Should you really redirect an old category to just one of the new URLs?

Why does Google allow a redirect to just one URL among several?

When you restructure a product catalog, splitting a broad category into several subcategories is a common practice. The old /sport-shoes becomes /running-shoes, /trail-shoes, /fitness-shoes.

The classic issue: you have a historical URL that has accumulated backlinks, authority, and crawl history. Losing it to a 404 or outright deletion would be wasteful. Google clearly states that a 301 redirect to one of the new categories is acceptable, even if it does not cover 100% of the initial scope.

Which page should be chosen as the redirection destination?

The logic dictates that you redirect to the category most representative of the old URL or the one that generates the most volume. If /sport-shoes historically sent 70% of traffic to running, /running-shoes becomes the natural target.

The other categories (trail, fitness) do not lose out: they must be normally linked within the site, with strong internal linking from the homepage, the menu, the product pages, and the new destination category. The key is that Google should be able to discover and crawl them without friction.

Could the other URLs resulting from the split be penalized?

No, as long as you respect the logical structure of the site. Google does not penalize the fact that an old URL redirects to a single new page while others exist in parallel. What matters is that each page has its SEO reason to exist: unique content, a distinct search intent, a product volume justifying the category.

The risk would be creating empty or nearly identical categories, or failing to link them correctly. In that case, Google could ignore them or consider them as low-quality content, regardless of the redirection.

• A 301 redirect to one of the new categories preserves the authority of the old URL without unnecessary dilution
• The other categories resulting from the split must be actively linked within the site to ensure their crawl and indexing
• Choosing the destination page based on historical traffic or semantic representativeness maximizes SEO continuity
• Avoid creating hollow categories that add no value in terms of intent or volume
• Monitor the indexing of the new URLs via Search Console to validate that Google is discovering them properly

Is this recommendation consistent with observed field practices?

Yes, and it is even a welcome confirmation of a common practice. E-commerce SEOs regularly handle catalog restructurings, and the question 'which page to redirect to?' keeps coming up. Google validates here that it is not necessary to create an artificial interstitial page listing all the new categories just to 'cover' the old URL.

However, this statement remains surprisingly brief on a critical point: what happens if the old category covered very different intents, with balanced volumes between the new URLs? [To verify]: in this case, a single redirect could frustrate part of the direct traffic or backlinks pointing to the old URL.

What nuances should be added based on context?

The guideline works well when one of the new categories is clearly dominant in volume, historical traffic, or backlinks. If /sport-shoes received 80% of its traffic from 'running' queries, redirecting to /running-shoes makes sense.

But if the split creates three equivalent categories, you end up with an arbitrary choice that may disappoint users and dilute the experience. In that case, a more robust alternative would be to create a hub page /sport-shoes that lists the three new categories with editorial blocks and strong internal links. This page would then become the destination of the 301, preserving authority while properly directing traffic.

In what cases could this rule pose a problem?

Let's be honest: Google says nothing about managing backlinks pointing to the old URL. If you redirect /sport-shoes to /running-shoes, the historical backlinks will boost this single category. The others (trail, fitness) start from scratch in terms of external popularity, unless you manage to negotiate link updates with referring sites.

Another point: the statement assumes that 'the new pages must be linked normally.' But what does 'normally' mean? A link in the footer? A link in a mega-menu? A link from every product sheet? The granularity is not specified, and in practice, weak linking may be enough for Google to ignore the new categories, especially if they are deep in the structure.

What should you do concretely when splitting a category?

Start by analyzing the historical traffic and backlinks of the old URL. If one intent dominates (for example, 70% of sessions come from 'running' queries), redirect to the category most aligned with this intent. This way, you preserve user and SEO continuity.

Next, ensure that the other categories resulting from the split are linked from at least 3 strategic points: main menu, homepage, and destination page of the redirect. A contextual link in a 'See also' block on /running-shoes pointing to /trail-shoes and /fitness-shoes is a minimum. The easier you make discovery, the faster Google will crawl these new URLs.

What mistakes should be avoided when implementing redirects?

Never redirect to a page that does not yet exist or that is temporarily noindex. It seems obvious, but e-commerce migrations are often rushed, and redirects point to non-indexable pages. Result: you lose the authority of the old URL without recovering anything.

Avoid creating redirect chains. If /sport-shoes redirects to /running-shoes, and /running-shoes redirects elsewhere, Google may lose part of the signal. A direct, clean 301 permanent redirect is the only valid option. Finally, do not neglect monitoring in Search Console: check that the new URLs are indexed and that they are receiving traffic in the weeks following the migration.

How to verify that Google is properly considering the restructuring?

Use URL inspection in Search Console for each new category. Look at the last crawl date, the declared canonical URL, and indexing. If a category does not appear in the index after 2-3 weeks, it’s a warning signal: either it is poorly linked or too close to another page, and Google considers it duplicate.

Also monitor the evolution of organic traffic on each new URL through GA4 or your analytics tool. If the total traffic of the new categories is lower than the traffic of the old URL, you probably lost visibility. In that case, strengthen the internal linking and consider creating unique editorial content for each category to differentiate intentions.

• Analyze the traffic and backlinks of the old URL to choose the most coherent destination page
• Implement a direct 301 redirect to the dominant category, without redirect chains
• Actively link the other categories from the menu, the homepage, and the redirect destination page
• Check the indexing of each new URL via Search Console within 2-3 weeks following the launch
• Monitor the organic traffic of each category to detect any loss of visibility
• Create unique editorial content for each new category to differentiate intentions and avoid duplicate content
