SEO plugins set your tags. They do not tell you about the duplicate tag pages, broken links, canonical conflicts and slow Core Web Vitals that pile up on a real WordPress site. Our WordPress SEO audit crawls your whole site and finds them, no plugin to install. First audit free, then $9 one-time.
Instant, free, no plugin, no signup - we check your homepage on the spot.
WordPress is flexible, and that flexibility quietly creates technical SEO problems as a site grows. These are the ones an audit catches.
Tag, category, author and date archives can create thin, near-duplicate pages that compete with your real content.
Renaming posts, changing permalinks or deleting pages leaves broken internal links and lost backlinks behind.
Themes and plugins can emit conflicting or missing canonicals, splitting your ranking signals.
Image attachment pages and unmanaged pagination create low-value URLs that should be redirected or controlled.
Render-blocking scripts and styles from plugins and themes drag down Core Web Vitals.
A stray noindex, a robots rule, or a staging setting left on can quietly keep pages out of Google.
You want both. Here is the split.
It helps you write titles and meta descriptions, set canonicals and add schema as you create content. It works page by page, inside the editor, based on what you tell it.
It crawls the live, rendered site and reports what actually happened across every page: the broken link on an old post, the duplicate archive nobody noindexed, the canonical the theme overrode, the page that got slow. It finds the gap between how the site was configured and how it really behaves.
Confirm ownership with DNS, a meta tag, or a file upload. No plugin needed.
We crawl every page against 180+ technical checks plus PageSpeed.
Issues are grouped so you can fix the root cause once, often at the theme or template level.
Nothing gets installed. Kalenux crawls your live site from the outside, so there is no plugin adding queries or scripts to a site you are trying to keep fast, and no compatibility question with your existing stack.
It works alongside an SEO plugin rather than replacing one. The plugin configures tags as you write; the audit checks how the whole rendered site behaves once the theme, the plugins and years of published content have all had their effect.
Duplicate or thin archive pages from tags, categories, authors and dates; broken links left by renamed posts, changed permalinks or deleted pages; missing or conflicting canonicals emitted by themes and plugins; pagination and image attachment pages that should be redirected or controlled; render-blocking plugin and theme assets; and slow Core Web Vitals. That is across 80-plus checks plus real PageSpeed measurement.
They do different jobs, and you want both. A plugin like Yoast or Rank Math helps you set titles, descriptions, canonicals and schema page by page inside the editor, based on what you tell it. The audit crawls the finished, live site and reports what actually happened: the broken link on an old post, the duplicate archive nobody noindexed, the canonical the theme overrode, the page that quietly got slow. Use the plugin to configure and the audit to verify.
Your first full-site audit is free, then $9 one-time, with no subscription and credits that never expire. You can also run an instant single-page check with no account if you want to see the output before signing up.
Almost every WordPress site already runs an SEO plugin, which makes the obvious question a fair one: if the plugin is installed and its lights are green, what is left to audit. The answer is that a plugin and a crawler look at different things, and the gap between them is where WordPress sites usually break.
SEO plugins are editorial assistants. They live inside the admin and evaluate the post in front of you: is there a focus keyword, is the title a reasonable length, is there a meta description, does the content use subheadings. They also emit the tags your theme would otherwise omit, which is genuinely valuable and is why they are near-universal.
All of that is scoped to one post at a time, at the moment you are editing it. The plugin does not request your pages over HTTP, so it does not see what a visitor or a crawler actually receives.
The faults that damage WordPress sites are mostly relational or served rather than authored. Tag and category archives multiplying near-duplicate listings. Attachment pages published as standalone URLs. Paginated archives with identical titles. Broken internal links pointing at posts whose slugs changed. Redirect chains accumulated across plugin migrations. A caching or security plugin adding a header the theme never intended.
None of these appear in a per-post editorial check, because none of them are properties of a post. They are properties of the site as a whole, or of what the server sends when a URL is requested, and finding them requires fetching the pages from outside WordPress the way a search engine does.
WordPress sites accumulate plugins that each believe they own part of the head. Two SEO plugins active at once emit two canonical tags. A migration tool leaves a sitemap behind while the current plugin generates another, so two sitemaps disagree about what exists. A caching layer serves a stale version of a page whose tags were fixed weeks ago.
Each plugin reports itself as working, because from inside its own admin screen it is. The contradiction only exists in the response the server actually sends, which is precisely what a crawl reads and what an admin panel never sees.
The productive arrangement is not choosing between them. Keep the plugin for what it does well: per-post guidance while writing, and emitting tags your theme lacks. Add a crawl for what it structurally cannot do: comparing pages against each other, following links across the whole site, and reading what visitors actually receive rather than what the editor intended.
