File scanner clean but Google still shows spam?
File scanner says your WordPress site is clean, but Google still shows spam pages, strange redirects, pharma keywords, hidden links, or Japanese keyword hack results?
Content Guard Pro scans the WordPress database for hidden SEO spam, malicious scripts, suspicious iframes, spam links, encoded payloads, and cloaked content inside posts, pages, custom post types, titles, excerpts, and Gutenberg blocks.
Most WordPress security plugins focus on files, firewalls, login protection, or vulnerability checks. Content Guard Pro adds the missing database-content layer, so you can inspect the places attackers often abuse after a hacked-site cleanup: post content, block markup, titles, excerpts, and deeper database fields when Standard Scan is enabled.
What the free WordPress.org version scans
The free plugin includes Quick Scan for wp_posts , including:
Posts, pages, and custom post types
Post titles, excerpts, and post content
Gutenberg block content stored in the database
Classic Editor and Block Editor content during single-post scans
Hidden links, suspicious scripts, iframes, SEO spam, and encoded payloads in supported content fields
The free version also includes unlimited manual scans, all findings visible, on-save single post scanning, Watch Mode weekly checks, confidence scores, severity labels, admin notices, dashboard alerts, 30-day scan history, and allowlist/denylist controls.
What this database malware scanner detects
Content Guard Pro helps find content-layer threats such as:
Hidden SEO spam links and cloaked text using CSS tricks such as display:none , visibility:hidden , opacity:0 , off-screen positioning, and tiny or hidden elements
Obfuscated JavaScript patterns such as eval() , fromCharCode() , atob() , Base64 payloads, and large data: URIs
URL shorteners and redirectors that hide the final destination
Cryptocurrency miner patterns and known cryptojacking script indicators
Encoded attacks hidden with HTML entities, URL encoding, Base64, ROT13, hex, or octal encoding
Serialized malware in postmeta, selected options, and Elementor data when Standard Scan is enabled
When to use Content Guard Pro
Use Content Guard Pro when:
Google flags hacked content, spam pages, or strange search results, but your file scanner looks clean
You cleaned a hacked WordPress site and want to check whether spam remains in posts or blocks
You inherited a client site and need to inspect the database content layer before making changes
You see pharma keywords, Japanese keyword spam, casino links, hidden iframes, or suspicious redirects in search results
You want to review risky Gutenberg or Classic Editor content before publishing
You need a database malware scanner alongside your existing firewall, file scanner, and vulnerability scanner
Why database-first scanning matters
File scanners are important, but many SEO spam infections do not live in plugin files or theme files. Attackers often inject spam links, hidden text, malicious scripts, or redirect code directly into WordPress content stored in the database.
Content Guard Pro focuses on that content layer. It is designed to complement your existing security stack, not replace it.
Think of it as database forensics for WordPress content: scan posts, pages, custom post types, block markup, and deeper database fields with a scanner built specifically for content-resident threats.
Low-noise findings for real cleanup work
Not every external link or hidden element is malicious. Content Guard Pro uses confidence scores, Critical/Suspicious/Review severity labels, accessibility-aware rules, and allowlists to reduce obvious false positives.
Findings include the affected content location, matched rule, confidence score, context excerpt, and suggested next action so you can review problems faster.

Privacy and external services
Content Guard Pro scans locally on your WordPress server and works without creating an account or connecting to the cloud service.
Optional external service: Content Guard Pro Cloud, provided by contentguardpro.com.
The optional cloud service can be used for rule-pack hints, community allowlist sync, optional anonymous telemetry, optional developer contact, and optional security newsletter preferences. It is consent-based and can be skipped.
If you choose to connect, the service may receive the site URL, site name, plugin version, WordPress version, PHP version, anonymous installation ID, consent choices, optional email address if you provide it, and anonymous scan metrics such as scan count, findings count, duration, and items scanned when telemetry is enabled.
Content Guard Pro does not send post content, database contents, matched excerpts, scan result details, usernames, passwords, payment details, visitor data, or stored customer data to the cloud service.

Frequently asked questions.
What does the free version scan?
