Website Migration Support
A site migration that doesn’t tank your rankings.
Most site migrations lose significant organic traffic – not because the build was bad, but because SEO wasn’t in the room until after launch. BridgeCity manages every stage so your rankings survive the transition.
Site migrations are one of the highest-risk SEO events your business will face.
A well-executed migration leaves your organic traffic intact. A poorly executed one can take 6 to 12 months to recover from – if it recovers at all. The failure modes are well understood and entirely avoidable with proper SEO oversight.
Broken redirects
Old URLs that do not redirect properly send search engines and users to dead ends. Rankings built over years can disappear in days when redirect maps are incomplete or implemented incorrectly.
Lost crawl signals
New site structures that do not preserve internal linking and crawl priority cause pages that ranked before to drop off search entirely. Crawl budget mismanagement is especially damaging on larger sites.
Dropped indexation
Noindex tags left on from staging, sitemaps not submitted, or canonical conflicts can prevent entire sections of a new site from appearing in search, sometimes for weeks before anyone notices.
Domain authority loss
Platform changes, domain switches, or restructures that do not properly consolidate authority signals can reset years of link equity. Backlink-to-new-URL mapping is non-negotiable.
Content mapping gaps
Pages with established rankings and backlinks that get deleted, restructured without redirects, or rewritten with diluted keyword signals lose traffic fast – often before anyone connects the content change to the traffic drop.
AI visibility disruption
Structural and schema changes can reduce how accurately AI platforms like Google AI Overviews and ChatGPT represent your brand. Entity-level visibility requires its own migration checklist.
SEO oversight at every stage – not just cleanup after.
“Most SEO problems from site migrations happen because SEO was not involved until after launch. BridgeCity works with your team from the planning phase through stabilization.”
The window to prevent migration SEO damage is before and during the build – not after. Waiting until traffic drops to bring in an SEO consultant means spending weeks or months diagnosing and reversing what should never have happened. BridgeCity works as part of your migration team, not as a post-launch recovery service.
Pre-migration audit
Full inventory of your current rankings, top pages, backlink profile, internal link structure, and any existing technical issues. Nothing gets built without a clear baseline of what needs to be preserved.
URL mapping and redirect planning
Every URL that matters gets mapped to its new destination. Redirect chains are flagged and eliminated. Pages that should not be redirected are identified and retained. The redirect map is delivered before any dev work begins.
Staging environment review
Before launch day, a full review of the staging build covers crawl accessibility, metadata accuracy, canonical tags, structured data, internal linking, noindex settings, and AI bot accessibility.
Launch day support
Available on launch day to triage issues as they surface: redirect failures, crawl errors, unexpected indexation changes. The highest-risk window in any migration is the first 24 hours.
Post-migration monitoring
30 to 90 day monitoring of rankings, crawl data, indexation, and traffic to identify and resolve anything that slipped through staging review. Post-launch is when the real data arrives.
What you get
A complete SEO migration package: from pre-launch planning through post-launch stabilization.
You need SEO migration support if you are doing any of these.
Replatforming your site
Moving from WordPress to Webflow, Shopify to a custom build, or any platform change that restructures your URLs, templates, or site architecture.
Redesigning your site
A full design or content overhaul that changes page structure, navigation, URL patterns, or the content on pages that currently rank.
Switching domains
Rebrands, consolidations, or domain cleanups that require transferring all organic ranking signals from an existing domain to a new primary one.
Merging multiple sites
Combining two or more websites after an acquisition or consolidation, without losing the ranking equity either site built independently.
Moving to HTTPS
Still on HTTP? A protocol migration handled correctly protects your traffic. Handled poorly, it creates a mess of mixed content issues and redirect loops that suppress rankings for months.
Recovering from a bad migration
Already migrated and lost significant traffic? Post-migration SEO recovery starts with understanding exactly what broke – and building a methodical, prioritized fix plan.
Questions about SEO website migration services.
How far in advance should I involve an SEO before migrating?
Ideally 4 to 8 weeks before launch: enough time to complete a full audit, build the redirect map, and review the staging environment before your team has committed to a build approach that is hard to change. Engaging earlier is always better. Two weeks before launch is the absolute minimum for a meaningful pre-migration review, and at that point some options are already off the table.
Is this a one-time project or does it work as part of a retainer?
Site migration support is available as a standalone project engagement. Clients on an ongoing BridgeCity retainer already have migration support built into the partnership. If you are planning a migration while on retainer, it is covered. If you are not currently on retainer, a project engagement is the right fit. Either way, reach out and we will figure out the right structure.
My developer says they will handle SEO during the migration. Do I still need this?
Developers are excellent at building things correctly. SEO migration requires a different lens entirely – understanding which pages hold ranking signals worth preserving, how to structure redirect logic across hundreds or thousands of URLs without creating chains, how crawl budget affects indexation during a transition, and how to monitor what Google actually does after launch. These are specialist skills that sit outside the dev scope. The two are complementary, not interchangeable.
What if I have already migrated and my traffic dropped?
Post-migration traffic recovery is a specific engagement. The first step is a post-migration audit that identifies exactly what happened: broken redirects, lost indexation, metadata issues, authority fragmentation, or a combination. Once the root causes are documented, BridgeCity builds a prioritized remediation plan and works through it systematically. Recovery timelines depend on how severe the damage was and how quickly fixes can be implemented, but most sites with clear causes can stabilize within 60 to 90 days of beginning a structured recovery.
Does migration SEO cover AI and generative search visibility?
Yes. Structural and schema changes during a migration can meaningfully affect how AI tools like Google AI Overviews, ChatGPT, and Perplexity understand and represent your brand. BridgeCity’s migration process includes AI bot accessibility review, entity representation checks, and schema continuity as standard parts of the staging review and post-migration monitoring, not as a separate track you have to ask for.
After the migration, the organic growth work begins.
