11 website KPIs every small business should be tracking.

Between GA4, Google Search Console and whatever other analytics software you’re using, there’s a bewildering amount of website data at your fingertips.

This means the challenge isn’t finding website success metrics to track. It’s knowing which ones really matter for your business — and what to do if they’re heading in the wrong direction.

Here, we’ve pulled together the eleven website KPIs that matter most for small businesses. Whether you’re trying to get more enquiries, sell more products or just understand whether your website is doing its job, these are the numbers worth paying attention to.

But first, a quick definition of what we mean by a website KPI.

What are website KPIs?

KPI stands for key performance indicator. In the context of your website, KPIs are the metrics that tell you how well your site is performing.

They tell you whether your website is helping you to achieve your business goals — whether that’s generating more enquiries, driving more sales, attracting more visitors or building your brand.

Tracking the right web KPIs means you can spot website problems early, make informed decisions about what to improve and measure the impact of any changes you make.

The website KPIs you should be tracking as a small business

So which website key performance indicators are worth your time? Here are the ones to stick on your dashboard.

1. Page views

Page views is the total number of times pages on your website have been loaded or reloaded in a given time period. Every time someone opens a page on your site, it counts as one page view.

What it means for your business

Page views give you a broad idea of how much activity your website is generating. A rising trend over time suggests growing interest — more people are finding you and exploring your website content. A sudden slump can signal a technical issue, a loss of search rankings or a drop in marketing activity.

What good looks like

There’s no universal benchmark. It depends on the size and age of your business. What matters most is the direction of travel. Are page views growing month on month? Or are things heading in the opposite direction?

2. Users

This website KPI refers to the number of individual people who have visited your website in a given period. GA4 distinguishes between new users (first-time visitors) and returning users (people who’ve landed on your website before).

What it means for your business

While page views tell you how much activity is taking place across your website, users tell you how many actual people are behind that activity.

Tracking the split between new and returning users is particularly useful. New users tell you how well your marketing and SEO are working. Returning users tell you how interesting or useful people find your products or content.

What good looks like

Ideally, the number of users your website gets will tick steadily upwards as you develop your SEO, content and marketing strategies. Again, your own metrics are the best website benchmark.

3. Traffic sources

Next on our list of website KPIs, we have traffic sources. These sources (also called acquisition channels) show you where your website visitors are coming from — organic search, direct, social media, paid advertising, email or referrals from other websites.

What it means for your business

Understanding your traffic mix tells you which marketing channels are working and which aren’t. If you’re investing heavily in social media but getting next to no traffic from it, that’s worth knowing. If organic search is driving most of your visitors, you have a strong SEO foundation worth protecting.

But remember, a healthy website attracts traffic from multiple sources because reliance on a single channel can leave your business vulnerable.

What good looks like

You want to see traffic sources that are diversified and weighted according to your marketing investment. The traffic sources that drive visitors to your website should reflect your marketing activity.

4. Top pages

Top pages show you which individual pages on your website are receiving the most visits. You can also find out which pages are being used as entry points for new visitors.

What it means for your business

Knowing which pages are doing the most work helps you focus your improvement efforts. A blog post that gets a lot of views should have a clear call to action. A service page that pulls in lots of traffic — but then converts poorly — needs your attention.

What good looks like

Ideally, the pages doing the most work should overlap with the pages that matter most to your business goals. That may be your homepage, your product or service pages, or key landing pages or blog content — anything that gets the clicks or conversions you’re looking for.

If you’re getting most of your traffic from an old blog post that doesn’t really relate to your current business offering, it’s worth revisiting your SEO strategy.

5. Exit pages

Exit pages are the pages where visitors leave your website. This website performance indicator helps you zoom in on the areas of your website that may be causing friction for users.

What it means for your business

People are always going to leave your website at some point. But if they leave after landing on important pages — like your e-commerce checkout, contact page or pricing page — it signals that something may be going wrong.

Exit page data gives you a starting point. It tells you where users might be experiencing problems, so you can dig deeper into the cause.

What good looks like

A high number of exits on a thank-you page or order confirmation is to be expected — that’s the natural end of the website journey. But high exits on a checkout page or contact form are worth investigating.

6. Conversion rate

Conversion rate is the percentage of website visitors who complete an action you want them to complete. That could be making a purchase, submitting an enquiry form, booking a call or signing up to your mailing list.

What it means for your business

This is arguably the most important website KPI for most small businesses.

A high conversion rate means your website is doing its job — turning visitors into customers or leads. A low conversion rate means something is getting in the way, whether that’s unclear messaging, a lack of trust signals or a clunky user experience.

What good looks like

Average conversion rates vary widely by industry and conversion type. For B2B enquiry forms, 2-5% is a reasonable benchmark. For e-commerce, 1-3% is typical.

7. Website speed

Website speed is how quickly your pages load for visitors, typically measured in seconds. Google measures this through Core Web Vitals and PageSpeed Insights — a set of performance metrics that assess real-world website loading times across both desktop and mobile devices.

What it means for your business

Site speed affects everything. Slow pages frustrate visitors, increase bounce rates and hurt your search rankings.

