Introduction: The SEO Mistake That Costs Traffic
You’ve built a website.
It looks good.
Content is solid.
Yet rankings aren’t where they should be.
Here’s the twist
👉 Even the best content struggles if the on-page SEO isn’t optimised.
What most web developers don’t realise is that small technical tweaks on each page can dramatically improve rankings, traffic, and conversions.
And while you’re waiting?
Your competitors may already be optimising their on-page SEO efficiently.
Let’s fix that.
What Is On-Page SEO? (Simple Definition)
On-page SEO refers to all the measures you take directly on your website pages to help search engines understand your content and improve rankings.
For developers, this includes:
- HTML and CSS structure
- Headings and meta tags
- Internal linking
- Schema markup
- Page speed optimisation
- Mobile-friendly design
Simply put: making each page clear, fast, structured, and user-friendly for both Google and visitors.
