Frequently asked questions
Does Clarity SEO work with WooCommerce?
Yes. The SEO metabox appears on product pages, schema markup supports Product type, and products are automatically included in the XML sitemap.
Will it conflict with Yoast SEO or Rank Math?
It’s best to deactivate other SEO plugins before using Clarity SEO to avoid duplicate meta tags and schema markup. You can import your existing meta titles and descriptions from Yoast or Rank Math via the Import tool on the Settings page.
How do I add Clarity SEO to custom post types?
Use the clarity_seo_metabox_post_types filter in your theme’s functions.php: add_filter( 'clarity_seo_metabox_post_types', function( $types ) { $types[] = 'portfolio'; return $types; } );
How accurate is the readability score?
It uses the Flesch-Kincaid reading ease formula, a widely recognized standard. Scores above 60 indicate content that is easy to read for most audiences. It’s a helpful guide, but always review your content manually for context and tone.
How do I set up the Google Search Console integration?
You need a valid OAuth2 access token from the Google API Console with Search Console API access enabled. Enter the token and your site URL (e.g., sc-domain:example.com) in Clarity SEO → Settings.
Can I exclude a page from search engines?
Yes. In the Clarity SEO metabox on any post or page, check the “Noindex / Nofollow” checkbox. This adds a tag to that page and automatically excludes it from the XML sitemap.
How do breadcrumbs work?
Add the shortcode [clarity_seo_breadcrumbs] to your theme template or any page. Breadcrumbs include Schema.org BreadcrumbList markup and support page hierarchy and post categories.
Where can I find the XML sitemap?
Your sitemap is automatically available at yourdomain.com/sitemap.xml. It includes all public post types, taxonomy terms, images, and video/news tags. Noindexed pages are excluded.
Does this plugin store personal data?
The 404 monitor logs IP addresses and user agents for diagnostic purposes. This data is automatically cleaned up after 30 days and can be exported or cleared at any time from the 404 Monitor page.
Changelog
SERP preview in editor, SEO score column in post lists, one-click bulk meta generation, schema toggles, full Rank Math import, redirect manager UI. Sitemap excludes noindexed pages. Recommended for all users.
2.9.2 — 20 May 2026
- Hotfix: Fixed PHP Fatal Error in rank-tracker.php —
isset()was incorrectly wrapping asanitize_text_field()call (not allowed in PHP). Replaced with a clean$raw_kwsvariable check. This crash affected the rank-keyword save form on PHP 7.4+.
2.9.1 — 20 May 2026
- Review prompt now actually fires. Lowered the activation gate from 7 days + 3 engaged posts to 3 days + 1 engaged post OR 3+ admin page views. Existing users will see the prompt within 3 days of activation.
- Real success-event triggers wired up. The
clarity_seo_user_wonaction now fires automatically after Setup Wizard completion, first SEO Audit run, GSC connection, first Clarity meta save on any post, and on the 7th distinct admin page view (heavy explorers). - In-plugin email opt-in. A one-time, dismissible admin notice on Clarity pages invites users to receive the free AI SEO checklist and product updates. Pre-fills with the WP admin email. Posts to PluginJoy.com with full opt-out, no third-party scripts.
- Polished review notice. New PluginJoy purple gradient with ★ illustration, friendlier copy (“Is Clarity SEO helping?”), three clear actions (Leave 5-star review / I already reviewed / Maybe later).
- Daily-bucketed admin pageview counter. Counts at most one view per user per calendar day to avoid hot-reload inflation.
- Tested up to WordPress 6.9.4.
2.9.0
- NEW — Live Google Search Console dashboard via Site Kit: real keyword positions, impressions, clicks and CTR live inside Clarity. Detects Google’s free Site Kit plugin and pulls data automatically — no API keys, no OAuth setup.
- NEW — Search performance chart with date ranges: dual-line SVG chart of clicks + impressions over 7d / 28d / 3m / 6m / 12m / 16m, with ↑/↓ % deltas vs the previous period on every stat card.
- NEW — Free Rank Tracker: track 5 keywords daily. 30-day position history with sparkline per keyword. Reads from your Search Console connection automatically.
- NEW — Top Keywords / Pages / Countries tables inside the Search Console settings tab, all live data, cached 6h.
- NEW — Dual scoring system in every Gutenberg/Classic metabox — live SEO Score + AI Search Score (both 0-100) with checklist showing exactly what to fix.
- NEW — Live SERP preview: see your meta title and description rendered as a Google result while you type. Desktop / mobile toggle. Character counter goes green / orange / red.
- NEW — Closed-loop SEO audit: 30+ checks now scan your whole site (not just 10 recent posts). Every “Fix this” button filters the post list to exactly the posts that need work, with an explainer notice and a link back to the audit. Edit a post → save → re-audit shows the improvement.
- NEW — AI Search Score grades each post for ChatGPT / Claude / Gemini / Perplexity citation readiness — first SEO plugin on WordPress.org to do this.
- NEW — Conflict detector: warns you if Yoast / Rank Math / AIOSEO / SEOPress / Slim SEO / The SEO Framework / Squirrly is also active, so you don’t accidentally double up meta tags.
- Redesigned admin UI — every Clarity page now uses one unified hero, Clarity logo wings icon in the sidebar, indigo brand color throughout.
- Settings page now uses tabs — General · Schema & Local · Search Console · Redirects · 404 Monitor · Tools — same UX as the Pro section.
- Setup Wizard rewritten with a 3-step structure, Apple-clear form fields, and clear next-step CTAs on completion.
- Improved: Dashboard smart-status now reads “X of 6 things set up” with a live donut. Stat cards link directly into the right Settings tab.
- Fix: meta coverage no longer reports >100% on sites with revisions / autosaves; full-site stats are cached 1h and invalidate automatically when you save a post.
- Fix: Setup Wizard “complete” state was never recognised due to an option-name mismatch — banner now disappears after you finish the wizard.
- Performance: full plugin ships under 160KB zipped. No external JS libraries — every chart and widget is pure inline SVG.
2.8.7
- AI-search-era unlock: auto-generated /llms.txt endpoint (llmstxt.org standard) — your site is now discoverable by ChatGPT, Claude, Gemini and Perplexity without them having to crawl every page.
- AI crawler welcome: robots.txt now explicitly allows GPTBot, ClaudeBot, PerplexityBot, Google-Extended, Applebot-Extended and 7 more — filterable via
clarity_seo_allow_ai_crawlers. - Fix: duplicate canonical tag on every page — Clarity now properly removes WP core canonical so only one canonical URL is emitted (Google webmaster guideline compliance).
- Fix: duplicate sitemap conflict — disables WordPress 5.5+ core /wp-sitemap.xml when Clarity is active, so /sitemap.xml is canonical.
- Fix: meta keywords no longer leaks the page slug (“home”) when no explicit keywords are set — only outputs when there’s actual SEO value.
2.8.6
- Readme metadata cleanup — fix contributors order; optimized search tags for AI search era.
2.8.5
- New: v3 review prompt — usage-based trigger (3+ posts with Clarity meta) instead of pure timer.
- New: Subtle review prompt inside the post editor — most users live in Gutenberg, not on Clarity admin pages.
- New:
clarity_seo_user_wonaction — fires the review prompt right after a real success event (e.g. AI generate). - New: Backfill of activation_time for older installs that never recorded one — they now see the prompt.
- Improved: Direct 5-star review URL pre-selects the rating on WordPress.org, lowering friction.
- Improved: Review prompt now also shows on the post-edit screen, not only on Clarity SEO admin pages.
