FAQs

  • Why do I need an SEO migration agency for my WordPress migration if I have a web development partner?

    WordPress developers are skilled at building and configuring WordPress sites, but they do not own or manage SEO performance. WordPress migrations carry a specific set of SEO risks, permalink structure changes, plugin conflicts, metadata loss, and taxonomy restructuring, that a developer will not typically identify or mitigate. Partnering with an SEO agency during your WordPress migration gives you a dedicated expert who understands how the platform interacts with search engine crawling and indexing, ensuring no performance is lost through the transition that could have been protected.

  • Can a WordPress migration plugin handle my migration?

    Migration plugins such as Duplicator, All-in-One WP Migration or WP Migrate can assist with moving WordPress files and databases between environments, but they cannot manage the SEO implications of a migration. They do not audit your existing performance, identify at-risk pages, implement or validate redirects, or ensure search engine compliance on the new build. A plugin moves your site; an SEO migration agency protects its performance. The two serve entirely different functions.

  • What is a WordPress website migration?

    A WordPress website migration refers to any significant change made to a WordPress site that alters how it is crawled, indexed or experienced by users and search engines. This could include moving to a new hosting environment, switching domain names, migrating from another CMS to WordPress, redesigning the site with a new theme or page builder, or restructuring URLs and site architecture. Each type of migration introduces its own SEO risks, which must be actively managed to avoid traffic and ranking loss.

  • Can WordPress developers handle a WordPress SEO migration?

    WordPress developers are well-placed to manage the technical execution of a migration, but SEO is a distinct discipline that sits outside the scope of development work. Developers routinely overlook permalink changes that break redirect chains, theme switches that strip structured data, or plugin migrations that affect crawl behaviour. An SEO migration agency works alongside your development team to ensure every decision made during the build is evaluated through the lens of search performance.

  • How does changing WordPress theme or page builder affect my SEO during a migration?

    Changing WordPress theme or page builder, for example, moving from Elementor to a block-based theme, or switching from a custom theme to a commercial framework, is one of the most commonly underestimated sources of SEO risk in a WordPress migration. Theme changes can alter heading hierarchy, strip structured data, remove schema markup, change internal linking patterns and affect Core Web Vitals scores, all of which have a direct impact on search performance. As part of our technical evaluation, we audit the SEO implications of your theme change specifically, ensuring the new build matches or improves on the structural and performance signals of the existing site before a single page goes live.

  • What are the biggest SEO risks when migrating from another CMS to WordPress?

    Migrating to WordPress from another platform introduces a specific set of risks beyond those of a like-for-like WordPress migration. URL structures frequently change entirely when moving between platforms, meaning every indexed page needs a redirect to its WordPress equivalent. Content formatting, metadata and structured data often fail to transfer cleanly in automated migrations, requiring manual auditing and correction. Taxonomy structures, navigation logic and internal linking patterns must be rebuilt in the WordPress environment in a way that preserves the information architecture of the original site. We manage each of these workstreams in parallel, ensuring no dimension of your SEO performance is overlooked during the platform switch.

  • 4. Technical Evaluation & Transition Strategy
  • 5. Post-Launch Performance Monitoring & Insights

Before initiating any WordPress transition, we conduct a meticulous examination of your site's search visibility, organic performance and technical framework.

By establishing detailed benchmarks across your WordPress rankings, traffic, key landing pages, permalink structure and on-page signals, we identify the content and technical elements that underpin your current search presence. This ensures that every critical asset — from category pages to individual posts — is preserved and optimised throughout the transition, safeguarding your site's authority, usability and search prominence.

This positions POLARIS as your WordPress SEO stakeholder from the outset, ensuring every development and design decision made about the new build is evaluated through the lens of organic performance before a single change is made live.

We undertake a thorough examination of your most valuable WordPress content, from posts and pages to tags, assessing its structure, internal linking, metadata and continued relevance within the evolving digital landscape.

By scrutinising the proposed architecture and content structure of your new WordPress build alongside a competitor analysis, we ensure continuity and enhancement of your existing strengths. This comparative review provides a strategic perspective on what must be preserved and where the new site has the opportunity to outperform the current one.

We develop and deploy a bespoke tracking framework on your new WordPress environment, aligned with your business objectives and configured to capture precise insights into user interactions and site performance from day one post-launch.

Our data-driven approach ensures you never lose visibility of how users are engaging with your site during or after the migration. Additionally, we ensure full compliance with search engine guidelines, including XML sitemap configuration, robots.txt validation and Google Search Console setup on the new WordPress build. This safeguards long-term organic visibility and indexing accuracy.

By emulating the behaviour of search crawlers, we conduct an in-depth assessment of how your new WordPress build will be indexed and navigated.

Covering permalink structure, plugin configuration, theme implementation, Core Web Vitals performance and site architecture, we identify and resolve any crawlability or indexation issues before the site goes live, and create a comprehensive redirect strategy that maps every URL change to its correct destination. This proactive approach ensures a clean, disruption-free changeover with minimal impact on rankings, user experience or business performance.

Following the successful launch of your new WordPress site, we conduct meticulous manual evaluations of your search visibility and site performance, ensuring search engines are correctly crawling and indexing your new structure and that all redirects are functioning as intended.

We rigorously test user journeys, tracking implementation and on-page signals to verify that the new WordPress environment is performing at the level established during our pre-migration benchmarking. We provide ongoing performance assessments for up to four weeks post-launch, delivering actionable insights to safeguard rankings, traffic and overall digital effectiveness as your new site settles into its search presence.
