Google Alerts tells you when something new about a keyword shows up in search. PageRadar tells you when a page you already know — a competitor's pricing, a regulator's rules, a careers page — actually changes. Pick the URL, and get the change in email, Telegram or Slack.
Start monitoring free →Google Alerts answers "is anyone on the web saying something new about X?". It runs your keyword against Google Search and emails you new results — as they happen, at most once a day or at most once a week. It depends on what Google has crawled and indexed, and it reports new results, not edits to pages it has already seen.
PageRadar answers "did this page change?". You give it the URL, it loads the page in a real browser on a schedule, compares it with the previous version and sends you what changed. It does not search the web, and it does not wait for Google.
An updated price, a reworded policy or a new line on a careers page is usually not a "new result", so Google Alerts may never mention it.
An alert can only fire after Google crawls and indexes the change. For a page you check because timing matters, that delay is the problem.
Alerts arrive as an email digest or a feed. If your team lives in Slack or you want a phone notification, you need something else.
Google Alerts details from its own settings: delivery by email or RSS, frequency as-it-happens, daily or weekly.

If what you want is to hear about new mentions anywhere — your brand name, your own name, a topic, a news story — Google Alerts is the right tool, and it costs nothing. PageRadar does not crawl the web or watch news. It only watches the pages you give it. Most people who use PageRadar keep Google Alerts running too.
New articles, posts and pages that mention you, across sites you do not know about yet.
Fresh coverage of an industry, a company or an event, collected from Google Search and News.
Type a keyword, pick daily or weekly, done. Nothing to configure and no account limits.
Plans, prices and limits change quietly on an existing page. PageRadar re-checks it and tells you which line moved — no new search result required.
Guidance pages, terms of service and policy pages get edited in place. Watch the section that matters and get the exact wording that changed.
Job boards lag; the company's own page is first. Prompt "only when a new product designer role is listed" and ignore everything else.
Know the day a vendor ships the feature you are waiting for, or deprecates one you depend on.
The Google Alerts habit, aimed at one URL: "notify me only when the word recall, sold out or registration open appears". The AI filter drops every other change.
Any public page. Each check loads it in a real browser, so JavaScript-heavy sites work too. Some sites with enterprise bot protection block automated checks; the monitor then shows as Blocked rather than failing silently.
Use the visual picker to watch one section — the price table, the job list, the policy paragraph — and add a plain-language prompt for what counts as a real change.
Email on every plan; Telegram, Slack, signed webhooks and RSS from $7/mo. Each alert has a one-line summary at the top and a highlighted diff one click away.
The free plan watches 5 pages daily with email alerts, and your first monitor checks every 15 minutes for its first 24 hours. Basic ($7/mo) watches 20 pages hourly and adds Telegram, Slack, webhooks, RSS, the API and MCP. Pro ($10/mo) is 100 pages every 15 minutes; Business ($25/mo) is 500 pages every 5 minutes.
No credit card required. Monitor 5 pages free, forever.
