Http error: 416 – Requested Range Not Satisfiable

416 - Requested Range Not Satisfiable

in this article

The 416 status code, or Requested Range Not Satisfiable error, indicates that the server cannot satisfy the request because the requested range is not valid. This error is most often caused by an invalid or missing Range header. 

The 416 status code is relevant in SEO because it can cause pages to be erroneously excluded from search engine indexing. This often happens when a search engine bot requests a page from a server, but the server responds with a 416 error because the requested range is invalid. As a result, the search engine may think that the page does not exist and will not index it. 

The best way to prevent this from happening is to make sure that your server is configured to return a 404 status code instead of a 416 status code for pages that do not exist. You can do this by setting the “server.error-pages” property in your server’s configuration file. 

For more information about the 416 status code, please see RFC 7231, section 6.5.14.

"In a digital world, a company’s sales footprint is only as large as its digital market exposure." Backstory My perspective on growth was forged at 18 in an Armoured Reconnaissance unit of the Canadian Armed Forces. While that time taught me about preparation and mission-focus, the deepest lesson was about people. I learned early on that the difference between success and total failure is the integrity of the person standing next to you. Since then, through over a decade navigating the complexities of startups, consultancies, and financial institutions, I’ve developed a visceral "allergy" to the masqueraders—those who look the part but aren't "in it." In the high-stakes world of B2B SaaS, there is no room for the non-craftsperson. I built Productive Shop on the opposite principle: The Craft. I am a dedicated advocate for the "marketing craftsman," believing that technical excellence and a drive to win are the only sustainable competitive advantages in a digital-first economy. I’ve spent my career building "mission-ready" marketing teams that understand a fundamental truth: a company’s digital footprint is its reality. My academic background in Criminology, Justice, and Political Science from Toronto Metropolitan University (formerly Ryerson) gave me a unique lens into systemic risk and policy—a vantage point I now use to help companies in "old school" industries like Fintech, Cybersecurity, and GovTech modernize their presence and capture dominant market share. On the lookout for I act as a strategic advisor to companies ranging from Seed to Series B, helping them transition from early-stage obscurity to dominant market leaders. I work closely with institutional investors to ensure their portco valuations aren't just protected, but actively inflected by their go-to-market foundations. I’m a firm believer that a dominant search presence and smart advertising targeting are the bedrock of modern pipelines. I look for founders who are pushing the boundaries of what is possible in traditionally rigid industries. If you are a founder ready to stop "playing" at marketing and start building a world-class foundation that owns the market narrative, I want to be the person who helps you get there. When I'm not scaling SaaS pipelines or sharpening a brand's digital edge, you can find me on the slopes as an avid skier or at the range as a marksman—pursuits that, much like my work, require precision, discipline, and a high-performance mindset.
