WatchFor alerts when a required keyword disappears or a forbidden one shows up. [Get started for free](/auth/sign-up)[View pricing](/pricing) ## Comprehensive Keyword Monitoring Features Everything you need to verify your pages say the right thing ### Required Keyword Checks Confirm that expected text is present on every load — a price, a copyright year, an "Add to cart" button, or any phrase that means the page rendered correctly. ### Forbidden Keyword Detection Flag the words that should never appear, like "Error", "Out of stock", or "Account suspended", so a broken or defaced page opens an incident. ### Defacement Alerts Catch vandalized pages by watching for the words an attacker leaves behind, such as 'hacked by', or for required text that disappears. For injected scripts, hijacked forms and redirects, add a page integrity monitor. ### Beyond the Status Code A page can serve a perfect HTTP 200 while showing the wrong content. Keyword checks read the actual response body, so silent CMS failures never slip through. ### Smart Alerting Get notified once a failed keyword check is confirmed, usually within a couple of minutes, via email, Slack, Discord, webhooks and the other channels, with the text the rule looked for in the incident. ### Multi-Location Confirmation Content checks are re-run from several locations before an incident opens, so a single odd cache or A/B variant never pages you with a false alarm. ### Historical Reports Review when content checks passed or failed over time with clear graphs, ideal for proving page health and spotting how often a page silently breaks. ### Flexible Scheduling Check as often as every minute on Starter and Pro or every 30 seconds on Business (every 3 minutes on Free), and use maintenance windows so deploys and planned content changes never trigger alerts. ## A closer look Mark the monitor down when a regex matches, here a vendor's status JSON. Each keyword check also tracks uptime, response time and the certificate. ## Why Choose Our Keyword Monitoring Solution? Status-code and uptime checks tell you a page responded — keyword monitoring tells you it responded with the right thing. By reading the actual page content from global probe locations and confirming failures across regions, you catch broken templates, expired pages, defacement, and silent CMS errors within minutes of them appearing. It's the difference between knowing your site is up and knowing it's actually working.

Matching ignores case unless you switch the rule to case-sensitive. 3 ### Monitor 24/7 Probes in the regions you chose fetch the page on your interval and scan the response body for the keyword rule you set. 4 ### Get Confirmed Alerts When a required word goes missing or a forbidden one appears, the page is re-checked from other locations. Once the failure is confirmed, you get a notification and an incident timeline. ## Keyword Monitoring Use Cases Perfect for any page where content correctness matters ### E-commerce Product Pages Make sure "Add to cart" stays visible and "Out of stock" never appears by accident. Catch pricing glitches, sold-out errors, and broken product templates before they cost you sales. ### Defacement & Security Detect when an attacker injects spam, redirects, or vandalism into your pages. Watching for unexpected text turns keyword monitoring into an early-warning system for site compromise. ### CMS & Template Health Spot silent rendering failures where a page returns 200 but shows a blank region or a stack trace. Keyword checks confirm your headlines, footers, and key sections actually rendered. ### Campaign & Landing Pages Verify that promo copy, prices, and call-to-action text appear exactly as intended during a launch. Get alerted within minutes if a landing page expires or reverts to the wrong content. ## Frequently asked questions Everything you need to know about keyword monitoring [All questions→](/faq)[Ask us directly](/contact) What is keyword monitoring? Keyword monitoring fetches a web page and checks whether specific text is present or absent in the response. You can require that certain words appear (proof the page rendered correctly) or that certain words never appear (proof the page isn't broken or defaced). It checks what the page actually says, not just whether the server responded. How is this different from uptime or status-code monitoring? Can I check for both required and forbidden keywords? How does this help detect website defacement? Is keyword matching case-sensitive? How often are keyword checks performed? What happens when a keyword check fails? Can I monitor pages behind a login or on private servers? Can I bring my keyword monitors over from another tool? ## From our blog Guides, deep-dives, and best practices from the WatchFor team [Monitoring ### Keyword Monitoring: catching the '200 OK but broken' page Feb 12, 2026·3 min readRead article](/blog/keyword-monitoring)[Monitoring ### How to Monitor a Website (a step-by-step guide) Feb 20, 2026·3 min readRead article](/blog/how-to-monitor-a-website)[Networking ### 404 Not Found: what it means and how to handle it Mar 12, 2026·3 min readRead article](/blog/404-not-found) ## Ready to Start Monitoring Your Page Content?
