5. Main Stella SEO Page
The main Stella SEO page focuses on sitemap and core SEO settings.
Sitemap Settings
Exclude Post IDs

Example: 123, 456, 789
Sitemap Post Types
Select which post types should be included in the main WordPress sitemap output managed by Stella SEO.
Typical options include:
- Posts
- Pages
- Any public custom post types registered on the site
Sitemap Taxonomies
Select which taxonomies should be included in the sitemap. Typical examples:

- Custom taxonomies
Main Sitemap Fields
These options control which optional fields are added to the main sitemap URLs.
- lastmod: Adds the last modified date for URLs.
- changefreq: Adds a change frequency hint.
- priority: Adds a priority hint.
Note: Search engines may ignore some sitemap hints such as changefreq and priority, but the fields are available if you want to include them.
Change Frequency Map
If changefreq is enabled, you can define different values for:
- Home
- Post
- Taxonomy
Priority Map
If priority is enabled, you can define different values for:
- Home
- Post
- Taxonomy
Main XML Sitemap Link
The page also shows the main sitemap URL so you can open and verify it quickly.
Data Cleanup
This option controls whether Stella SEO removes its saved data when the plugin is uninstalled.
- Enabled: plugin data is deleted during uninstall
- Disabled: plugin data is preserved
When Pro is active: the uninstall behavior should respect the plugin split, so free and Pro data can be managed independently.
6. Pro Sitemap Builder
When Pro is active, additional sitemap controls are shown in the Stella SEO interface.
Product Sitemap
Creates a sitemap for WooCommerce or product-type content.
Optional fields may include:
- lastmod
- image
- title
- caption
Image Sitemap
Creates a sitemap for images found in eligible content.
Optional fields may include:
- lastmod
- title
- caption
Video Sitemap
Creates a video sitemap using required video fields for search engine compatibility.
Required fields are always included when video sitemap output is enabled.
Date Sitemap
Creates a date-based sitemap structure. This can help organize sitemap output by publication date.
User / Author Sitemap
Creates a user or author-based sitemap when enabled in Pro.
This is separate from the default WordPress user-related sitemap behavior and should only appear when the Pro feature is active.
News Sitemap
Creates a Google News style sitemap for eligible posts.
You can restrict this to selected categories so only news-eligible content appears.
Sitemap Links
Only enabled sitemap links should be shown in the UI. Disabled sitemap modules should not display public links.
7. Integrations & Tools Page
This page combines core technical features and utility tools.
Basic Site Schema
Enables baseline JSON-LD schema for:
- Organization
- WebSite
When Pro is active, advanced organization details can be overridden in the Pro schema tools.
Robots.txt Editor
Lets you manage custom robots.txt content where supported by the plugin workflow.
Use this carefully. A bad robots rule can block important content from crawling.
Auto Submit Sitemaps
When enabled, Stella SEO can notify supported services when new content is published and sitemap-related signals need refreshing.
IndexNow
IndexNow support can notify supported search engines about updated URLs. This typically requires an API key.
The plugin should explain where the key is needed and what the feature does.
LLMs.txt and LLMs-full.txt
These features help publish machine-readable guidance for AI systems and crawlers.
- llms.txt: concise, curated summary or index of important site content
- llms-full.txt: broader URL inventory, often with more links and configurable limits
llms.txt
Usually includes a concise intro and selected important URLs or content summaries.
llms-full.txt
Usually includes a much broader inventory. Related fields should only appear when the feature is enabled.
8. SEO Diagnostics
Stella SEO includes diagnostics to help identify optimization gaps.
Typical Checks
- Posts/pages missing SEO Title
- Posts/pages missing Meta Description
- Duplicate SEO titles
- Duplicate meta descriptions
- Broken canonical URLs
- Orphan pages/posts
View Posts / Quick Edit
For supported diagnostics, clicking the related action should open an inline management section so you can review items without leaving the page.
This view may include:
- ID
- Title
- SEO Title
- Meta Description
- Quick-edit style controls
- Pagination
Orphan Pages / Posts
An orphan page or post is content that exists on your site but is not well linked internally from other important pages.
This can affect SEO because search engines and users may have a harder time discovering it through normal site navigation.
Why It Matters
- Weaker internal link signals
- Lower discoverability
- Poorer crawl efficiency
- Missed ranking opportunities for useful content
How to Fix Orphan Content
- Add internal links from related pages or posts
- Include content in menus, hub pages, or category pages
- Link from cornerstone or high-authority pages
- Review whether low-value orphan pages should stay indexed
9. AI Visibility Checklist
This checklist summarizes key signals that help search engines and AI systems understand your content.
Typical Signals Reviewed
- SEO title coverage
- Meta description coverage
- Structured data baseline
- Sitemap discoverability
- Robots safety
- AI optimization pipeline
- Fast indexing signals
- Advanced structured data coverage
- Specialized sitemap coverage
- Multilingual context signals
Statuses may include:
- PASS
- WARNING
- NEEDS WORK
10. Bulk Editor
The bulk editor is designed to help you review and update SEO metadata across many posts or pages from one screen.
Typical Fields
- Post ID

