seo bookmarklets.

Visual Tag Mapping: Injects colour-coded badges before every visible heading, displaying the tag type and its exact character count.

Hierarchy Validation: Automatically flags "Skipped Levels" (e.g. jumping from an H2 to an H4) to ensure a logical semantic structure.

H1 Integrity Audit: Identifies multiple H1 tags, missing H1s, or instances where H1 text is duplicated on the same page.

Content Alerts: Labels headings with a "Ghost" icon if they contain no text. Flags any heading exceeding 70 characters with a ruler icon.

Visibility Filter: Only audits what users and crawlers actually see - ignores elements hidden by CSS.

Full Outline Panel: Lists every heading in document order with its colour-coded tag, text and character count, plus a one-click jump that scrolls straight to it on the page. Counts are colour-matched to the on-page badges, and any errors are summarised up top.

Zero Footprint: It's a simple toggle. Click once to see the data; click again to strip the badges and return the page to normal.

Colour-Coded Outlines: Wraps every visible image in a coloured border - green (alt text present), amber (alt attribute exists but is empty), red (alt attribute missing entirely).

Inline Badges: Injects a small label onto each image showing either the full alt text or a clear NO ALT / EMPTY ALT warning.

Visibility Filter: Only audits images that users and crawlers can actually see - skips anything hidden via CSS or zero dimensions.

Full Image List: A side panel lists every visible image with a thumbnail, its status chip and filename (and the alt text where present), sorted so missing and empty alts surface first. One click scrolls straight to any image and flashes it on the page.

Toggle: Click once to audit; click again to strip all badges and outlines and restore the page.

Indexability Verdict: A colour-coded banner answers the question you actually opened this for: can the page rank? It flags noindex in the robots/googlebot directives, and warns when the canonical points to a different URL (so Google may index that one instead).

Tag Coverage: Title and description (with character counts), canonical URL, robots/googlebot directives, lang, viewport, hreflang count, and the full Open Graph set (title, description, image, type) - all in one place.

Nothing Hidden: Any tag that isn't set is highlighted in red so gaps are impossible to miss.

Length Guidance: Title and description lengths get a light, informational nudge when they fall outside the usual best-practice range - framed as guidance, not a failure, since Google frequently rewrites both in the SERP anyway.

Toggle: Click once to open the panel; click again (or the X button) to close it and return the page to normal.

Smart Scope: Measures the page's main or article region where available, falling back to the body, so navigation and footers don't inflate the count.

Reading Time: Estimates reading time at roughly 225 words per minute.

Thin-Content Spotting: A quick way to sanity-check whether a page has enough substance to rank, or whether a template is padding the word count.

Most Common Words: Ranks the 15 most frequent words (common stop words filtered out) with simple bars, so you can sanity-check what a page actually emphasises versus its target topic.

Visual Rel Mapping: Draws a coloured outline around every visible link and injects a small badge showing its rel - follow (green) or nofollow/sponsored/ugc (red).

Full Rel Coverage: Distinguishes plain nofollow from the newer sponsored and ugc values, so paid and user-generated links are called out separately.

Visibility Filter: Only audits links a user can actually see - hidden and zero-size anchors are skipped.

Full Link List: A side panel lists every visible link with its rel chip, anchor text and destination URL, sorted so nofollow/sponsored/ugc links surface first. One click scrolls straight to any link and flashes it on the page.

Toggle: Click once to highlight; click again to strip the outlines and badges.

Readable Markup: Pretty-prints each application/ld+json block as indented, formatted JSON so you can actually read your structured data instead of squinting at minified source.

Type Summary: Each block is labelled with the @type values it contains (nested entities included), repeats collapsed to counts (e.g. Question ×8, Offer ×8), so you can spot the schema at a glance before expanding it.

Collapsible Blocks: Multiple scripts are listed as collapsible sections; a single block opens expanded by default. Invalid JSON is flagged in red.

Toggle: Click once to open the panel; click again or hit the X to close it.

Annotation Read-out: Pulls every link rel="alternate" hreflang tag and displays the language/region code alongside its target URL.

x-default Check: Warns when no x-default is declared - a common gap that leaves Google without a fallback for unmatched users.

Validation: Flags the three most common hreflang bugs - malformed codes (and the classic uk-for-gb region slip), duplicate entries, and a missing self-reference (the page should include its own URL in the set).

Head-Only: Reads annotations from the page source as a crawler would, in one fixed panel.

Toggle: Click once to open; click again or hit the X to close.

Auto-Discovery: Run it from any page - it finds the sitemap itself by reading the site's robots.txt, then probing the common locations (/sitemap_index.xml, /sitemap.xml and friends). No need to navigate to the sitemap first. If you are already on one, it uses that.

Recursive Index Scanning: Automatically detects and follows nested sitemaps (sitemap_index.xml), drilling down through every sub-layer until it has mapped the entire site structure.

Full Report in a New Tab: Opens a standalone dashboard listing every URL with its last-modified date - paginated, instantly searchable, and sortable by URL or date.

Monthly Trends: A second view tallies URLs by publish month, so you can see how a site's output rises and falls over time.

Export and Copy: Download the full filtered list as CSV, or copy every matching URL to the clipboard in one click. Light and dark themes included.

Live Progress UI: While scanning, a non-intrusive overlay reports how many URLs it has found and how many sitemaps remain in the queue.

Client-Side Only: All processing happens in your browser. No data is sent to external servers.

Parameter Toggling: Checks your current URL for the de-personalisation flag. If it's there, it strips it; if it's missing, it injects it - allowing instant A/B switching between your "real" view and a neutral one.

Bypasses Private Web Search (PWS): Specifically targets the parameters Google uses to tailor results based on your past clicks, account activity, and search habits.

Clean Slate Testing: Ideal for verifying rankings without clearing your browser cache or managing multiple private tabs.

This is for when you're tired of scrolling past half a page of AI-generated text just to find an organic result. It forces Google into its "Web" search mode - essentially the classic 10 blue links layout.

AI Overview Removal: Instantly kills off Gemini-generated summaries and conversational modules that currently dominate the top of the SERPs.

SERP De-cluttering: Removes most "People Also Ask" boxes, forum carousels, and rich snippets.

Hidden Parameter Access: Automatically injects or removes the udm=14 URL parameter - Google's specific internal flag for its stripped-back "Web" filter.

When Google silently filters near-duplicate results, you lose visibility of how many pages are actually indexed - and which ones are being suppressed. This switch brings them all back.

De-duplication Override: Forces omitted entries back into the SERPs, giving you the true index count.

Visual Status Overlay: Triggers a temporary, colour-coded notification (Green for ON, Red for OFF) so you can verify the filter state before the page reloads.

Cannibalisation Audit: Use it to see if your own pages are being filtered out in favour of one another - a clear sign of internal competition or canonicalisation issues.