If your site speeds are slow, you should try to make improvements. That might mean optimising images, cleaning up your code, switching hosting providers or getting rid of unnecessary plugins.

What good looks like

Web pages should load in no more than three seconds. For e-commerce websites, users expect pages to load in a speedy two seconds.

8. Average time on page

Average time on page is how long visitors typically spend on a specific page before navigating away or leaving the site altogether.

What it means for your business

Longer time on a page generally means higher engagement — people are reading your content and scrolling down more of the page.

Very short times (under 20-30 seconds) on key pages suggest that visitors aren’t finding what they expected or that the page isn’t holding their attention. Context matters, though. A contact page with a short average time isn’t necessarily a problem if people are going ahead and completing the form.

What good looks like

For blog posts and detailed service pages, two minutes or more is a positive signal. For transactional pages, like checkout or contact, shorter times combined with high conversion rates are also perfectly healthy.

9. Average session duration

Average session duration is how long visitors typically spend on your website across an entire visit, from their first page to their last.

What it means for your business

Longer sessions show that visitors are engaged and exploring your site. They’re reading to the bottom of pages, browsing through multiple pages and considering their options before deciding whether to act.

Very short average sessions (under 30 seconds) suggest your site isn’t compelling enough to hold attention — or that a technical issue is causing people to leave quickly.

What good looks like

Two to three minutes is a solid benchmark for most small business websites. E-commerce sites and content-heavy sites tend to hold user attention for longer.

10. Views per user

Views per user is the average number of pages a single visitor views during their time on your website.

What it means for your business

This website KPI is closely linked to average session duration. It tells you how well your website is at holding the attention of users and guiding them from one page to the next.

A higher number suggests visitors are finding your content engaging — and they have the navigation tools and calls to action they need to move through your site with ease.

If views per user are low, you can look at top exit pages to try to understand what is causing visitors to leave your site before they’ve fully explored your content.

What good looks like

Between 1.5 and 4 pages is typical for most small business websites. E-commerce websites tend to get higher views per user as visitors browse through multiple products.

11. Engagement rate

Engagement rate is the percentage of sessions in which a visitor actively engaged with your website. Active engagement is defined by GA4 as a session lasting longer than ten seconds, involving a conversion event or two or more page views.

Effectively, this KPI is the opposite of bounce rate, which measures the percentage of visitors who left your site without engaging.

What it means for your business

A high engagement rate means visitors are interacting meaningfully with your site rather than arriving and immediately leaving.

A low engagement rate on key pages — your homepage, service pages, product pages — suggests something isn’t resonating. The page may be loading slowly, the messaging may be unclear or the content may not be matching visitor expectations.

What good looks like

An engagement rate of around 60% or higher is a good sign.

Just getting started with website KPIs?

If you’re new to website analytics — and only just getting used to the huge array of site measurement options available — it makes sense to start small:

1. Pick a handful of the website effectiveness metrics above, keeping your business and website goals in mind.
2. Edit your reports so you don’t need to go hunting for your chosen metrics every time you open your website analytics.
3. Set aside some time each week to review your KPIs, comparing them week-on-week and month-on-month.
4. Add more metrics into the mix as your understanding and confidence grow.

Following this approach, you build a sense of how your website is working over time. You can identify areas for improvement and start making website decisions based on evidence rather than instinct.

What are your website KPIs telling you?

Sometimes, your website metrics indicate that your website and business are moving in the right direction. More traffic, more engagement, more conversions.

But it may be that your chosen KPIs tell a different story. They reveal issues with your website that won’t go away, no matter how many tweaks to website content or layout you make.

If your conversion or engagement rates are low, or if your page views have been declining for months, the issue might be rooted in your website’s design or technical foundations.

At Radical, we build bespoke WordPress websites that are designed to perform well against the metrics above. That means fast, technically solid websites with strong UX, clear messaging and the kind of design that builds trust and drives action.

Website KPI FAQs

What are the most important website metrics?

It depends on your goals. For most small businesses, the most important website metrics are conversion rate (are visitors taking action?), engagement rate (are people engaging with your content?) and page views (are people actually visiting your site?).

How often should I review my website KPIs?

At a minimum, review key metrics for website performance once a month. Consistency is really important. Regular reviews make it easier to spot trends and anomalies before they become serious problems.

What tools do I need to track website KPIs?

Google Analytics 4 (GA4) is free and covers most of the metrics in this guide. Google Search Console (also free) is essential for organic search and technical performance data. Google PageSpeed Insights gives you information on website load speed.

Between these three tools, you can access pretty much all the website metrics a small business needs.

But take note! Your website must be set up to collect user data compliantly. Under UK GDPR, collecting data about your website visitors — including analytics data — requires informed consent.

What’s a good conversion rate for a small business website?

For B2B enquiry forms, 2-5% is a reasonable benchmark. For e-commerce, 1-3% is typical.

But these figures vary significantly by industry, traffic source and the specific action you’re measuring. So rather than comparing your website to industry benchmarks, it can be more useful to track your own conversion rate over time. Then, work to improve it.
