Content monitoring is the scheduled tracking of text extracted from public page HTML. It uses CSS selectors to target headings, prices, calls to action, legal disclaimers, and other visible text. Unlike visual monitoring, which compares screenshots, the content worker compares the selected text itself. It can record a changed price, rewritten headline, or newly injected visible text even when the layout looks similar. The worker uses the monitor's uptime interval, does not execute page JavaScript, and does not compare element attributes or the full DOM. When the configured rule is triggered, Visual Sentinel routes the alert through the eligible channels attached to that monitor.
Your Uptime Monitor Says “Up.”But the Content Is Wrong.
A rogue plugin overwrites your pricing. A CMS update wipes your hero copy. A bad actor injects spam into your footer. The page still loads, but the content your visitors see is completely wrong.
“Price changed from $49 to $0”
Revenue lost until someone notices
“Hero headline overwritten”
Conversion rate drops silently
“Spam injected into footer”
SEO penalty from Google
Point. Click. Monitor.
No code. No CSS knowledge needed. Just click the elements you want to watch.
Click Elements to Track
Open the visual selector on your live page. Click any element, a headline, price, paragraph, or badge. We generate the CSS selector automatically.
Or Add CSS Selectors Manually
Power users can add selectors like .price, #main-content, or h1 directly. Label each element for clear alert messages.
Get Alerted on Changes
When a scheduled content check observes a change in the selected text, the alert can include the before and after values.
Beyond Uptime. Beyond Visual.Track the Actual Words.
Text-Level Tracking
Monitor the actual text content of any element. Not just pixels, the words your visitors read.
Visual Element Picker
Click any element on your live page to start tracking it. No code or CSS knowledge required.
CSS Selector Support
Power users can target elements with .class, #id, or complex selectors. Label each for clear alerts.
Scheduled Change Alerts
Route a detected text change through the eligible channels configured for the monitor.
Defacement Signals
Surface unexpected visible-text changes and heuristic defacement signals for human review.
Works with Visual Monitoring
Content monitoring complements visual checks. Catch text changes even when the layout looks identical.
Keyword MonitoringKnow when a word goes missing or shows up.
Must contain
List the words a healthy page always shows, such as Add to cart, your phone number, or a product name. If any of them goes missing, you get an alert.
Must not contain
List the words that should never appear, such as database error, under maintenance, or a spam term like casino. If any of them shows up, you get an alert.
Keyword rules run with every uptime check and read the page source, so they also catch text that is hidden from view. Available on Starter and higher.
Who Needs Content Monitoring?
E-commerce Stores
Prices, stock labels, or product descriptions change without your knowledge.
Track .price, .stock-status, and product titles across your catalog pages.
Marketing Teams
Landing page headlines or CTAs get overwritten by a CMS update or A/B test gone wrong.
Monitor hero sections, CTAs, and key conversion copy on every landing page.
Agencies
Client sites get defaced or content is changed without authorization.
Set up content monitors for every client site. Get alerted before the client does.
Compliance Teams
Regulatory disclaimers, privacy notices, or legal text must remain unchanged.
Track legal copy, cookie banners, and compliance-critical elements automatically.
Build content alerts around the changes that cost money.
Website content monitoring works best when it is paired with status checks, visual diffs, and clear runbooks for defacement, pricing errors, and SEO spam.
