CSS-selector monitoring
CSS-selector monitoring means tracking one specific element on a competitor's page, a price, a stock badge, a promo banner, by its CSS selector, rather than comparing the entire page as an image. This is more precise than pixel-diffing because it targets the exact piece of content that matters and ignores everything else. For a Shopify store owner, this means an alert only fires when the price or promo actually changes, not when a blog timestamp or a navigation menu updates.
