Most websites are too slow

Users and search engines demand fast page speed. Google’s own case studies show the importance of improved speeds for SEO and conversion rates.

  • Slow sites face crawl budget issues where less content gets indexed, ranked, and trafficked.
  • Slow sites have higher bounce rates, lower conversion rates, and generate less revenue.

Now you don’t have to be a developer to improve your page speed

The Page Speed dashboard offers more than a dozen controls so you can control your website performance based on its specific needs.

  • Limit the number of HTTP requests required to deliver your site
  • Reduce the number of DNS and TLS handshakes
  • Improve the cache-ability of your website’s resources

What is Page Speed?

Broadly speaking, page speed, or load time, refers to the time it takes to download and display the entire content of a web page in the browser, typically measured in seconds. Page speed should also not be confused with site speed. The former refers to an individual page, whereas the latter refers to a sample of pages on a site.

No metric can fully capture the experience of page speed because the loading of a page is not a single moment in time. There are multiple moments (and corresponding metrics) in the loading process that influence user perceptions. In later sections of this page, we'll talk about different metrics that measure various aspects of page load. Because these metrics only measure a moment in the overall load of a web page, these are typically measured in milliseconds.

Understanding the unique insights offered by each of these page speed metrics is important because it allows you to optimize for the ones most important to your site’s user experience.

Calculating Page Speed

Historically, it's been difficult for webmasters to measure page speed. Most metrics don't fully reflect the user experience.

There is also the issue between lab data and field data. Lab data is website performance data collected in a controlled environment with predefined device and network settings. Field data is website performance data collected from real page loads experienced by actual users. With lab data, you are able to understand conditions on the most typical devices and network settings. With field data, you capture true real-world user experience and enable correlation to business KPIs, but there is a restricted set of metrics to work with.

Metrics that attempt to measure page speed include:

None of these tell the full story in isolation, nor are they reliable on a large scale. DOMContentLoaded, for example, doesn't correspond with what the user sees on the screen and First Contentful Paint, as another example, only captures the beginning of the loading experience.

Because page speed isn't only about serving content either. It's about providing both a visually complete and usable site. Focusing too much on the visuals and neglecting usability can ruin the user experience. That’s why you need to address page speed from the load time and interactivity angle and consider a “concert” of metrics. The interval between having a visually complete page and a usable one can make or break the user experience.

Here are the key metrics for loading speed:

Here are the key metrics for interactivity and usability:

Factors that impact page speed

In order to understand the impact of page speed, let’s review how page load time works:

There are many factors at play when considering page speed. Some of these include:

Page Speed Standards

Page speed standards matter for at least two reasons.

First, users are impatient and have increasingly higher standards about site performance. They typically won’t wait around for more than a few seconds for a page to load and become interactive. And if it doesn’t load or if it isn’t very responsive, they won’t just bounce for that particular session. Oftentimes, they are gone for good - you won’t get a second chance to impress them. Research has shown that the stress response to delays in mobile speed, for example, is greater than waiting in the checkout line at a physical store. Understand that page speed is a foundational aspect of a good user experience. It’s typically the thing a lot of people “feel” about your online brand. Speed often determines whether customers can find your brand, trust your website, and buy from you.

Second, Google is struggling to keep up with an internet that's quickly expanding in size and complexity. They have a limited amount of resources to fulfill their mission of “organizing the world’s information in an accessible and useful way”. That means their time is fleeting on your website. They have a crawl budget. If you want to make the most of it, if you want more pages crawled and indexed, you need to architect a site that loads quickly.

How fast does a web page need to be?

Beyond 2 seconds is extremely slow and will significantly influence page performance. It will also deter users from using the page or getting any information from that page.

Benefits of fast page speed

The benefits are two-fold. Page speed has a significant impact on how thoroughly both users and search engines are able to interact with your website.

Users bounce less, visit longer, convert more, and buy more on sites with fast page speed. Think about the alternative. In the same way that a customer would get frustrated waiting for an employee to help them in a physical store, they get equally (if not more) frustrated waiting for content to load and buttons to respond to their input.

Search engines crawl more pages, discover more content, and index more content on sites with fast page speed. Think about Google’s circumstances. They don’t have the time or resources to stick around to fully crawl and index sites that don’t load quickly.

According to a Google Survey, page speed is the single most important factor in user experience. So, if we look at the results, you’ll see that speed/load time topped other things we often think to be important to user experience “How easy it is to find things on the site” and “website design,” by a considerable amount.

Because speed is so important to user experience, it also has a significant impact on business. Users do not want to wait around for slow websites.

How to improve page speed

Simply put, the more success you have in business, the harder it is to maintain optimal site performance. Code, apps, scripts accumulate and become roadblocks. As brands grow and become more sophisticated, their websites become richer. And richness comes with a price. Performance issues scale as you grow and each issue has a tangible impact on the customer journey, from discovery to browsing to conversion.

