URL Structure Repair & Redirect Management

404 errors after a WordPress migration mean your SEO is bleeding. We stop it.

Every broken link to your site is a lost visitor and a wasted backlink. Every 404 your Google crawl report shows is a ranking opportunity disappearing. After a migration, redesign, or domain change, broken URLs must be systematically identified and redirected, not left to accumulate.

Case Study: The Agency Whose Blog Traffic Dropped 60% After a Redesign

SymptomA digital marketing agency launched a new website redesign. The new site used a different URL structure for blog posts (from `/news/post-name/` to `/blog/post-name/`). Three months after launch, their organic traffic was down 60% from pre-launch levels.

Resolution140 blog posts, many with established rankings and backlinks, were returning 404 errors at their original URLs. No redirects had been implemented. Google Search Console showed these 140 URLs generating 2,400 "Not found" crawl errors per month.

Business Impact

We mapped all 140 old URLs to their new equivalents, implemented 301 redirects, and submitted the corrected sitemap to Google. Organic traffic began recovering within three weeks and had returned to 85% of pre-launch levels within 60 days. The remaining 15% gap was attributable to ranking positions that had been redistributed to competitors during the three-month unredirected period.

Common questions

Questions answered.

How many 404 errors constitute a significant SEO problem?

Any 404 on a previously-ranked or externally-linked URL is a problem. Even a single 404 on a page with strong backlinks represents meaningful lost ranking authority. Scale matters for the urgency of the fix, not for whether the fix is needed.

My site was just migrated a week ago. Is it too late?

It's not too late, but sooner is always better. Every week without redirects allows Google to recalibrate its index without your URLs, making recovery progressively more difficult.

Do I need redirects for pages that got very little traffic?

For pages with external backlinks, yes, regardless of traffic volume. Backlinks carry domain authority that is lost when the linked URL 404s. For internal pages with no external links and no historical rankings, the priority is lower.

Will 301 redirects fully transfer my page rankings to the new URL?

Research consistently shows 301 redirects transfer the vast majority (90–99%) of ranking authority to the destination URL. Implementing them promptly after a migration prevents the authority decay caused by unresolved 404 errors.
