 3 videos or video playlists, 2 case studies, and 1 call to action (CTA). The many anchor text links provide easy navigation of the lengthy document.
