Coretex SEO is built for site owners tired of SEO plugins that flag problems without fixing them. Instead of showing red and green lights for missing meta descriptions or thin headings, it drafts the actual replacement text an editor would write, then holds every suggestion in a queue until someone approves it.
It suits anyone who wants SEO writing done for them, including people managing SEO across many posts or client sites.
The plugin does not run its own AI service. Instead, the site owner connects an account with an AI provider such as OpenAI, Anthropic, Google Gemini, Mistral, Groq, DeepSeek, xAI, Perplexity or OpenRouter, pasting in an API key so requests go directly from the site to that provider.
Ollama is also supported for running models on local hardware, which keeps content from leaving the server entirely. Suggestions generated this way appear in the plugin’s own Queue screen inside the WordPress dashboard, where nothing is published until it is reviewed and applied.

Key Features of Coretex SEO
Titles and meta descriptions. The plugin rewrites titles and meta descriptions for length and clarity rather than padding them to hit a character count, aiming for text that encourages clicks.
Heading structure review. It audits the H2 and H3 hierarchy of a page and proposes a revised outline that nests properly, helping pages read more logically for both visitors and search engines.
Internal linking suggestions. Coretex SEO scans existing content to find related posts and suggests anchor phrases to link them together, making it easier to build internal links without manual searching.
Image titles and alt text. It generates descriptive image titles and screen-reader-friendly alt text across the media library, improving accessibility and image search visibility.
Spelling and broken link checks. The plugin proofreads published posts for misspellings and checks every link on every published page, surfacing problems for the site owner to correct.
Duplicate and noindex detection. It identifies posts sharing the same title or description, and flags canonical or robots tags that are accidentally hiding pages from search results.
Content scoring and robots.txt editor. Every post and page receives a readability and optimization score, and a built-in robots.txt editor refuses to save changes that would deindex the entire site.
IndexNow and scheduled audits. Approved changes can be pushed to Bing and Yandex through IndexNow with a single click, and full site audits can be scheduled to run automatically with an email alert when problems appear.
How to Install Coretex SEO
Step 1: Install and activate. From the WordPress dashboard, go to Plugins > Add New Plugin, search for Coretex SEO, click Install Now, then Activate.
Step 2: Connect an AI provider. Go to Coretex SEO > Settings, choose an AI provider, paste in that provider’s API key, click Save Settings, then Test Connection.
Step 3: Add a site profile. Optionally fill in the Site Profile field so that generated suggestions match the site’s niche and tone.
Step 4: Run a scan. Go to Site Scans and start a scan to let the plugin review content and prepare suggestions.
Step 5: Review and apply. Open the Queue screen to read, edit, accept or discard each suggestion, and click Apply on the ones to publish.
Step 6: Note for Ollama users. If using Ollama, make sure the Ollama Server URL is reachable from the web server itself, since a localhost address only works when Ollama runs on that same server.
Good to Know About Coretex SEO
According to the plugin’s documentation, no account or license key is needed and it works fully on activation. An API key from a supported AI provider is required to generate suggestions, and the developer notes that these providers may charge for usage, except Ollama, which runs locally at no cost.
Content is sent only to the chosen provider, and only when a scan is run; with Ollama, nothing leaves the server. The developer also notes that the plugin writes to its own post meta and only outputs title and description tags if that option is switched on, so it can run alongside other SEO plugins without conflict.
