Best Practices for Creating a Culture of Web Performance

What do the most successful websites have in common? They all have a strong culture of web performance and usability. Here are some proven tips and best practices to help you create a healthy, happy, celebratory performance culture.

Creating a strong performance culture means creating a feedback loop in your company or team that looks like this:

In other words: Get people to care, show them what they can do to help, and then give them positive reinforcement when you get results. 

It's basic human psychology, and it might seem obvious when you see it in a graphic. But it's surprisingly easy to miss these steps, skip ahead to the part where you invest in performance tools, and then wonder why all your performance efforts feel like such a painful uphill slog.

Identify what people care about

If you ask different people in your organization how much they care about performance today, you might get a bunch of blank stares. But if you gave them a checklist and asked them to tick off any of the following boxes of things they care about, you'd probably get a more enthusiastic response:

  • bounce rate
  • cart size
  • conversions
  • revenue
  • time on site
  • page views
  • search traffic
  • user satisfaction
  • user retention

Performance can be mapped to all of these metrics – and almost any other business metric you can think of. To hook different people on performance, you need to understand which metric motivates them.

For example, an executive might want to know the impact of performance improvements and slowdowns on conversions and overall revenue, while folks in your marketing team might focus on the impact of performance on everything from SEO to user engagement.

Once you know what people care about, connect the dots for them. Case studies (such as those curated at are an excellent way to do this. For example, if someone on your executive team cares about conversions and revenue, you can direct them to a set of studies that focus on the impact of performance on revenue and conversion rate. People on your marketing team probably care about traffic and engagement. And so on.

Case studies are a great way to convert performance skeptics. They're also a great way to get people fired up about making your site faster. When you learn, for example, that Staples reduced its median load time by 1 second and saw a 10% increase in conversion rate, that's pretty compelling. 

Case studies from other companies are compelling, but using your own data is even more compelling. If you're a SpeedCurve RUM user, the user engagement charts that are the top of your Performance dashboard are an easy way to illustrate the correlation between performance and bounce rate using your own data. (One thing we've found is that almost everyone can relate to bounce rate as a meaningful metric.)

Fire up people's competitive spirit

One of the fastest routes to getting people to care about performance is to show them how slow their site is compared to their competitors. One of the great things about synthetic monitoring is that you can test any page on the web, not just your own. This lets you do great things like generate side-by-side filmstrips – and even better: videos – of your site alongside your competitors' sites (or any other aspirational sites).

Here's how to set up ongoing competitive benchmarking and generate comparison videos.

Make performance visible

If you want to see non-technical stakeholders' eyes glaze over, show them an endless series of dashboards and charts. Less is more is your mantra. In the same way that you need to understand what motivates different people in your organization, you also need to tailor your reporting. For some people, your performance report might be just a single graph or a very simple dashboard that shows them the data points they care about. (It stands to reason that you should always be ready to go deeper upon request.)

One excellent practice that's used effectively by companies like Lonely Planet and Ticketmaster is to have monitors mounted in open areas of their offices, displaying key performance stats and comparison videos. Lara Hogan (previously director of engineering at Etsy) wrote a great blog post demonstrating how Etsy took advantage of the power of showing versus telling.

Collaborate on performance budgets

Performance budgets are an important tool for ensuring your site is delivering a great user experience. The idea is to identify your most important metrics, then set thresholds for those metrics, and get alerts when those budget thresholds are crossed. 

As mentioned near the top of this post, there's no one-size-fits-all unicorn metric that will get everyone in your company excited about performance. This means there's no one-size-fits-all metric you should focus on for your performance budgets. Instead, your performance budgets can run a gamut that includes:

  • Ops needs to know Time to First Byte so that they can investigate back-end issues.
  • Developers might care about Start Render, because they want to get a sense of how well the page is built – for instance, are there any blocking scripts or stylesheets.
  • Your marketing team wants to know how quickly the page delivers the most important content from a user's perspective, so they might want to track the rendering of hero images.
  • SEO folks want to track Core Web Vitals.

To make people accountable, give them ownership over their performance budgets and make sure they receive alerts when their budgets are exceeded.

Score some easy wins

If you're new to performance – or if you're tackling a site that's new to you – there's a good chance there's some low-hanging fruit you can optimize. The first places to look are images and blocking stylesheets and scripts (especially third parties).

For example, the team at did a one-month performance sprint where the most impactful changes they made were simple image optimizations: they improved image quality and compression, and they fixed an image sprite that was blocking pages from rendering. As a result, they saw a 2-second improvement in median load times and almost doubled their mobile conversions – a really big deal, since more than half their revenue comes from mobile. This relatively easy win was a fantastic way to get performance buy-in throughout their company.


We live in a culture that doesn't celebrate success as much as it should. So consider this a reminder: Every time you move the needle on performance – and that moves the needle on user engagement or revenue or whatever your company cares about – shout it from the rooftop. Or if that's not allowed at your office, email is fine, too.

Here at SpeedCurve, we have a #ring_the_bell Slack channel where we share wins and milestones, both big and small. And in the spirit of Lara Hogan's donut manifesto, we send each other fun gift baskets to celebrate victories. 

Share what you've learned

Shouting from the rooftops (or sending celebratory emails) is a great start. Next, share what you did and what you learned. This can be in the form of company- or department-wide emails, posts on your in-house dev blog, and internal meetups. I know of some performance teams that do regular monthly technical meetups, and once or twice a year do a company-wide event where they share all their greatest web perf stats and victories. 

Membership in a healthy performance culture also means embracing the fact that you're part of a culture that's much bigger than your company. There are so many ways to get involved and to learn from other webperf enthusiasts:
