Clean code assumes the correct use of tags:
<h1> - main heading pages
</h1><h2>–</h2><h6> — subheadings
<p> — text
</p><ul> and <ol> — lists
<strong> - important words</strong></ol></ul></h6>
This structure helps search engines better determine the topic of the page.
4. Improves mobile optimization
Clean code is easier to adapt to mobile devices.
And mobile optimization is one of the important ranking factors.
5. Reduces technical errors
Bad code can cause:
- loading errors
