Often we are drafted into a web project before it has begun, so that we can manage the development of a new solution from initiation. Working from the ground up, we start by partnering with you and your development stakeholders to identify a series of project plans together.

This ensures that POLARIS can act as your SEO stakeholder from the beginning and critique every decision made with regards to the new site that will soon be launched.

We know the value of your website to your business and we document what this looks like so that we can all understand what needs to be protected as we head into the project together.

Traffic sources, statistics, conversions and values are some of the metrics documented.

Analysing your existing user journey against the proposed user journey is a critical step in ensuring performance is retained.

We will audit the performance of your existing site by evaluating both the site architecture and top performing page layouts.

By analysing both of these areas, we will be able to determine which areas of your existing experience are critical to success and how these must evolve to be maintained within the new site you aim to launch.

Website Migration FAQs

  • What is website migration?

    A website migration refers to the process of moving a website from one web hosting environment or platform to another. This could involve changing hosting providers, switching domain names, or even redesigning and restructuring the website. Website migrations are often done to improve performance, security, or functionality.

  • How long does a website migration take?

    Before initiating a migration, it's essential to be aware of the following requirements and service limitations. While the majority of migrations are typically completed within 2-3 weeks, larger projects may require more time, our expert migration team will be on hand to advise with this. Your current website must remain operational throughout the migration, and any changes made to the site after migration approval will not be reflected in the migrated content. If you have any questions or require further assistance, please don't hesitate to contact a member of our team.

  • How do I prepare for a website migration?

    Before your website migration, our team conducts a comprehensive Website SEO migration audit. This audit involves a thorough evaluation of your existing website's performance, including factors such as rankings, technical aspects like speed and page load times. By benchmarking these statistics, we can provide a basis for comparison and report on the impact of the migration once it's completed.
