Most ranking losses during a platform migration come from one cause: URLs changing without redirects. Everything else, including losing content, metadata, and internal links, is recoverable with effort. Broken URL continuity is what turns a migration into a lasting decline, and it is entirely preventable with an inventory taken before anything is touched.
Why people leave page builders
Usually some combination of weight, cost, and inflexibility. Builders generate a great deal of markup and load substantial scripts, which shows in performance. Licensing recurs. And content ends up in proprietary structures that are difficult to extract, which is the lock-in that eventually prompts the move.
Those are legitimate reasons. The migration is also the moment of highest risk to search visibility, so it deserves more planning than the decision itself.
Inventory first, before touching anything
This is the step that determines whether the migration succeeds, and it is done while the old site is still live and intact.
- Crawl the entire existing site and export every URL. Not the ones you remember, all of them.
- Export Search Console data for the last twelve months, so you know which URLs actually receive impressions and clicks. This tells you what must survive.
- Record the title and meta description of every page, since these are routinely regenerated by the new system and quietly lost.
- Record heading structure and internal links. Internal linking is rebuilt badly more often than it is preserved.
- List every image and file, including PDFs, which are frequently forgotten and frequently linked externally.
- Note any pages already redirecting. Old redirects need carrying forward, or you break a chain that was working.
- Take a full backup you have verified you can restore.
Preserve the URLs if you possibly can
The simplest successful migration changes nothing about the addresses. If every page keeps its URL, most of the risk disappears at once.
Where the new platform imposes a different structure, resist accepting its defaults. Most systems can be configured to match an existing pattern, and doing so is far cheaper than managing redirects forever.
If URLs genuinely must change, then every old URL needs a permanent redirect to its closest equivalent. Specifically:
- Map one to one wherever a direct equivalent exists.
- Avoid redirecting everything to the homepage. It is treated as a soft error and it discards the value of the original page.
- Use permanent rather than temporary redirects for moves that are permanent.
- Avoid chains. Old to new directly, not old to interim to new.
What else gets lost
Metadata
New platforms generate titles and descriptions from templates. Pages that had carefully written ones end up with a pattern. This is why the inventory matters.
Structured data
Markup implemented in the old system rarely transfers automatically and needs rebuilding deliberately.
Content that existed only inside the builder
Text held in proprietary modules can be absent from any straightforward export. Pages then arrive on the new site subtly thinner than before, which is difficult to spot without the inventory.
Images and alt text
Frequently re-uploaded to new paths, breaking existing image references and losing alt attributes.
Launch and the weeks after
- Check the staging site is not blocking crawlers before it goes live. Development sites are routinely blocked to keep them out of search, and the block is routinely carried into production. It is the most damaging single mistake in this whole area and the easiest to prevent.
- Crawl the new site immediately and compare against the inventory. Every URL should either exist or redirect.
- Test a sample of old URLs by hand, including deep ones nobody thinks about.
- Submit the new sitemap and keep the old one available briefly so the redirects are discovered.
- Watch coverage and crawl errors for several weeks, not days.
- Expect a dip. Some fluctuation is normal while everything is recrawled and reassessed. Judge the outcome at four to six weeks rather than four to six days.
The dip is worth emphasising, because it is where migrations get abandoned halfway. A partial reversal usually leaves a site in a worse position than either completing or never starting.
Frequently asked questions
Will migrating off a page builder hurt my rankings?
It can, and the main cause is URLs changing without redirects. If addresses are preserved, most of the risk disappears. Where they must change, every old URL needs a permanent redirect to its closest equivalent for visibility to carry across.
What should I do before starting a migration?
Crawl and export every existing URL, export twelve months of Search Console data to identify which pages actually receive traffic, record titles, meta descriptions, heading structure, internal links, images and files, note existing redirects, and take a verified backup.
Should I redirect old pages to the homepage?
No. Redirecting many pages to the homepage is generally treated as a soft error and discards the value of the original page. Each old URL should point to its closest genuine equivalent, and pages with no equivalent need a considered decision rather than a blanket rule.
What is the most damaging mistake during a site migration?
Launching with the crawler block that was applied to the staging site still in place. Development sites are routinely blocked from search, and carrying that block into production removes the site from results entirely until someone notices.
How long should I wait before judging a migration?
Four to six weeks. Some fluctuation is normal while pages are recrawled and reassessed, and judging the result after a few days often prompts a partial reversal that leaves the site worse off than either finishing or never starting.
What gets lost in a migration besides URLs?
Meta titles and descriptions regenerated from templates, structured data that does not transfer automatically, content held inside proprietary builder modules that does not appear in exports, and images re-uploaded to new paths with alt text discarded.
