Our verdict on MozCast

MozCast turns day-to-day changes in Google’s organic search results into a daily temperature, giving marketers a public way to monitor ranking turbulence. It compares page-one results with the previous day across a hand-picked set of 10,000 keywords, sampled across 20 industry categories and five major US cities. The focus is on spotting broad changes in Google search, so it suits SEO professionals who want a free overview of volatility rather than a report centered on their own tracked keywords.

The breadth of its sample and its history of volatility readings make MozCast useful for comparing turbulence over time. Its Feature Graph adds a separate view of major SERP features, including Featured Snippets, Local Packs, and Top Stories. Users can select individual features or combinations to view sample searches. That makes the tool more informative than a single volatility reading when the question is whether the search results themselves are changing, not just how much they are shifting.

MozCast is a focused monitor, not a full rank-tracking suite. Its measurements come from the selected keyword set and five US cities, so teams needing visibility into their own keyword portfolio or a wider location footprint should choose a broader tracking tool. The public tool is free and available on the web, which makes it a straightforward option for checking Google turbulence without a paid plan. Choose MozCast for a broad, historical signal on Google ranking and SERP feature changes; look elsewhere if you need ongoing tracking of specific sites and keywords.
