On-Page SEO Guide: Optimise Every Page for Google

What Is On-Page SEO?

On-page SEO refers to optimisations made directly to a webpage to improve its ranking in search results. Unlike off-page SEO (backlinks, social signals), on-page SEO is entirely within your control.

Title Tag: The Most Important On-Page Element

The title tag appears in search results as the blue clickable headline. It is the single most important on-page SEO element.

Best practices:

Length: 50-60 characters (anything longer gets truncated in search results)

Include primary keyword: Preferably near the beginning

Make it compelling: It is an ad for your page — it needs to earn the click

Unique for every page: Never use the same title on multiple pages

Good: "How to Compress PDF Without Losing Quality — Lazyblink"

Bad: "Lazyblink - Free PDF Compressor Tool Online Web Page"

Meta Description

Not a direct ranking factor, but affects click-through rate from search results.

Length: 150-160 characters

Include target keyword naturally

Describe what the page delivers — write for the reader, not the algorithm

Include a call to action

Heading Structure (H1, H2, H3)

One H1 per page — your main topic, includes primary keyword

H2s for major sections — include secondary keywords naturally

H3s for sub-points — more detail within H2 sections

Good heading structure helps readers and crawlers understand page organisation.

URL Structure

Short, descriptive, keyword-containing URLs rank better than complex ones.

Good: lazyblink.com/how-to-compress-pdf

Bad: lazyblink.com/page?id=1234&cat=pdf&tool=compress

Use hyphens, not underscores. Lowercase only. Reflect the page content.

Internal Linking

Link from high-authority pages to pages you want to rank. Link from related articles to tool pages. Use descriptive anchor text (not "click here"). 3-5 internal links per article is reasonable.