Pagination
The bulk editor should use pagination or soft-pagination style controls so large datasets remain manageable.
11. CSV Import and Export
Pro includes CSV export and import workflows for bulk SEO updates.
Export SEO Data
Exports metadata fields such as:
- post_id
- title
- seo_title
- seo_description
- focus_keyword

Import SEO Data
The import flow should analyze the CSV before applying changes.
Expected Review States

- ID Mismatch: title matches but CSV ID does not match the current system ID
- Skipped: invalid or non-importable row
Recommended Workflow
- Upload CSV
- Analyze CSV
- Review conflicts
- Import safe rows only, or choose override options for conflicts
Conflict review tables should clearly separate:

Differences should be easy to compare line by line.

Pro includes a redirect manager for mapping outdated URLs to new targets.
Common Fields
- Source URL
- Target URL

- Add API key
- Fetch models
- Select a model
- Check connection

Typical Provider Support
- OpenAI
- Claude

The plugin should clearly explain what provider is selected, where to add the API key, how to fetch models, and how to verify the connection.
18. User Guide / Help
Stella SEO can include a help panel or contextual documentation in the admin interface. This is useful for explaining each field directly where users need it.
A good help section should explain:
- What each setting does
- When to enable or disable it
- Whether the field is optional or required
- Whether the feature is free or Pro
19. Common Troubleshooting
My meta description did not change on the frontend
Check whether the SEO Meta Description field in the metabox already has a saved value. If it does, that value overrides fallback content such as the excerpt or post content.
My social description is not syncing
If sync is enabled, editing the SEO title and meta description should update the social title and description automatically. If it does not, check that the sync option is enabled and that the metabox JavaScript is loading correctly.
Why does a sitemap link return 404?
Make sure the sitemap type is enabled. Disabled sitemap modules should not be expected to resolve. If needed, refresh permalinks in WordPress.
Why is a logo not appearing in schema?
The plugin uses available logo sources such as schema override, site icon, or custom logo depending on the configuration. If no valid logo URL is found, the logo field should be omitted from schema.
Why are some values not showing in import conflict review?
Check whether the imported row is a duplicate, conflict, or ID mismatch. ID mismatch rows should compare against the current system post even if the CSV post ID is different.
20. Best Practices
- Write unique SEO titles for important landing pages
- Write meaningful meta descriptions instead of relying on auto-generated excerpts
- Use noindex carefully; do not noindex valuable pages by mistake
- Keep your sitemap focused on indexable, useful URLs
- Use redirects when changing permanent URLs
- Add FAQ or HowTo schema only when the page genuinely contains that content
- Use LocalBusiness schema only when it accurately describes your organization
- Review diagnostics regularly to catch missing metadata and orphan content
21. Support Workflow
When troubleshooting Stella SEO, start with this order:
- Check plugin settings
- Check the post/page metabox fields
- Check generated source output
- Check sitemap URLs
- Check diagnostics and bulk tools
- Clear site and browser cache if output appears stale
22. Final Notes
Stella SEO is designed so that the free plugin provides the shared core SEO experience, while the Pro plugin extends the same admin workflow with advanced tools. This keeps the interface familiar while allowing you to scale from simple on-page SEO to more advanced sitemap, schema, AI, redirect, and bulk SEO workflows.
