The WordPress SEO plugin that doesn't rent itself to you.

Changes in version 6.0.1:

• Fixed: Signocore SEO now updates itself when automatic updates are turned on, so new versions are installed without you having to click Update.
• Fixed: The "Enable auto-updates" link for Signocore SEO now shows on the Plugins screen, even when no update is waiting.

Version 6.0.0:

• Added: Breadcrumbs now cover date archives and custom post type archive pages, so visitors and search engines can follow the full path.
• Added: Title and description templates for custom post type archive pages, which now also get a proper title of their own.
• Added: Choose a primary category for products. It decides which category appears in the product's address, breadcrumbs and structured data.
• Added: Choose whether AI companies may train their models on your content, and whether AI assistants such as ChatGPT and Perplexity may use your pages in their answers, straight from the robots.txt settings.
• Added: Settings for PDF files and the REST API in robots.txt, so PDFs you want found in search can be opened up and shop blocks that load products can show up in Google.
• Added: An Attachment Pages setting that controls whether uploaded files get pages of their own. While they are off, Pro sends visitors to the post a file belongs to.
• Added: Company details for structured data: legal name, alternate name, founding date, number of employees and business identifiers (D-U-N-S, LEI and GLN). Only the fields you fill in are used.
• Added: Site verification for Ahrefs Webmaster Tools.
• Added: New SEO Health checks: primary keyword in the introduction, alt text on images and at least one internal link.
• Added: A readability tip points out paragraphs longer than 150 words.
• Added: The primary keyword field shows other pages that already use the same keyword.
• Added: A "Missing alt text" filter in the media library list view.
• Added: A notice when another plugin adds a new content type, with a link to review its search engine settings.
• Added: Extra keyphrases from Yoast SEO Premium and All in One SEO are imported as secondary keywords.
• Added: The author archive address can now be changed under Settings > Permalinks.
• Added: A Documentation link on the Plugins screen that opens the online guides.
• Added: The Shortcodes card in the settings now also explains how to add a table of contents.
• Added: Pages and categories that get a new address keep their old address working, including the pages below them. (Pro)
• Added: When you trash or delete published content, a notice offers to redirect its old address or tell search engines it is gone for good. (Pro)
• Added: A "Create redirect" link in the admin bar on "page not found" pages. (Pro)
• Added: Bring your redirects along from Yoast SEO Premium, Rank Math, Redirection and All in One SEO on the Import page, with a clear list of any rules you need to recreate by hand. While Redirection is active, you are reminded to import its redirects and to switch it off afterwards, so two sets of redirect rules never compete. (Pro)
• Added: Choose which Claude model writes your SEO fields (Claude Haiku 4.5, Sonnet 5.5 or Opus 5.5) and which writes your content (Claude Sonnet 5.5 or Opus 5.5). New sites start with Claude Sonnet 5.5 for both, while sites updating from an earlier version keep Claude Haiku 4.5 for SEO fields and can switch at any time in the AI settings. (Pro)
• Added: Generate Content now follows the outline in the editor, so an outline from Generate Outline, with your own adjustments, shapes the finished article, and you are asked before either button replaces other text in the editor. (Pro)
• Improved: Signocore SEO now requires PHP 8.1 and WordPress 6.9 or newer. Sites that do not meet this are not offered the update and keep working on their current version.
• Improved: Below PHP 8.2, a notice tells you in good time that the next major version, planned for February 1, 2027, will need PHP 8.2.
• Improved: Signocore SEO has a new design in the Signocore style. The dashboard, settings, Bulk Editor, redirects, Image Generator, import, 404 and SEO Health screens and the SEO box in the editor share one calm, consistent look, and the screens adapt to phones as well as desktops.
• Improved: Clearer typography throughout, using the Signocore fonts that ship inside the plugin.
• Improved: The plugin's styles and scripts now load only on the screens that use them, so the rest of the admin is lighter.
• Improved: Pro features are clearly marked in the free version, including internal links, orphaned pages, extra schema types, advanced schema, llms.txt and automatic alt text, each with a short overview of what you get.
• Improved: The dashboard leads with your keyword coverage and shows how much of your content each gap affects.
• Improved: Your sitemap, search engine tags and structured data update as soon as content changes, whether you save in the editor, use Quick Edit, move a post to the trash, publish on a schedule, change a menu or your site name, or when WooCommerce changes a price or stock level. Nothing is left waiting for up to a day or a week, and ordinary page views do no extra work.
• Improved: Sitemaps are built with far fewer database queries, which helps large sites, and they list your images at full size.
• Improved: On multilingual sites, each language's sitemap leaves out content types that have nothing in that language.
• Improved: After an update, titles, sitemaps, breadcrumbs and llms.txt refresh right away.
• Improved: Saving is faster, because IndexNow is notified with a single request that all participating search engines share, and scheduled posts are sent when they go live.
• Improved: Search engines are told through IndexNow when a page is unpublished, trashed or moved, so old addresses drop out sooner.
• Improved: "Request Indexing" now tells you whether the request succeeded.
• Improved: Keyword checks match from the start of a word, so "art" no longer counts as found in "start", while word endings such as "huset" and forms such as "SEO-plugin" still count.
• Improved: Readability for Danish, Swedish and Norwegian content uses LIX, the Scandinavian standard, for more accurate levels and reading times.
• Improved: The automatic description starts at the paragraph that mentions your primary keyword, which is what searchers look for.
• Improved: Your pages state their language without a country, for example "da" instead of "da-DK", so search engines such as Bing do not tie them to one country. Chinese and sites with two variants of one language keep the country, and the setting can be turned off.
• Improved: Social sharing tags state your site's language on every site, show a share card also for pages without an image, and link to the author's Facebook profile when one is set.
• Improved: Cleaner structured data: WooCommerce category images are included, your site tagline is used when no home page description is set, front pages that list your latest posts get their own page entry, and the company address waits until a country is chosen.
• Improved: Structured data describes every page with the same description as its search result, names the category of each article, shows each author's own profile picture, and keeps article and category lists short and fast.
• Improved: WordPress' default tagline "Just another WordPress site" is no longer used in structured data, descriptions or llms.txt.
