What Is Conversion and Why Your Site Isn't Selling

You have a website. People visit it. But nobody buys, nobody calls, nobody writes in. Sound familiar? If yes, the problem is almost certainly conversion. Or more precisely, the lack of it.

Last year we worked with a client who had 500 visitors a day and zero inquiries. Literally zero. It turned out his contact form had 11 fields, including "company tax ID" and "preferred method of communication". We trimmed it down to 3 fields and inquiries jumped from 0 to 8-12 per day. Same traffic, same site, dramatically different result.

That is conversion in action. And in this article I will explain what it actually is, how it is measured and, most importantly, why your site is probably not converting well enough.

What is a conversion, exactly?

A conversion is when a visitor on your site does something you want them to do. That simple.

Most people think "conversion = sale", but it does not have to be. Here is what a conversion can be depending on the type of site:

There is also a difference between micro-conversions and macro-conversions. The macro-conversion is the final goal - the purchase, the signed contract. Micro-conversions are the steps along the way - clicking a button, watching a video, adding to cart. Both matter, because if people do not make micro-conversions, there is no way to reach a macro-conversion.

How do you calculate conversion rate?

The formula is dead simple and a surprising number of people do not know it:

Let us say you run a web services business. Last month you had 2,000 visitors and 50 of them filled in the contact form. Your conversion rate is:

Sounds low, right? But for most industries it is perfectly normal. The question is whether you can push it up. Even half a percent extra can mean tens of thousands of euros a year for a larger business.

One important note: do not look only at the overall conversion rate. Break it down by channel - organic traffic, paid ads, social, direct. You will almost always find that one channel converts significantly better than the rest. That is the channel to invest more in.

What is a "normal" conversion rate?

"Normal" depends entirely on the industry, the type of site, and what exactly you are measuring. Here are typical ranges - treat them as ballparks, since they vary a lot by source and methodology (Unbounce and IRP Commerce):

If you are below the average for your industry, you have a problem to fix. If you are around the average, fine, but you can do better. If you are in the top 25%, you are doing something right, but there is always room to improve.

One thing many people overlook: do not chase the number blindly. A 10% conversion rate means nothing if you are attracting the wrong people. A 3% conversion from visitors who are genuinely your target audience beats 8% from people lured in with clickbait who then bounce.

Why is your site not converting? 7 reasons

OK, you now know what conversion is and how to measure it. Now let us get to the real question - why people land on your site and leave without doing anything.

1The site loads slowly

Do you know the first thing I test when a client says "I have traffic but no sales"? Speed. And in 60-70% of cases, that is where a big part of the problem lives.

Data from Google (2016) is clear: 53% of mobile users abandon a site that takes more than 3 seconds to load. And Portent found that a site that loads in 1 second converts 3 times more than one that loads in 5 seconds.

We wrote about this in detail in the article on site speed and how it affects sales, but for a quick test, open PageSpeed Insights and see your score.

2No clear CTA (call to action)

You open a site and... what are you supposed to do? It is not clear. There is no button saying "Order", "Contact us" or "Sign up". Or there is one, but it is hidden at the bottom, in a grey color, in 10px font.

The CTA button is arguably the most important element on the page. Research from HubSpot (330,000+ CTAs, HubSpot's own data) found that personalized CTAs convert 202% better than standard ones. And action- and benefit-oriented copy - "Get a free quote" instead of "Submit" - reliably outperforms generic button text.

3Confusing navigation

I have seen menus with 15 links, dropdowns nested 3 levels deep, and page names that mean nothing to the user. "Solutions", "Platform", "Resources" - that may be clear to developers, but for the regular person trying to figure out whether you repair washing machines in their town, it is meaningless.

Navigation has to be simple enough that your grandmother can find the contact form. That is not a joke - it is the real standard. If someone has to "think" about where to click, you have already lost them.

4It does not work well on mobile

In Bulgaria around 58% of web traffic comes from mobile devices (StatCounter, 2026). If your site does not look and work perfectly on mobile, you are losing more than half of your potential customers.

And "works on mobile" does not mean "displays on mobile". It means: the text is readable without zoom, buttons are big enough for a thumb, forms are easy to fill in, and nothing pushes off the screen. If a person has to pinch and drag the screen to place an order, they will not order. They will go to a competitor. We wrote about this in detail in the article on why mobile matters.

5No trust signals

Why would someone hand over their money or personal details if you do not inspire any trust? People are sceptical online, and rightly so.

Here is what is missing on most sites that do not convert:

• No reviews from real customers
• No SSL certificate (the address is http:// instead of https://)
• No real photos - only stock images
• No physical address, phone, or team information
• No partner or client logos

Research from Baymard Institute shows that 19% of people abandon a purchase because they do not trust the site with their credit card details. And you do not have to be an online store - even with a contact form people wonder "are these guys legit".

6Too many steps to the goal

Every extra step between "I want to buy" and "I bought" loses people. Baymard Institute analyzed 50 cart-abandonment studies and found that on average 70.22% of online carts are abandoned. One of the main reasons? A long, complicated checkout.

The same applies to contact forms. Remember the client with 11 fields? Every field you add increases "friction". The more a person thinks "wait, I need that too", the more likely they are to close the tab. Ask yourself: what is the absolute minimum I need to start a conversation with this person? Usually that is a name, email or phone, and what they are looking for. That is it.

7Wrong traffic

This one is sneaky, because at first glance everything looks fine - you have traffic, the site works, but no conversions. The problem? People are coming who are not looking for what you sell.

I see it most often with people who do their own SEO and target high-volume keywords without thinking about the intent behind them. If you sell accounting services and you rank for "what is VAT", you will get traffic from students writing a paper. They will never become your customers.

That is why it is more important who visits your site than how many people show up. 200 visitors from the right audience > 5,000 random people.

How do you improve conversions? Practical steps

I am not going to give you generic "make your site better" advice. Here are concrete things you can do this week:

The key here is: do not try to change everything at once. Pick 2-3 things from the list, do them, measure the result, then move on to the rest. CRO (conversion rate optimization) is a process, not a one-time event.

Tools for tracking conversions

You cannot improve something you do not measure. Here is what we use and recommend:

If you have the budget, I would also recommend VWO for more serious A/B testing and Crazy Egg for scroll maps. But for most small and medium businesses the four free tools above are perfectly sufficient.

Conversion is not magic - it is engineering

If anything has become clear to me over the years, it is that a good conversion rate does not come from "cool design" or "modern technology". It comes from understanding what the user wants and removing everything standing between them and that goal.

Sometimes that means rebuilding the whole site. But more often it means stripping 8 fields off the form, placing the button where people actually look, and stopping the wrong traffic at the door.

Start with the data. Install Analytics and Clarity, watch what people do on your site, and act from there. Do not guess - measure and improve.
