Key takeaways
- Croton Content's audit of Valery Real Estate found 324,580 pages returning 404 errors after a September 2024 rebrand left old URLs without redirects.
- Weekly organic sessions had fallen to a floor of 974 by May 2025, the point at which the audit was delivered and the fix was scoped.
- 301 redirects went live in late August 2025, about three months after the audit, and weekly sessions reached 5,847 within the first week and peaked at 12,276 by late September.
- Full-year organic sessions rose from 14,918 in 2024 to 220,570 in 2025, a 1,379% year-over-year increase, and registrations more than doubled after the fix.
- Croton Content is explicit this was recovery of authority trapped behind broken URLs, not new growth, and the fix sat unimplemented for three months.
A rebrand that swaps a site’s URL structure is routine. What Valery Real Estate’s case shows is how expensive it is to skip the one step that makes a rebrand safe: mapping every old URL to where it now lives. Croton Content, the agency that audited and later fixed the site, published the client’s real numbers. We read the case study directly.
What the audit found
Valery Real Estate, a Canadian property listings platform, relaunched under its current name in September 2024, replacing its earlier ChatVal URL structure. No redirects were put in place from the old addresses to the new ones. By the time Croton Content audited the site in May 2025, the damage had compounded silently for eight months: 324,580 pages were returning 404 errors, and a further 506,104 pages were being crawled by Google but marked “crawled, currently not indexed.”
The case study attributes most of the non-indexed pages to a separate but related problem: property listings sat behind an authentication gate with too little content visible before login, price, summary, neighborhood, for Google to judge their relevance. Organic sessions had fallen to a weekly floor of 974 by May 2025, down from 14,918 total sessions across the four months following the September 2024 launch.
The fix, and the three-month gap before it shipped
The prescription was not complicated: 301 redirects mapping every broken URL to its working equivalent, a cleaned XML sitemap with the 404 entries removed, and enough listing content exposed above the login gate for Google to evaluate the pages. What is notable is the gap between diagnosis and action. The audit was delivered in May 2025; the redirects did not go live until late August 2025, three months later.
Once they shipped, the response was immediate. Weekly organic sessions reached 5,847 in the first week of September and peaked at 12,276 for the week of September 17 to 23, a 12.6x increase over the May floor. October and November settled to roughly 8,500 sessions a week, still about six times the pre-fix baseline. Full-year organic sessions rose from 14,918 in 2024 to 220,570 in 2025, a 1,379% year-over-year increase. Organic registrations went from about 1,370 across the eight months before the fix to 2,985 in the four months after it.
Why the agency calls this recovery, not growth
Croton Content is explicit that the 301 redirects did not add rankings, content, or domain authority to the site. They unlocked authority the site had already built, in links, in indexed pages, in ranking positions, that the broken URL structure had made unreachable since the rebrand. The case study also names its own weak point: a three-month lag between finding the problem and fixing it, during which the site kept losing the same traffic the audit had already diagnosed.
Why we care
The lesson generalizes past this one site. A URL restructure without a complete redirect map does not lose traffic gradually, it can strand traffic the site already earned behind pages that no longer resolve, and the loss compounds for as long as the redirects are missing. Valery’s numbers show both halves of that: eight months of decay from a launch with no redirect plan, and a recovery inside three weeks once the mapping went live. The gap between those two speeds is the redirect map itself, not new content or new rankings.

Frequently asked questions
What broke on Valery Real Estate's site?
A September 2024 rebrand from ChatVal to Valery restructured the site's URLs without implementing redirects. Croton Content's audit, delivered in May 2025, found 324,580 pages returning 404 errors and a further 506,104 pages that Google had crawled but declined to index.
Why were so many pages crawled but not indexed?
The case study attributes most of that second count to listing pages gated behind an authentication wall. Google could reach the URLs but found too little visible content, price, summary, neighborhood, to evaluate before a login prompt, so it left them out of the index.
How long did the fix take to show results?
The audit was delivered in May 2025, but the 301 redirects mapping old URLs to their working equivalents did not go live until late August 2025, a three-month gap. Weekly organic sessions still reached 5,847 within the first week of the fix and peaked at 12,276 by the week of September 17 to 23.
Is 1,379% a fair way to describe what happened?
Croton Content frames it as recovery rather than growth. The redirects unlocked backlink authority and rankings the site had already earned before the rebrand but could not use while the URLs 404'd; the agency states no new content, rankings, or domain authority were added to produce the increase.