Here are some basic level, but high-leverage, best practices to implement on your site to improve page speed:

There are many helpful tools on the internet to find additional recommendations with in-depth directions for solutions. Here are a few that we recommend:

1. The Google Pagespeed Insights Tool.

This tool leverages lab data from the Google Lighthouse Report to generate an “overall” page speed score for your website on desktop and mobile devices. It also leverages field data from the Chrome User Experience Report to generate scores for your Core Web Vitals and whether or not you are passing that assessment. Additionally, there are sections on “Diagnostics” and “Opportunities”, which provide recommendations for how you can improve each of these scores.

2. The Google Lighthouse Report

This tool leverages lab data on six metrics - First Contentful Paint, Speed Index, Largest Contentful Paint, Time To Interactive, Total Blocking Time, and Cumulative Layout Shift - to generate a site performance score for your website. Similar to the Pagespeed Insights tool, there are sections on “Diagnostics” and “Opportunities”, which provide recommendations for how you can improve your score.

3. The Google Chrome User Experience Report

This tool leverages field data on 8 metrics, 4 of which (First Contentful Paint, Largest Contentful Paint, First Input Delay, Cumulative Layout) are displayed in the Pagespeed Insights tool, to measure how well real-world users are experiencing your website.

4. The Google Search Console - Core Web Vitals Report

This report uses field data accumulated from the Chrome User Experience report over the previous 3 month period to track and categorize website URLs based on how well (and whether) they are meeting the new Core Web Vitals requirements. It will be particularly relevant once the .

5. Google Search Console -
Page Experience Report

This report shows the percentage of mobile URLs on your website with a “good” page experience, whether there are any page experience issues detected or “failing” URLs on your website, as well the number of impressions in organic search generated by those “good” URLs. It will be particularly relevant once the Core Web Vitals algorithm update is rolled out this summer.

How to get buy in to improve page speed

Most SEOs understand the importance of page speed. To get buy-in from the rest of the marketing team, web developers from the engineering team, or even the executive team if you are in a larger organization, explain the impact of page space speed on high-level financial goals. Communicate that improved site performance clearly leads to more business. Educate them on the fact that decreased site performance bleeds potential and existing customers, sometimes permanently. Expand on the fact that simple improvements can be quite high-leverage. Google has tons of case studies showing the connection between performance and revenue. You can see a whole list of stats on the relationship between performance and bounce rates and conversions here too.

While you are building your case for site performance projects, be prepared to address the following questions:


Google has been obsessed with page speed for over a decade. In 2010, they made desktop page speed a ranking factor. Then in 2018, they made mobile page speed a ranking factor. And in June 2021, they will be introducing a whole new set of performance-related ranking factors called “Core Web Vitals”.

With that said, there are over 200 ranking factors that make up Google’s algorithm and some have more weight than others. How important is page speed in the mix? It’s less important than the relevance and quality of the page’s content. You could be the fastest website on the internet, for example, but that won’t get you very high in the search engine rankings if the content isn’t great as well. As long as your page speed is in a reasonable range, it’s not going to hurt you.

That said, there are plenty of cases where page speed plays an important role in search results. Imagine a scenario, for example, where two sites are competing for a key industry query, they both have great content on the subject matter, but one loads faster and is more responsive than the other. In that case, page speed would serve as a sort of tie-breaking factor in which result is ranked higher.

Page speed has many indirect effects on search engine optimization as well.

If your site is slow, Google probably won’t put your crawl budget to optimal use. Fewer pages will be crawled. Portions of your website might remain totally unknown to Google. That means new and updated content won’t be discovered and added to search results as frequently, which of course means fewer opportunities to rank, garner impressions, and drive more organic traffic to the site.

Likewise, if your site is slow and unresponsive, users will probably get frustrated, spend less time on pages, visit fewer pages, bounce more often, convert less often, and are less likely to return ever again to find information or do business. Google considers a lot of these metrics in their algorithm too.

As mentioned earlier, page speed has renewed interest in the SEO community given the rollout of the Core Web Vitals update in the summer of 2021. New metrics - Largest Contentful Paint, First Input Delay, and Cumulative Layout Shift - are being introduced to measure the quality of a site’s user experience. Now, webmasters will have to focus improvements around how quickly the most important content in the initial window appears, how responsive buttons and links are, and how visually stable the page remains as new elements are loaded.

What you'll learn in this video

  • How page speed impacts business
  • How to define page speed
  • Factors that impact page speed
  • Key metrics to focus on for user experience
  • The impact of page speed on SEO

Hello everyone, Ryan here, and today we're going to be talking about Page Speed.


What do you need to know about PageSpeed specifically in regards to the upcoming 2021 Google algorithm update?