• Improved: Products hidden from your shop catalog are hidden from search engines too, and left out of the sitemap, llms.txt and IndexNow. Products shown in search results only stay visible.
• Improved: Author pages with no posts and no biography, such as those of shop customers, are hidden from search engines, while author profiles with text stay visible.
• Improved: New customer accounts, for example from WooCommerce checkout, no longer slow the site down and keep their standard profile address. Only people who write posts get a name-based author address.
• Improved: Comment feeds are kept out of search results, and feeds for categories or tags that do not exist return "not found" instead of an empty feed.
• Improved: Social sharing tags on articles name your Facebook page as the publisher, when you have added one.
• Improved: The Twitter setting is now called X Username.
• Improved: The settings show when llms.txt, advanced schema and automatic alt text are active, with a direct link to your llms.txt file. (Pro)
• Improved: Each page in llms.txt is described by its own description instead of repeating its title, and each language gets its own list. (Pro)
• Improved: Renamed posts keep their old address working with any permalink setting, and the redirect shows up in the Redirect Manager, where you can see, count and edit it. (Pro)
• Improved: Redirects keep tracking parameters such as utm_source when they send visitors on. (Pro)
• Improved: Addresses set to "410 Gone" use your theme's 410 template when it has one, and otherwise look like your normal "not found" page. (Pro)
• Improved: Redirects are found faster on sites with many redirects, and hit counts stay exact on busy sites. (Pro)
• Improved: The 404 list shows the best matching page up front, with other suggestions in a small menu. (Pro)
• Improved: The 404 log now stays within its 5,000-entry limit at all times. (Pro)
• Improved: The TL;DR summary now reads the whole post instead of only the opening, so it also reflects long articles. (Pro)
• Improved: Clear messages when Claude declines a request or runs out of room, an unfinished article is marked as unfinished, and Generate All and the Bulk Editor show the reason your AI provider gives when something fails, or tell you when the service is temporarily unavailable. Claude Sonnet 5.5 and Opus 5.5 get more room, so outlines and articles are finished instead of cut off. (Pro)
• Improved: Automatic alt text now also covers images uploaded in the block editor and AI images, keeps alt text an image already has, and is explained clearly in the settings: it is built from the image title. (Pro)
• Improved: Variable products are described with the right price for the variation a visitor opens, using the attribute names shoppers see, so shopping feeds see the price the page shows. (Pro)
• Fixed: Password-protected posts no longer reveal their text in descriptions, social sharing tags or structured data, their featured image is not shared, and they are left out of the sitemap, llms.txt and IndexNow.
• Fixed: Structured data now appears on new sites right away, without saving a settings page first.
• Fixed: Pages hidden from search engines no longer name a preferred address or neighboring pages, which sent search engines mixed signals.
• Fixed: Parent categories whose products or posts sit in subcategories are no longer hidden from search engines.
• Fixed: Posts split into several pages give every page its own address and title, so search engines can find the later pages.
• Fixed: Update dates are never earlier than the publishing date, also for scheduled posts, and the sitemap index shows when each sitemap last changed.
• Fixed: Sitemap images keep working after a move to a new domain or to https, and only images a page really shows are listed.
• Fixed: Structured data always names the page's own address, also after search engines visit addresses that combine several tags. Such combined tag and category pages are now hidden from search engines.
• Fixed: Reply links in comments are kept out of search results again.
• Fixed: The primary category only applies while a post is still in that category, and embeds, later pages and comment pages of posts in several categories open correctly instead of jumping to the first page. Links in the admin and IndexNow use the same address as your visitors.
• Fixed: robots.txt keeps the rules other plugins add, such as WooCommerce's rules for add-to-cart links.
• Fixed: "Exclude noindexed posts from search" only affects your site's search page, so the link search in the editor finds every post again.
• Fixed: Translated cart, checkout and account pages are hidden from search engines like the originals.
• Fixed: Page 2 and later of date archives name the right address.
• Fixed: The unique title and unique description checks now find duplicates the same way the Dashboard does.
• Fixed: The keyword-in-address check no longer fails forever for blog posts when the permalink structure has no post name.
• Fixed: Secondary keywords with letters such as æ, ø and å are now found in subheadings.
• Fixed: The reading time shortcode updates as soon as a post changes.
• Fixed: New WebP and AVIF images get a JPEG social image, or a PNG when they are transparent, so LinkedIn shows them.
• Fixed: AI features now work on servers without the PHP intl extension.
• Fixed: Changes made in the block editor now notify IndexNow too, and pages whose preferred address is elsewhere are no longer sent.
• Fixed: Noindex rules for post types, taxonomies, empty archives and other archives now apply straight away, without saving each post or the settings first.
• Fixed: Saving a page, post or category that is hidden from search engines automatically, such as an empty category, no longer keeps it hidden once the reason is gone.
• Fixed: Categories and tags without their own title or template get their automatic title right away.
• Fixed: SEO settings now appear on WooCommerce product categories, FAQ categories and other custom categories.
• Fixed: Posts you keep indexed inside a hidden post type now appear in the sitemap and in site search.
• Fixed: The Home Page SEO settings are shown whenever your front page lists your latest posts.
• Fixed: Placeholders such as %%date%% and %%category%% are kept when you save the SEO box or the Bulk Editor, or apply AI suggestions, work no matter how they are capitalized, and %%category%% uses the primary category.
• Fixed: Importing from Yoast SEO now brings over the settings of all your posts and categories, also when Yoast never finished indexing your site, keeps your index settings and the primary categories of posts and products, and no longer turns post titles into breadcrumb titles or featured images into social images.
• Fixed: Focus keywords from Rank Math and SEOPress are split into a primary keyword and secondary keywords, running the import again corrects keywords from an earlier import, and Rank Math's primary product categories come along.
• Fixed: Imports from SEOPress keep indexed content visible to search engines, imports from All in One SEO keep placeholders in titles, and the import no longer stops early and shows the correct progress.
• Fixed: Web addresses with characters like é, ñ and ü are kept exactly as written in search engine tags and structured data.
• Fixed: Addresses opened with tracking parameters such as utm_source are cleaned before they reach search engine tags and structured data.