The free WordPress.org version includes Quick Scan for wp_posts . That covers posts, pages, custom post types, post titles, post excerpts, post content, and Gutenberg block content stored in WordPress.
It also includes single-post scanning in the Block Editor and Classic Editor, unlimited manual scans, all findings visible, confidence scores, admin alerts, 30-day scan history, and allowlist/denylist controls.
Does the free version hide findings or limit scan results?
No. The free version shows all findings detected by the included Quick Scan. Detection quality is not reduced in the free plugin.
What does Standard Scan add?
Standard Scan adds deeper database scanning for wp_postmeta and selected wp_options data. This helps find malware and SEO spam hidden outside the main post content, including serialized data and Elementor data stored in postmeta.
Standard Scan is available in Premium.
My file scanner says my site is clean, but Google still shows spam. What should I do?
Run a Content Guard Pro Quick Scan first. When files are clean but Google still shows hacked content, the spam often lives in the WordPress database: posts, pages, block markup, postmeta, widgets, or selected options.
Quick Scan checks posts and Gutenberg blocks. Standard Scan adds postmeta and selected options for deeper database coverage.
Can Content Guard Pro find hidden SEO spam in WordPress posts and pages?
Yes. Content Guard Pro is built to detect hidden links, cloaked text, spam keywords, suspicious redirects, malicious scripts, and iframes stored in WordPress content.
Does it detect Japanese keyword hacks?
Yes. Japanese keyword hack cleanup often requires checking database content, not only files. Content Guard Pro can detect spam patterns when they appear in posts, pages, titles, excerpts, and Gutenberg content. Standard Scan extends coverage into postmeta and selected options.
Can it find pharma spam hidden in WordPress posts?
Yes. Pharma spam often hides drug-name keywords and outbound links inside existing posts, sometimes using CSS tricks such as display:none , tiny text, off-screen positioning, or hidden containers. Content Guard Pro scans for those patterns in supported database fields.
Does it scan Gutenberg blocks?
Yes. Content Guard Pro is Gutenberg-aware and scans block content stored in post_content .
Does it scan the Classic Editor?
Yes. Content Guard Pro supports single-post scanning in the Classic Editor and Block Editor.
Does it scan Elementor or page builder data?
The free Quick Scan checks rendered post content stored in wp_posts . Premium Standard Scan adds deeper postmeta scanning, including Elementor data stored in postmeta.
Does Content Guard Pro delete content automatically?
No. Content Guard Pro is review-first and non-destructive. The free version helps you find issues and edit affected content manually. Premium adds non-destructive quarantine, which neutralizes risky content without deleting the original database content.
Does it replace my firewall, file scanner, or login security plugin?
No. Content Guard Pro is a database-first malware and SEO spam scanner. Use it alongside file scanners, firewalls, login protection, backups, and vulnerability scanners for broader WordPress security coverage.
Will scans slow down my site?
Scans are designed to run in batches with performance-conscious limits. Content Guard Pro includes Safe Mode and throttling behavior to reduce load on typical WordPress hosting.
What happens after I fix a finding?
After you clean affected content and save the post, scan again to confirm the issue is gone. Content Guard Pro keeps scan history so you can review previous findings and cleanup progress.
Can I ignore a false positive?
Yes. You can ignore findings that you have reviewed and accepted. You can also use allowlist and denylist controls to tune scanner behavior for legitimate services used by your site.
Does Content Guard Pro send my database content to the cloud?
No. Scanning runs locally. Post content, database contents, scan result excerpts, and matched findings are not sent to the cloud service.
The optional cloud connection is consent-based and can be skipped. Optional telemetry, if enabled, is limited to anonymous scan metrics and environment details.
Can I use it after cleaning a hacked WordPress site?
Yes. That is one of the main use cases. After file cleanup, run Content Guard Pro to check whether hidden SEO spam, malicious scripts, iframes, suspicious links, or encoded payloads remain in the database content layer.
What should I check first after a scan finds issues?
Start with Critical findings, then review Suspicious findings, then Review findings. Open affected posts directly from the finding details, remove suspicious content, save the post, and scan again.
