Ai0 Content Refresh

AI-assisted SEO improvements and ongoing maintenance for existing WordPress content.

Ai0 Content Refresh reviews pages and blog posts you have already written. It uses your chosen OpenAI model to propose clearer writing, better structure and useful additions while preserving Gutenberg layouts, images, videos, banners and links. A complete history lets you inspect changes, publish proposals and restore previous content.

What it does

• Improve existing text: clearer introductions, readability, grammar and explanations without inventing new facts.
• Add useful content: summaries, FAQs, checklists, comparison tables, callouts and relevant internal links. At most four plugin text elements per page in total.
• Reuse your images: search the WordPress media library, provide metadata for up to 12 relevant candidates and add at most two native Gutenberg image blocks. Image files are not sent to OpenAI.
• Prioritize reviews: use Google Search Console, the built-in view counter or both, alongside manual priorities, Yoast cornerstone markers, search opportunities and content age.
• Schedule work: choose a monthly start day, hour, generation limit and token limit. Save proposals for review or publish automatically after technical validation. Automation is off initially.
• Enforce a six-month cooldown: a page is eligible only six calendar months after its latest publication or content modification, including manual edits and content updates by this plugin.
• Estimate costs: forecasts before generation and token-based estimates afterwards, with automatic USD/DKK conversion using dated Frankfurter/ECB rates. Custom model rates are supported.
• Keep a review history: before/after differences, model, saved prompt, token usage, image choices, reasons and status. Direct links open the public page and WordPress editor. Restore is blocked if the content has changed since.
• Exclude content: a searchable selection list shared with the editor. Privacy policy pages, password-protected content and Yoast noindex pages are excluded automatically.
• Use your preferred interface language: English source strings with bundled Danish PHP and JavaScript translations. The interface follows the WordPress user's language; untranslated locales fall back to English. Existing custom prompts and content are preserved.
• Receive WordPress updates from GitHub: version 1.5.0 and later integrate with the native plugin update screen. No GitHub token is required for this public repository.

The SEO goal is useful, relevant and well-maintained content. The plugin changes post_content; titles, URLs, categories, featured images, Yoast fields and theme metadata are preserved. It does not perform external research or fact-checking, and it cannot guarantee higher rankings. FAQ elements do not promise FAQ schema or rich results. Technical validation checks format, preservation and permitted images. Review the first proposals, particularly pages with prices, guarantees or other important factual claims.

Requirements and compatibility

Minimum requirements are not a complete compatibility matrix. Local validation used PHP 8.5.2 and WordPress 7.1.3, including the official WordPress SQLite compatibility layer. Production publishing requires InnoDB. See TESTING.md for evidence and limitations.

Installation

1. Download ai0-content-refresh-1.5.0.zip from the latest release. Choose the named installation asset, rather than GitHub's generated source archive.
2. In WordPress, open Plugins → Add New Plugin → Upload Plugin, upload the ZIP and activate it.
3. Open Content Refresh → Settings, enter your OpenAI API key and save.
4. Click Test key and retrieve models. Choose a compatible text model from the dropdown or enter an ID under Other model. The list includes all account model names, including models unsuitable for generation.
5. Configure the prompt, content types, exclusions, media access, traffic source and usage limits.
6. Generate a proposal for an eligible page and inspect its history, changes and image choices.
7. Enable scheduled reviews when ready. Manual generations always save proposals.

The recommendation is a starting point, subject to model availability and your own review. New installations use an English editorial prompt that preserves the article's existing language. Updating the interface does not translate articles or replace existing saved prompts.

Google Search Console

The optional connection uses Google login after a one-time setup of your own OAuth client in Google Cloud. Enable Search Console API, configure read-only consent, create a Web application client and copy the exact redirect URI shown in Settings. Save the Client ID/Secret, connect Google and select a property covering this site.

The plugin compares two 28-day periods with a three-day delay; data older than seven days is ignored in priorities. Missing rows do not prove zero traffic. Google clicks measure organic search clicks, rather than all website visits. There is no shared hosted login service or shared Google secret. Testing-mode OAuth apps may require frequent reconnection; Google's publishing and verification rules still apply.

Built-in view counter

The counter shows 90 days / 1 year, starting at installation. It excludes all logged-in users, including on cached pages, plus known bots and previews. It respects DNT/GPC and sets no tracking cookies. Stored data contains a date, content ID and count; a short-lived abuse limit uses a one-way value derived from the IP address. Data older than one calendar year is removed on upgrade and daily through a separate WP-Cron job. Generation history is retained.

Counts are approximate and are not unique visitors. Clear WordPress/CDN caches after installation, upgrades or tracking changes. The website owner determines consent requirements; ai0r_tracking_allowed supports local integration. See readme.txt for details.

Updates and versions

Upgrade from 1.0–1.4: install the 1.5.0 ZIP once using WordPress' replace-existing-plugin flow. Older versions do not contain an update client and therefore cannot discover this first upgrade themselves. Settings, encrypted credentials, custom prompts and history are retained.

After installing 1.5.0: WordPress checks this repository's latest stable release and uses the named plugin ZIP and matching update.json compatibility manifest. Checks are cached for six hours; opening Dashboard → Updates clears the plugin's cache for a fresh WordPress check. Failures are retried after a short delay. Drafts, prereleases, foreign packages and mismatched metadata are ignored. GitHub's public API limits can delay discovery.

New versions appear in Plugins / Dashboard → Updates. WordPress keeps the administrator's existing auto-update preference; this plugin does not enable auto-updates for you. To install future releases automatically, use WordPress' normal Enable auto-updates control. Content-review automation is a separate setting.

Each release has a Git tag, release notes and installation asset. Historical 1.0–1.4 ZIP files remain unchanged, with their original Danish interface. Cost estimates exclude VAT, fees and negotiated discounts; the API invoice is authoritative. Historic rates and exchange observations are not recalculated.

Languages and contributions

The source language is English. Danish (da_DK) is bundled in languages/ as PO/MO and WordPress JavaScript JSON catalogues. A POT template is provided for additional languages. Choose a language under Users → Profile → Language, or use the site default under Settings → General. Frontend labels use the site's locale. Changing interface language does not rewrite saved history or prompts.

Translators can edit the PO file in Poedit or another gettext editor, compile the MO, and produce JSON catalogues for ai0r-admin and ai0r-block. The text domain is ai0-content-refresh. Keep %s, %d and numbered placeholders intact. See languages/README.md.

Data and external services

Generation sends the selected page's text, title, URL, editorial prompt, a bounded list of public internal links and optional image metadata to OpenAI with store=false. Image files and raw view counts are not sent. Credentials and Google tokens are encrypted with a key derived from WordPress salts; changing salts requires reconfiguration.

Frankfurter/ECB provides exchange rates without a key. Google is used after configuration and consent. Update checks contact GitHub's public release API and download a small compatibility manifest; they send a plugin-version user agent and normal server network information, with no OpenAI key, Google token, article content or view statistics. No GitHub credentials are needed. See readme.txt for endpoints, limits and developer hooks.

Validation

Version 1.5.0 passed 76 regression checks, 107 WordPress integration checks and 33 language/update checks locally, plus PHP and JavaScript syntax checks. The update suite exercises WordPress core's actual update discovery, English/Danish switching and JavaScript catalogues. OpenAI, Google and update-service responses were simulated; this is not a live-model quality evaluation or Elementor test. Earlier public currency access was also verified through WordPress.
