Understanding the Impact of Excessive Redirects in SEO: A Case Study of 12,000 301 Redirects
In the ever-evolving landscape of search engine optimization, effective strategies hinge on best practices, sound logic, and a keen understanding of how search engines interpret website signals. Recently, an anecdote surfaced illustrating the pitfalls of misguided SEO efforts—particularly the unnecessary creation of thousands of redirects—highlighting the importance of strategic decision-making in digital marketing.
Background: Outsourcing Content and SEO Optimization
A company engaged a marketing firm to enhance its website’s aesthetics and content. While the visual updates were well-executed and appreciated, the SEO improvements proposed by the marketing team raised questions. The company’s internal SEO knowledgeable staff maintained that a clean, well-structured site combined with engaging content and standard SEO practices usually sufficed.

What was uncovered was surprising: nearly every URL that had recently resulted in a 404 error—such as paths like /deploy/aws.credentials or /db.yml—had been redirected to some other location.
These URLs appeared to be hits from malicious or automated sources, commonly referred to as “script kiddies,” which often probe websites for vulnerabilities or orphaned links. The redirects, in essence, turned potentially benign 404 responses into hosted redirect destinations, artificially altering traffic reports.
Potential Consequences of Excessive Redirects
While at first glance, redirecting erroneous URLs might seem like a cleanup exercise, this practice can have unintended—and sometimes detrimental—effects:
-
Dilution of Crawl Efficiency: Search engines allocate crawl budgets to websites, prioritizing crawling important and authoritative pages. Redirecting numerous low-value or malicious URLs can waste crawl resources and impede indexing of genuine content.
-
Misleading Analytics: Redirects from meaningless or malicious URLs inflate traffic metrics, skewing data and making it difficult to accurately assess genuine user engagement.
