Competitor Website Monitoring

A B2B SaaS company monitors pricing pages of five direct competitors. OnChange checks each pricing page every hour using CSS selectors targeting plan names, prices, and feature lists. When a competitor changes their pricing tiers, the product team receives a Slack notification with a side-by-side diff showing exactly what changed. Over six months, they build a pricing change timeline that informs their own pricing strategy.

An online retailer monitors competitor product category pages to detect new product launches and discontinued items. Using full-page monitoring, they catch layout changes that indicate new product additions. When new products appear on a competitor site, the merchandising team receives an email with a visual diff highlighting exactly what was added. This gives them a head start on sourcing similar products.

A marketing team monitors competitor homepages and key landing pages to track changes in positioning, value propositions, and calls to action. CSS selectors target hero headlines, subheadings, and CTA buttons. When a competitor repositions their messaging, the team receives a Discord notification with the before/after text, allowing them to quickly assess the strategic shift and adjust their own messaging if needed.
