SEO migration

SEO migration is a critical and delicate phase in the management of a website, where every step must be carefully planned and implemented to ensure that organic traffic and online visibility do not drop significantly. During an SEO migration, several situations may arise, such as a change of domain, restructuring of site architecture, or a switch to a new CMS.

Each of these operations entails potential risks for search engine positioning, above all:

• drop in traffic and loss of positioning
• drop in conversion rate;
• worsened user experience.

SEO migration is crucial to ensure a smooth transition and to protect investments made in SEO. Correctly implementing an SEO migration minimises the risks associated with the changes, preserving the value gained over time and improving the site’s performance in search engines wherever possible.

Do you have e-commerce? Managing SEO migration is even more important.

Managing an SEO migration for an e-commerce is crucial for preserving organic traffic and maximising growth opportunities. An e-commerce, being closely linked to online sales, cannot afford to lose visibility on search engines, as this directly impacts turnover.

Any change, be it a new platform, architecture restructuring or rebranding, requires special attention to elements such as 301 redirects, URL structure integrity, and content optimisation.

Furthermore, collaboration between the SEO and development teams is crucial to ensure a smooth transition, prevent traffic drops, and improve the user experience. Careful management allows not only to avoid losses, but also to use the migration as an opportunity to improve organic positioning, optimise technical performance and increase conversions.

The migration of a website is a critical moment, as also pointed out by John Mueller, one of Google’s key contact persons.

This moment is delicate because Google organises its index on an individual basis: each URL represents a single unit with associated data. When changing the URL of a page, it is essential to transfer this data via a 301 Redirect, otherwise the value acquired by the page over time will be lost.

However, redirects are not the only activity required to properly manage an SEO migration. Other crucial aspects such as site structure, content and design must also be considered, all of which can significantly affect SEO performance.

As SEO experts in SAY, we are well aware of the potential risks of migration, which is why we scrupulously follow a method that has allowed us to successfully manage many migrations.

Platform migration is among the most complex operations in SEO and requires careful planning and management. The activities can be divided into three main phases.

In this initial phase, the focus is on analysing the current site. A performance analysis is carried out, evaluating key metrics and identifying any critical issues. This phase is crucial to lay a solid foundation for the new site and to define the goals of the migration.

The SEO Audit is an in-depth analysis of the site to be migrated, aimed at identifying both strengths and existing issues. While issues are often already known, strengths require a more detailed analysis to be identified.

It is crucial to recognise and preserve those essential features that contribute positively to website performance. During the SEO Audit, all technical aspects that influence SEO, such as structured data and internal links, must be considered.

In addition, site usability and speed are crucial aspects that need careful evaluation to ensure an optimal user experience and maintain visibility on search engines.

Content analysis aims to identify the site resources that generate the most traffic and conversions. This analysis is also crucial for identifying “underperforming pages”, i.e., pages that do not bring real value to the website and can be eliminated if necessary.

It is important to consider not only pages, but also other content such as images and PDFs, which can generate significant traffic. During this phase, it is recommended to use several tools for analysis, combining the data provided by each of them to obtain a complete and accurate view of the situation.

This approach makes it possible to optimise content, focusing on that which really contributes to the site’s objectives, thus improving overall performance.

The purpose of information architecture is to establish a clear structure for the new website. In this phase, it is crucial to define the content hierarchy, starting from the most general to the most specific, and to define the links between pages.

The architecture must be guided by a well-defined SEO strategy, based on preliminary analyses such as market studies, competitor analysis, industry research and previous content analysis. It is essential to organise the new site on a solid foundation, ensuring that the structure supports the site’s goals and enhances the user experience.

This strategic approach makes it possible to create a site that is easily navigable, optimised for search engines and capable of responding effectively to user needs.

During this phase, the optimisation of the staging site, i.e. the developing version of the new site, is carried out. The functionality of the new site is tested, the effectiveness of redirects, link integrity and the correct setting of metatags are checked. This step ensures that all elements of the site are configured correctly and ready for launch.

In the SEO development and optimisation phase, it is crucial to fulfil the requirements defined in the SEO audit. Each element identified in the audit must be considered and implemented correctly during the development of the new site. Particular attention must be paid to content and meta tags: strategic content must be reported correctly, ensuring an exact match between the old and new site in meta tags such as the title tag and meta description.

This phase also includes redirect management, which is essential to maintain traffic integrity and SEO optimisation. Each page of the old site must be redirected to the corresponding new page, avoiding common mistakes such as massive redirects to the homepage or irrelevant pages. It is crucial not to be in a hurry to go online.

