How to write comparison content that doesn't age like milk

Comparison content can be a high-converting marketing channel because it reaches readers actively deciding between tools, with PostHog reporting that head-to-head pages converted roughly 10% of visitors who later signed up, compared with lower rates for roundups and general blog posts. Drawing on its experience publishing about 90 comparison and alternative pages since 2021, PostHog argues that effective comparisons should acknowledge competitors’ strengths and product gaps, identify which users may be better served elsewhere, accept corrections, and prioritize reader trust over overstated claims. To address the substantial maintenance burden created by changing features and pricing, the company centralizes each competitor’s information in shared repository data files that populate multiple pages, allowing a single update to propagate broadly and enabling competitors to submit corrections through pull requests. It also uses automated “scouts” to compare its claims with competitors’ documentation and pricing, as well as its own changelog and product activity, while leaving humans responsible for reviewing and approving changes.
