Your Site Is Up. But Is It Still Yours?

Uptime monitoring tells you a page loaded. Content monitoring tells you if it's still your page. Verify keywords, DOM elements, numeric values, and page changes — with alerts when something is wrong.

Why It Matters

A 200 OK Doesn't Mean Everything's Fine

Your uptime monitor says the page loaded. It doesn't say whether someone hijacked your domain, defaced your homepage, or replaced your content with a phishing clone. These are real threats — and a green status dot won't catch them.

Domain Hijacking

Someone takes over your domain and serves their own site. Your visitors see a phishing page, a competitor's store, or a parked page — while your uptime monitor reports everything is fine.

Website Defacement

An attacker injects their own content into your pages — political messages, spam links, or malicious scripts. The site is technically "up." Your brand is being destroyed.

Phishing Clones

Your domain gets pointed to a cloned version of your site designed to steal customer credentials. It looks identical — but it's not yours. Content monitoring catches the swap.

Broken Deploys

A deployment removes your pricing, hides your CTA, or wipes a contact form. The page returns 200 OK — your uptime monitor sees nothing wrong.

Content Drift

A CMS update changes your terms of service. A team member deletes a compliance disclaimer. Nobody notices for weeks until a customer complains — or a regulator does.

SEO Regression

A template change wipes your page titles or meta descriptions. Your rankings drop before anyone connects the two events.

Tracking Loss

Your analytics snippet disappears after a theme update. You lose days of conversion data before marketing notices the numbers dropped to zero.

E-Commerce Errors

A price shows as $0.00 or an add-to-cart button vanishes from your product page. Revenue stops flowing, but the page itself never goes "down."

Compliance Violations

Legal disclaimers, cookie notices, or required disclosures get accidentally removed during a redesign. You find out when the fine arrives.

Seven Check Types

From Simple Keywords to Complex DOM Queries

Content monitoring goes far beyond checking if a page loads. Verify that specific text, elements, values, and structures are exactly where they should be.

Keyword Presence

Verify specific text appears — prices, phone numbers, legal disclaimers.

Keyword Absence

Alert when unwanted text appears — errors, debug output, placeholders.

Regex Matching

Flexible pattern matching for phone formats, versions, dates, or structured text.

Element Counting

Count DOM elements by CSS selector. Set min/max thresholds for product grids or nav links.

Attribute Checks

Verify HTML attributes exist — alt text on images, hrefs on links, CSRF tokens on forms.

Change Detection

SHA-256 hashing catches any content change — ideal for legal pages and pricing tables.

Numeric Range Validation

Extract a number via CSS selector and verify it falls within min/max bounds. Track stock counts, prices, or scores.

No Code Required

Point. Click. Monitor.

Open the Visual Content Picker to see your live website in a preview pane. Hover over any element to highlight it, click to select, and FlareWarden generates the CSS selector automatically. No code or DevTools needed.

Smart selector generation — ignores framework classes (Tailwind, styled-components, Vue scopes) to build stable selectors
Auto type detection — detects prices, links, images, headings, form fields, and list items to suggest the right check type
Navigate within the picker — browse to any page on your site using the path bar, then pick elements from that page
Works on mobile — tap to select elements, long-press links to navigate
Text Verification

Verify Critical Content Stays on Your Pages

Pages change. Deploys overwrite content. CMS updates break layouts. Content monitoring catches these problems before your visitors do.

Presence checks: confirm text that must appear (phone numbers, legal notices)
Absence checks: alert on text that must NOT appear (error messages, debug output)
Regex patterns: match structured formats (version strings, dates, SKUs)
Case sensitivity: toggle case-sensitive matching per check
DOM Checks

Go Beyond Text — Inspect the DOM

Use CSS selectors to target specific elements on your page. Count them, check their attributes, or extract numeric values — FlareWarden checks the structure of your pages, not just the text.

CSS selectors: target any element with standard CSS syntax
Element counting: min, max, or exact thresholds for element counts
Attribute verification: check that HTML attributes exist on selected elements
Numeric extraction: pull values from elements and validate ranges
Change Detection

Know When Your Pages Change

Content changes can affect SEO rankings, compliance, and user experience. FlareWarden hashes your page content and alerts you when anything changes from the baseline you set.

SHA-256 hashing: any content modification triggers an alert
Baseline snapshots: save the current state and monitor for deviations
SEO protection: catch unintended changes to titles, headings, and meta content
Compliance monitoring: ensure legal pages and disclaimers remain unchanged

Smart Checks That Respect Your Server

Content checks use HTTP caching to minimize bandwidth. When your server supports ETag or Last-Modified headers, FlareWarden skips downloading unchanged pages entirely.

1

Add Content Checks

Create content monitors on any parent uptime monitor. Set check type, pattern, severity, and interval.

2

Optimized Fetching

FlareWarden checks ETag and HEAD responses first. Full page downloads only happen when content has actually changed.

3

Cross-Region Verification

Failed checks are verified from multiple regions before creating an incident. No alert fatigue from one-off network glitches.

Frequently Asked Questions

Content monitors are children of a parent uptime monitor. You create an uptime monitor for your URL first, then add content checks to it. Each content check runs on its own interval and can target different pages or paths under the same domain.

Content checks can run as often as every 30 seconds when your server supports ETag or Last-Modified headers (which allows FlareWarden to skip downloading unchanged pages). Without HTTP caching support, the minimum interval is 5 minutes to respect your server's resources.

Yes. You can use presence checks to verify that important keywords remain on your pages, regex checks to validate title tags and meta descriptions, change detection to catch unintended modifications to landing pages, and element counting to ensure your page structure stays intact. Together, these checks catch SEO-impacting changes before they affect your rankings.

Each content check has one of three severity levels: Critical (creates an incident and sends urgent alerts), Degraded (creates an incident with standard alerts), or Notify Only (sends an informational notification without creating a full incident). Choose the severity that matches how important each check is to your business.

Content checks run against the raw HTML response from your server — they don't execute JavaScript. This works well for the vast majority of websites because the content that matters most (page titles, meta descriptions, prices, legal text, error messages, headings, and navigation) is in the initial HTML. If your site is a single-page application that renders everything client-side, content checks will only see the initial HTML shell. For most sites, though, the server response contains everything you'd want to monitor.

Yes. Content monitoring is available on every plan, including the free plan. The number of content monitors you can create depends on your plan tier. All seven check types are available on every plan.
