Keynote unveiled its completely revamped Web Performance Indices providing global website owners the latest user-centric criteria for benchmarking performance.
Keynote's enhanced Web Performance Indices now include three new measurements, representing the cutting edge in determining how well a consumer experiences content and interacts with a website.
With the addition of these metrics, site operators can now view performance beyond just Web server or network responsiveness, and understand details like when a user first sees something other than a blank page, or when a page can be fully clicked, swiped or scrolled.
Bill Gassman of Gartner says, "Benchmark your website's speed across different types of devices and networks, for the most important and most common user tasks (mobile and desktop users) before you make any changes so that you can gauge the effect of investments in enhancement tools and techniques"
The enhanced indices raise the bar for companies striving to deliver a better online experience to customers with new precision, unavailable anywhere else.
The significance of adding user experience metrics is that site operators can now view performance beyond the perspective of only Web server or network responsiveness. These metrics represent important events in a page's lifecycle and makes the difference between a user seeing something – and nothing.
For example, a user visits two sites, each with a Total User Experience Time of five seconds. If site A starts displaying content in half a second but site B does not start rendering any content until four seconds, the perception of site A will be more positive, even though both sites have the same overall five second user experience time.
Keynote publishes 43 separate indices each comprised of hundreds of sites tracking all major business verticals, plus localized versions around the world. These include sites in the US, Europe, Australia and Japan, plus government sectors and industries such as banking, brokerage, credit card, lodging, apparel, books-music-video, electronics, automotive, startups, social networking and news. Data is available on a weekly basis, free of charge, with email alerts.
The company is also introducing the PerfDex API, a new free service that developers can use to access a real-time data stream of the Keynote Business 40 Index data.
The Latest
Like most digital transformation shifts, organizations often prioritize productivity and leave security and observability to keep pace. This usually translates to both the mass implementation of new technology and fragmented monitoring and observability (M&O) tooling. In the era of AI and varied cloud architecture, a disparate observability function can be dangerous. IT teams will lack a complete picture of their IT environment, making it harder to diagnose issues while slowing down mean time to resolve (MTTR). In fact, according to recent data from the SolarWinds State of Monitoring & Observability Report, 77% of IT personnel said the lack of visibility across their on-prem and cloud architecture was an issue ...
In MEAN TIME TO INSIGHT Episode 23, Shamus McGillicuddy, VP of Research, Network Infrastructure and Operations, at EMA discusses the NetOps labor shortage ...
Technology management is evolving, and in turn, so is the scope of FinOps. The FinOps Foundation recently updated their mission statement from "advancing the people who manage the value of cloud" to "advancing the people who manage the value of technology." This seemingly small change solidifies a larger evolution: FinOps practitioners have organically expanded to be focused on more than just cloud cost optimization. Today, FinOps teams are largely — and quickly — expanding their job descriptions, evolving into a critical function for managing the full value of technology ...
Enterprises are under pressure to scale AI quickly. Yet despite considerable investment, adoption continues to stall. One of the most overlooked reasons is vendor sprawl ... In reality, no organization deliberately sets out to create sprawling vendor ecosystems. More often, complexity accumulates over time through well-intentioned initiatives, such as enterprise-wide digital transformation efforts, point solutions, or decentralized sourcing strategies ...
Nearly every conversation about AI eventually circles back to compute. GPUs dominate the headlines while cloud platforms compete for workloads and model benchmarks drive investment decisions. But underneath that noise, a quieter infrastructure challenge is taking shape. The real bottleneck in enterprise AI is not processing power, it is the ability to store, manage and retrieve the relentless volumes of data that AI systems generate, consume and multiply ...
The 2026 Observability Survey from Grafana Labs paints a vivid picture of an industry maturing fast, where AI is welcomed with careful conditions, SaaS economics are reshaping spending decisions, complexity remains a defining challenge, and open standards continue to underpin it all ...
The observability industry has an evolving relationship with AI. We're not skeptics, but it's clear that trust in AI must be earned ... In Grafana Labs' annual Observability Survey, 92% said they see real value in AI surfacing anomalies before they cause downtime. Another 91% endorsed AI for forecasting and root cause analysis. So while the demand is there, customers need it to be trustworthy, as the survey also found that the practitioners most enthusiastic about AI are also the most insistent on explainability ...
In the modern enterprise, the conversation around AI has moved past skepticism toward a stage of active adoption. According to our 2026 State of IT Trends Report: The Human Side of Autonomous AI, nearly 90% of IT professionals view AI as a net positive, and this optimism is well-founded. We are seeing agentic AI move beyond simple automation to actively streamlining complex data insights and eliminating the manual toil that has long hindered innovation. However, as we integrate these autonomous agents into our ecosystems, the fundamental DNA of the IT role is evolving ...
AI workloads require an enormous amount of computing power ... What's also becoming abundantly clear is just how quickly AI's computing needs are leading to enterprise systems failure. According to Cockroach Labs' State of AI Infrastructure 2026 report, enterprise systems are much closer to failure than their organizations realize. The report ... suggests AI scale could cause widespread failures in as little as one year — making it a clear risk for business performance and reliability.
The quietest week your engineering team has ever had might also be its best. No alarms going off. No escalations. No frantic Teams or Slack threads at 2 a.m. Everything humming along exactly as it should. And somewhere in a leadership meeting, someone looks at the metrics dashboard, sees a flat line of incidents and says: "Seems like things are pretty calm over there. Do we really need all those people?" ... I've spent many years in engineering, and this pattern keeps repeating ...
