10 things to check on my website before spending a single euro on advertising

The 10 questions

1. Q1Question 1 : Can someone who sees my home page for 5 seconds tell 2 things out of 3: what I do, for whom, and where?

   Yes No

   Why: A visitor who doesn't understand leaves without looking further.

   How to check: Show your home page for 5 seconds to someone who doesn't know your business, hide the screen, then ask them what you do, for whom and where.

2. Q2Question 2 : On my phone, can I see a button or my phone number without scrolling?

   Yes No

   Why: What isn't seen never gets clicked.

   How to check: Open your website on your phone without touching the screen: is a call or contact button, or your number, visible straight away?

3. Q3Question 3 : From any page, can people reach me in 1 click, and are my legal name, address and company number visible?

   Yes No

   Why: A hesitant customer wants to know who they are dealing with; these details are also mandatory.

   How to check: Open 3 pages at random: is there a call or contact link, and can you find your legal name, address and company number (e.g. Belgian enterprise number, French SIREN), for instance in the footer?

4. Q4Question 4 : Can my form be completed in under 60 seconds on a phone, with 5 fields maximum, and does it arrive in under 5 minutes?

   Yes No

   Why: A broken form loses customers without you ever knowing.

   How to check: Fill in your form on your phone while timing yourself, then note how long the message takes to reach your inbox (check the spam folder too).

5. Q5Question 5 : Does PageSpeed Insights show a mobile LCP of 2.5 seconds or less?

   Yes No

   Why: A slow website loses visitors before it even appears.

   How to check: Go to pagespeed.web.dev, paste your website address, choose the “Mobile” tab and read the “Largest Contentful Paint” value. If real-user data is shown, read that first.

6. Q6Question 6 : Can I read and tap everything on my phone without zooming or scrolling sideways?

   Yes No

   Why: Google indexes the mobile version of your website first, and a customer who has to zoom may give up.

   How to check: Go through your whole website on your phone: text is readable without zooming, nothing sticks out to the side, and every button or link can be tapped without hitting the next one (about 48 pixels).

7. Q7Question 7 : Does each service I sell have its own page (or, on a one-page website, its own section), with a starting price and a lead time?

   Yes No

   Why: Customers look for a specific service; a general page doesn't answer them.

   How to check: List the services you sell, then look for a page (or a section with its own heading) dedicated to each one, with a price (“from €…”) and a lead time (“call-out within 48 h”, “delivered in 10 days”).

8. Q8Question 8 : Does my website show at least 3 reviews less than 12 months old and 3 photos of real jobs?

   Yes No

   Why: Without proof, customers only compare prices.

   How to check: Count the reviews on your website dated within the last 12 months and the photos of your own work (not stock photos).

9. Q9Question 9 : When I search for “my trade + my town” in a private window, am I on page 1 (website or Google Business Profile)?

   Yes No

   Why: Customers who don't know you yet find you through search.

   How to check: Open a private browsing window, type your trade and your town (for example “plumber Namur”) and look at the whole first page, map included.

10. Q10Question 10 : Can I say how many enquiries my website brought me last month?

    Yes No

    Why: Without a number, you can't know what to fix.

    How to check: Go back over last month's calls, emails and messages: can you tell which ones came from the website? If you can't know, the answer is no.

Your result

– / 10

Answer the questions: your level appears here.

1. Your level 0 to 3 yes

   Your website is not ready to receive visitors. An ad would pay for clicks that won't turn into enquiries. Start by fixing Q2, Q3 and Q4: they are the quickest.

2. Your level 4 to 7 yes

   The basics are there, but leaks are costing you enquiries. Fix one point a week, starting with questions 1 to 4, which directly affect whether people call you.

3. Your level 8 to 10 yes

   Your website can take paid traffic. Test a small campaign and count the enquiries (Q10) before increasing the budget.