• Fixed: Product prices shared on social media now include the correct currency.
• Fixed: If a chosen social image has been deleted, your featured image or default social image is shown instead of no image.
• Fixed: On multilingual sites, saving one language keeps your main language intact, empty fields fall back to the main language, and company details, home page SEO, templates, breadcrumbs and the site menu in structured data follow the language of the page.
• Fixed: Author pages on multilingual sites open correctly.
• Fixed: With Polylang, the Languages settings page opens again, translated search and pagination addresses work, categories that share a slug across languages work, and language sitemaps work on sites that keep /language/ in their addresses.
• Fixed: Product breadcrumbs show the product's category, also when the product address has none, post breadcrumbs follow the category in the address, and names with characters like "&" display correctly.
• Fixed: Saving a category or tag also refreshes the breadcrumbs of every post in it.
• Fixed: On a network, each site keeps its own titles, sitemaps, breadcrumbs, dashboard figures and license status.
• Fixed: The table of contents shortcode looks and scrolls like the block, several tables of contents on one post keep their own settings, and links work for headings with special characters.
• Fixed: Posts duplicated with Signocore Clone get their own SEO address, link data and IndexNow status instead of the original's.
• Fixed: Picking an image fills the field you clicked, and the social preview updates the moment you choose or remove one.
• Fixed: An expired session shows a readable message instead of a loader that never stops.
• Fixed: AI and preview messages appear in your site's language.
• Fixed: The "Settings saved" message can be dismissed.

• Fixed: SEO Health now scores the meta description that visitors and search engines actually see, including descriptions filled in from your templates or created automatically.
• Fixed: Broken links that visitors reach from Google search results now show up in the 404 log, so you can redirect them. (Pro)
• Fixed: Redirects from addresses with a query string, such as /old-page/?id=5, now work, including redirects created from the 404 log. (Pro)
• Fixed: Redirects created from the 404 list work on sites installed in a subfolder. (Pro)
• Fixed: A redirect that points to its own address is switched off instead of sending visitors in a loop. (Pro)
• Fixed: Redirects to lowercase addresses keep the trailing slash and the language folder, so visitors arrive in one step. (Pro)
• Fixed: Attachment pages go to the file itself when they do not belong to a public post, instead of the home page, and the attachment redirect works again on newer WordPress installs. (Pro)
• Fixed: With WPML, the redirect that corrects the blog address keeps special characters and the query string intact. (Pro)
• Fixed: AI buttons on author profiles work with a Pro license. (Pro)
• Fixed: A social or featured image made with AI in the SEO box shows up right away when the page is shared, also before you save the post. (Pro)

• Security: Every setting is checked field by field before it is stored.
