Migrating from All in One SEO to Yoast SEO can be done safely, but it should not be treated as a casual plugin swap. Your titles, meta descriptions, canonical URLs, schema settings, sitemaps, and social metadata all contribute to how search engines understand your site. A careful migration helps preserve those signals and reduces the risk of ranking fluctuations.
TLDR: Back up your site, record your current SEO settings, then install Yoast SEO and use its import tool to bring over data from All in One SEO. After importing, verify titles, meta descriptions, canonical tags, sitemaps, redirects, and schema before removing the old plugin. Monitor Google Search Console and organic traffic closely for several weeks after the migration.
Why a Careful Migration Matters
SEO plugins do not directly “create” rankings, but they manage important technical and on-page elements. If those elements change unexpectedly, search engines may reassess pages, snippets may change, and indexing issues can appear. The goal of this migration is not only to move data from one plugin to another, but to ensure that search engines see your pages in the same or better condition than before.
Before starting, understand that some short-term movement in rankings can happen after any technical change. However, a properly planned migration should avoid major losses caused by missing metadata, duplicate tags, incorrect canonicals, or broken XML sitemaps.
Step 1: Create a Full Site Backup
Before changing SEO plugins, create a complete backup of your WordPress site. This should include both:
- Database: posts, pages, plugin settings, metadata, redirects, and SEO data.
- Files: themes, plugins, uploads, and configuration files.
If possible, perform the migration first on a staging site. A staging environment allows you to test the import, compare metadata, and identify conflicts without affecting your live website. If your hosting provider offers one-click staging, use it.
Step 2: Audit Your Current All in One SEO Setup
Do not rely only on memory or automated import tools. Before installing Yoast SEO, document your current All in One SEO configuration. Pay attention to:
- Homepage SEO title and meta description
- Post and page title templates
- Category, tag, and archive index settings
- Canonical URL behavior
- XML sitemap settings
- Social metadata for Facebook and X
- Schema markup settings
- Noindex rules for archives, media pages, or thin content
- Redirects, if you use All in One SEO for redirection management
This audit gives you a reliable reference point if something does not look right after the import. It is also wise to crawl your website using an SEO crawler before migration. Export the current titles, meta descriptions, canonicals, indexability status, and status codes. You can compare this file against a post-migration crawl.
Step 3: Install Yoast SEO Without Deleting All in One SEO Yet
Install and activate Yoast SEO, but do not immediately delete All in One SEO. In most cases, you should avoid having both plugins actively outputting metadata at the same time for long. Duplicate title tags, duplicate meta descriptions, or conflicting canonical tags can create confusion.
After activation, Yoast SEO usually detects data from other SEO plugins and offers an import option. You can also check the Yoast tools area for import functionality. Follow the import process from All in One SEO to Yoast SEO.
Once the import is complete, review a sample of important pages manually. Focus first on pages that drive revenue, leads, subscriptions, or significant organic traffic.
Step 4: Verify Imported SEO Titles and Meta Descriptions
The most visible part of the migration is usually the transfer of SEO titles and meta descriptions. Open several posts and pages in the WordPress editor and confirm that Yoast SEO populated the correct fields.
Check the following page types:
- Homepage
- Top traffic blog posts
- Main service or product pages
- Category pages
- Important landing pages
Small differences in title template formatting are common. For example, one plugin may use a different separator or site name structure. Minor formatting changes are not always harmful, but avoid accidental rewrites of high-performing titles unless you have a clear reason.

Step 5: Check Indexing and Noindex Rules
Indexing settings are critical. A mistake here can remove valuable pages from search results or expose pages that should remain hidden. Compare your old All in One SEO settings with Yoast SEO’s settings for content types, taxonomies, and archives.
In Yoast SEO, review whether search engines are allowed to show:
- Posts
- Pages
- Categories
- Tags
- Author archives
- Date archives
- Media attachment URLs
Many sites intentionally noindex tag archives, date archives, or media attachment pages to prevent thin or duplicate content. If those rules were active in All in One SEO, make sure Yoast SEO reflects the same strategy.
Step 6: Review Canonicals, Schema, and Social Metadata
Canonical tags tell search engines which version of a URL should be treated as the primary version. After migration, inspect several pages in the source code or with an SEO browser extension. Confirm that canonical URLs are present, correct, and not pointing to unexpected locations.
Next, review schema markup. Yoast SEO includes structured data features, but its output may differ from All in One SEO. Test important pages with Google’s Rich Results Test or Schema Markup Validator. Make sure organization details, breadcrumbs, articles, products, or local business data are still valid where relevant.
Also check social previews. If your site relies on custom Open Graph titles, descriptions, or images, confirm that Yoast imported them correctly. Social metadata may not directly determine rankings, but it affects how content appears when shared, which can influence engagement.
Step 7: Confirm XML Sitemaps
Yoast SEO generates its own XML sitemap. After switching, visit the Yoast sitemap URL and confirm that it loads correctly. Usually, it appears at:
/sitemap_index.xml
Check that the sitemap includes the correct post types and excludes anything that should not be indexed. Then update your sitemap submission in Google Search Console and Bing Webmaster Tools if the sitemap URL has changed.
Do not leave old sitemap references active if they are no longer valid. Broken or outdated sitemaps are not usually catastrophic, but they can slow discovery and create unnecessary crawl errors.
Step 8: Handle Redirects Carefully
If you used All in One SEO to manage redirects, check whether those redirects transfer to Yoast SEO. The free version of Yoast SEO does not include a full redirect manager, while Yoast SEO Premium does. If redirects do not transfer automatically, export them before disabling All in One SEO and import them into a reliable redirect plugin or Yoast Premium.
This step is especially important if you have changed URLs in the past. Losing redirects can create 404 errors, waste backlinks, and harm rankings for pages that previously depended on redirected authority.

Step 9: Disable All in One SEO and Test the Live Site
Once you have confirmed that Yoast SEO contains the necessary data, deactivate All in One SEO. Then test your website again. View the source code of key pages and make sure there is only one set of SEO meta tags. You should not see duplicate canonical tags, duplicate descriptions, or conflicting Open Graph data.
Run a fresh crawl of the site and compare it with your pre-migration crawl. Look for changes in:
- Page titles
- Meta descriptions
- Canonical URLs
- Noindex tags
- Status codes
- Internal links
- Sitemap URLs
If the crawl shows unexpected differences, fix them before assuming the migration is complete.
Step 10: Monitor Rankings, Traffic, and Search Console
After migration, monitor your site for at least two to four weeks. In Google Search Console, watch for indexing warnings, coverage changes, sitemap issues, and increases in 404 errors. In analytics, compare organic traffic to the same period before migration while accounting for seasonality.
Do not make unnecessary SEO changes immediately after the migration. If rankings move, you need a clean timeline to understand whether the plugin change caused the issue or whether another edit was responsible.
Final Checklist Before You Consider the Migration Complete
- Full backup created and stored safely
- All in One SEO settings documented
- Yoast SEO import completed
- Important titles and descriptions verified
- Noindex settings checked
- Canonicals reviewed
- Schema tested
- XML sitemap submitted
- Redirects preserved
- Post-migration crawl completed
Migrating from All in One SEO to Yoast SEO does not have to cost you rankings. The safest approach is methodical: document the old setup, import carefully, verify the output, and monitor the results. If you treat the migration as a technical SEO project rather than a simple plugin replacement, you can move to Yoast SEO with confidence and protect the search visibility your site has already earned.