A couple of things that we'll learn in this video is how PageSpeed impacts business. What page speed means the key loading metrics to focus on for user experience, and the impact of page speed on SEO. So to start off, how important is this to your users? Well, we took a couple of samples from a couple of studies, and the time that it takes to load the page is about 75% of the experience from users. So, if you look at the other metrics like how easy it is to find what you're looking for, how well the site is to screen, and those all have a smaller impact, the speed of the page actually loading on the device that the user is using.


How it impacts business

As speed goes from say one to three seconds to load the probability of a bounce increases only 32%. Now, if it takes up to five seconds, you're at 90%, six seconds, you're at 106%, and 10 seconds you're at 123%. So you can really see the impact that it has on the bounce rate for users going to your site.

Defining Load time

Here, we're looking at a screenshot from something called Google Lighthouse. WPC says (that's the business that kind of runs the internet) "Load is not a single moment in time, it's an experience that, not even one specific connection metric can capture," and there are multiple moments during that load experience that can affect how fast or how slow user perceives the page to be. Here are some of those metrics, especially the ones that Google looks at (specifically Google Lighthouse).

First contentful paint is how long it takes for the first element on the page to load. So, like, the title text content, etc. Now the next three that we're looking at specifically affect the upcoming Google algorithm update that focuses on the usability of the website. The first is the first input delay. That means how long does it take between the time you click on something — specifically like interacting on the page — and the time that it takes that page to interact with your click.


The next one is the largest contentful paint. That means how long does it take for the largest element on the page to load — whether it's an image, a background, a video, or something like that. And then loading stability also known as cumulative layout shift. Do those elements on the page move around as the page loads from an ad or something like that? You'll notice that Facebook's browser is really bad at this. When you click on an article and you're scrolling on your phone. It takes forever to actually get those ads to pop up, and can potentially cause a really bad experience if you're going to click on something and you click on an ad that you didn't want to. So, that's a very, very important one.


Okay, so there are certain thresholds for each one of those items that we just looked at, and the thresholds for those actually loading. Here we see a chart where it shows on the left-hand side you can see first Contentful paint, first input delay, largest contentful paint, and the cumulative layout shift. Those can be measured in either milliseconds or seconds, and you can see on the chart here that, for example, first Contentful paint, a good score is zero to 1000 milliseconds, a poor score is over 3000 milliseconds so you take a look at this chart here, if that's something that you're really trying to focus on this kind of gives a good overall example of how fast they need to be to get a good Lighthouse score.


PageSpeed and SEO

So Google had Google's already made speed, an SEO ranking factor. It first became official in 2010 for desktop and then in 2018, Google changed their algorithm to include that for mobile as well. Now, upcoming in May the core web vitals, that's going to be a major ranking factor now we don't know how much of a ranking factor, but it's a good time. Usually when Google says, a year in advance, that they're going to have a major update on this, that's gonna be a pretty big ranking factor. What's going to happen with those fast websites is that they're gonna rank higher and get more organic traffic than slow ones, simply because of that user experience.


So how does, how come by actually work with the PageSpeed, so Google allocates a limited time, which they refer to as a crawl budget for each website. So, a fast loading time means that Googlebot doesn't have to spend as much time on your website to get the same amount as say another website or even more. And that's what PageSpeed will do so the faster loads, the more your content gets scanned by Google and the more keywords you rank for, and hopefully the more organic traffic you get.


So remember, PageSpeed isn't just a technical problem, it's a business problem and that's a quote from Google. So this is what we've learned in the video today is how PageSpeed impacts business, what PageSpeed means the key metrics to focus on for user experience, and the impact of PageSpeed on SEO. Now, we do have another video showing how to buy software, and how easy it is to implement PageSpeed, so feel free to take a look, we've got a link to it in this video. Thanks for watching, we'll see you soon.



Broadly speaking, page speed refers to the time it takes to download and display the entire content of a page in the web browser, typically measured in seconds. No metric can fully capture the experience of page speed because the loading of a page is not a single moment in time. There are multiple moments (and corresponding metrics) in the loading process that influence user perceptions


Page speed matters for SEO because it’s a Google search ranking factor on mobile and desktop devices. It will become even more important in the summer of 2021 when Google rolls out the “Core Web Vitals” update, which adds new user experience ranking factors to its algorithm as well.


Google measures page speed based on a variety of metrics using lab data from the Google Lighthouse report and field data from the Chrome User Experience report.


From a user standpoint, improving your page speed has been shown to reduce bounce rates, increase the length of site sessions and number of page views, improve conversion rates, and increase revenue. From a search engine standpoint, improving your page speed has been shown to help Google discover and index more new and updated content from your website in a given crawling session.


Start by plugging your website into Google tools and reports like Pagespeed Insights and Lighthouse to see the improvements you need to make and the associated suggestions for how to make them. Google does a good job of leading you to page speed best practices in these tools and reports. If you wish to optimize the entire process, consider using a software solution like Huckabuy Page Speed.
