Website migration: which agency should you choose to avoid any loss of SEO traffic?
Migrating your website is sometimes necessary (a design overhaul, a change of CMS, technical upgrades, etc.), but it requires careful preparation in advance to avoid any unpleasant surprises regarding your SEO traffic. And many businesses learn this the hard way! A drop in the number of qualified visitors, a slump in click-through rates, fewer leads… and, as a result, a freefall in turnover if you run an e-commerce business. Admittedly, the temptation to have a faster, more modern website is strong, but you need expert support during this transition. With an agency that’s truly competent in SEO, a website migration can be carried out without major disruption, whilst maintaining your search engine rankings. Here’s why.
SEO and website migration: why is this a problem?
When you change a website’s structure, you’re directly altering what search engines already know. For example, Google has indexed your pages, understood how they’re organised, identified which ones are performing well… and a migration disrupts this established order.
Whilst this may seem like a logical step for you, to search engines it’s akin to a new website that has yet to prove itself. And it is this ‘re-learning’ phase that can lead to a loss of visibility, unless you’re supported by a reputable and qualified SEO agency #adsup.
Beware of modified URLs
When migrating from one website to another, URLs generally change (particularly for the purposes of SEO optimisation). And whilst this may seem trivial on paper, in practice Google will treat the old page as having disappeared and the new one as having no history. As a result, the page loses its ranking, even if the content of the page hasn’t changed one iota.
Incorrectly configured redirects
301 redirects are the lifeblood of SEO during a website migration. Let’s take the example of an e-commerce site selling shoes that is removing several categories. Before the migration, a product page such as mysite.com/running-shoes-mike-air was well-ranked on Google and generated regular sales. After the redesign, the page was renamed to mysite.com/running/mike-air, but the redirect was not set up.
Google will then treat the old page as having been completely removed. The result? It is no longer indexed, and all the visibility it had built up is lost…
A shaky internal network
Internal linking is a valuable SEO tool that helps Google understand and crawl a website #hierarchy. Let’s take the example of our shoes website again. Before the migration, the product page for ‘Adsup Performance men’s running shoes’ was accessible via the main categories ‘men’s shoes’ and ‘best sellers’. After the migration, the product page “Adsup Performance men’s running shoes” still exists, but it can now be accessed by clicking on “catalogue” then “sport”, and it no longer appears in the “best sellers” section.
This will have disastrous consequences for your SEO: Google will find it harder to crawl these pages and will gradually reduce their ranking.
Incomplete SEO tags
Here is an SOS from an SEO beacon in distress. That famous coded language whose shorthand is known only to web developers. Think of them as the yellow buoys in a channel that help the Google ship stay on the right course to reach its destination safely.
To put it without resorting to dubious metaphors, they tell Google about the page’s structure and content. During a migration, these tags may be altered, truncated or modified, and the signal becomes less clear to Google, which, as a result, will consider the page to be less relevant for its keywords.
Backlinks that are losing their value
Backlinks in SEO are a bit like a letter of recommendation written by your former boss ✒️. They lend authority and prestige, especially if that boss is a renowned figure in their field. More specifically, when an external website links to one of your pages, it sends a signal to Google: “this content is worth seeing”.
If your page’s URL changes and no redirect is set up, the external link will still exist… but it will no longer lead anywhere. The user will be taken to an error page, and, more importantly, Google will no longer be able to pass on the ‘SEO value’ of that backlink to your new page.
It’s a bit as if the letter of recommendation still existed, but it was addressed to a company that no longer exists.