The site being developed and staged must be perfect in all aspects defined in the prerequisites. Only when all requirements are met can the site be considered ready for launch. Careful preparation in this phase ensures a smooth transition and maintenance of visibility on search engines.

This phase is immediately following the launch of the new website. It is essential to carefully monitor what has been implemented, carrying out checks and verifications to ensure that everything is working as planned. This phase includes checking performance and identifying any problems to be promptly resolved.

In the post go-live check and monitoring, it is crucial to consider a few key aspects. First of all, it must be ensured that the site is properly scannable: there must be no blocks, such as those inserted during the development phase in robots.txt files and meta tags.

SEO tags, such as canonical, hreflang, and metatags, must be correct and functional to ensure proper indexing. It is also necessary to check that redirects function correctly, ensuring that they redirect exactly as intended. Monitoring 404 error codes is essential, as there may be pages that, if deleted or not carried over to the new site, return this code. The 404 code indicates that the server cannot find a resource on the website, so it is important to ensure that strategic pages are correctly redirected and that there are no errors. Another crucial aspect is rendering control, that is how the page is displayed by search engine bots.

It is important to check whether there are any blocks or rendered elements in JavaScript, as these can affect crawlability and indexing. Although these checks may seem obvious, they are often the most common errors that cause website problems and drops in performance. At this stage, timeliness is crucial: the faster problems are resolved, the less negative repercussions on the site. By monitoring carefully and acting quickly, you can maintain the visibility and performance of your site at the desired levels.

SEO migration is important because a significant change to the website can drastically affect search engine rankings and organic traffic. A well-planned and properly executed migration can improve site visibility, resolve technical issues, and provide a better user experience. Conversely, a mismanaged migration can cause a loss of traffic, penalisation by search engines, and a decrease in conversions.

Risks associated with SEO migration include:

• Loss of traffic: migration can cause a temporary or permanent decrease in organic traffic if not handled correctly.
• Decline in ranking: changes to URLs, site structure or content can negatively affect search engine rankings.
• Redirect errors: poorly configured redirects can lead to pages not found (404), causing a bad user experience and SEO penalties.
• Indexing problems: if search engines fail to index the new site correctly, pages may not appear in search results.
• Loss of backlinks: links from other sites may no longer work properly, reducing the domain authority.

Carefully managing the migration process and monitoring results is crucial to mitigate these risks.

The time required to complete an SEO migration can vary widely depending on the complexity of the site and the type of migration. However, in general, the process can be broken down into three main phases:

• Planning and preparation (2-6 weeks):

1. Analysis of the current site and identification of critical areas.
2. Creation of a detailed migration plan.
3. Configuration of the staging environment and preliminary testing.

• Execution of the migration (1-2 weeks):

1. Implementation of the migration according to the plan.
2. Configuring redirects and updating sitemaps.
3. Verification and resolution of problems detected during migration.

• Post-migration monitoring (4-8 weeks):

1. Monitoring of traffic, rankings and redirect errors.
2. Correction of any problems that emerge.

• Ongoing review and optimisation to ensure SEO performance is maintained.

In total, the complete SEO migration process can take about 2 to 4 months, depending on the specific needs of the project and the available resources, but the timing depends mainly on the developers.

If problems occur after SEO migration, it is crucial to act promptly to minimise the negative impact. Use tools such as Google Analytics and Google Search Console to quickly identify traffic drops, indexing errors and redirect problems.

It is important to check that all 301 redirects are configured correctly and that the robots.txt file is not blocking search engine access. Ensure that the new XML sitemap is updated and sent to the search engines and that all internal links point to the new URLs without broken links. Identify and correct 404 errors, redirecting them to the correct pages.

If problems persist, relying on an SEO expert is important for a thorough review.

During an SEO migration, it is important to avoid some common mistakes to minimise risks and ensure a smooth transition. One of the most common mistakes is not planning the migration process properly, underestimating the complexity and importance of detailed preparation.

Neglecting to create and test 301 redirects can lead to significant losses in traffic and visibility on search engines. Another common mistake is not properly updating the robots.txt file and sitemaps, preventing search engines from properly indexing the new site. It is also crucial to avoid ignoring the preliminary SEO performance analysis of the old site, which may result in the loss of content and pages with high SEO value.

Furthermore, not actively monitoring the site after migration may delay the detection and correction of critical problems. Finally, lack of communication with key stakeholders can cause misalignments. Avoiding these mistakes can significantly increase the likelihood of a successful SEO migration.
