On-Page SEO: A Beginner’s Guide with Examples

By Suman, Founder, Digital Agency Delhi (Rohini, New Delhi)

On-page SEO means improving the parts of a web page you control so Google understands it and users like it. It includes the title tag, meta description, headings, content, images, internal links and URL. Good on-page SEO matches one page to one search intent and answers it clearly.

What is on-page SEO?

On-page SEO is the work you do on a page to help it rank for the right search. It is different from off-page SEO, which is about backlinks and mentions on other websites.

The good part is that on-page SEO is fully in your control. You do not need anyone else’s permission to improve your title, rewrite a heading or add a helpful table.

If you have not set up the basics yet, go through our SEO checklist for small business websites first. Then use this guide for each important page.

Which parts of a page matter most for on-page SEO?

The title tag, the main heading and the first few lines matter most. They tell Google and the reader what the page is about.

Element	What to do	Example
Title tag	Keyword near the start, under 60 characters	Physiotherapy Clinic in Rohini – Home Visits Available
Meta description	Clear benefit and action, under 155 characters	Book a home visit physio in Rohini. Call today.
H1	One per page, matches the topic	Physiotherapy Clinic in Rohini
H2s	Questions or main sub-topics	What conditions do we treat?
URL	Short and readable	/physiotherapy-rohini/
Images	Named files and alt text	physio-session-rohini.jpg
Internal links	Link to related services	“back pain treatment” linking to that page

How do you write content that ranks with on-page SEO?

Write content that answers the search better than other pages, in simple words. Google rewards helpful pages, not long pages full of keywords.

Follow these steps:

1. Search your keyword on Google and see what type of pages rank: guides, service pages or lists.
2. Note the common questions in “People also ask”.
3. Answer the main question in the first two or three lines.
4. Use one H2 for each important question.
5. Keep paragraphs short, two to four lines.
6. Add a table, checklist or steps where they help.
7. Add real experience: what you see in your own work.
8. End with a clear next step, like a call or form.

In our work with Delhi clinics and shops, the single biggest on-page fix is usually rewriting the first paragraph. Many pages start with “Welcome to our website” instead of saying what they do and where.

How should you use keywords on the page?

Use your main keyword in the title, H1, first paragraph and a few natural places. After that, use related words and variations instead of repeating the same phrase.

For a page on “AC repair in Pitampura”, related words are “split AC service”, “gas filling”, “same-day visit” and “Pitampura and Rohini”. These help Google understand the topic fully.

Avoid keyword stuffing. If a sentence sounds strange when read aloud, it is probably stuffed. Google’s SEO Starter Guide also warns against this.

How do images and internal links help on-page SEO?

Images help users, and internal links help Google find and connect your pages. Both are easy wins.

For images:

• Compress files so pages load fast on mobile.
• Use names like “dental-clinic-nsp.jpg”, not “IMG_2045.jpg”.
• Write alt text that describes the image in a few words.

For internal links:

• Link from blogs to the related service page.
• Use clear anchor text, like “local SEO services”, not “click here”.
• Link new pages from older, popular pages so Google finds them faster.

What on-page SEO mistakes should you avoid?

The common mistakes are duplicate titles, thin content and pages competing for the same keyword. Each one confuses Google.

• Same title on many pages.
• Two pages targeting the same keyword.
• Very short service pages with only a few lines.
• Hidden text or tiny fonts with keywords.
• Missing contact details on service pages.
• Broken links after changing URLs.

Fix these, then review your on-page SEO every few months. Small updates to old pages often bring quicker gains than writing new ones.

Frequently Asked Questions

What is the difference between on-page and off-page SEO?

On-page SEO is everything you change on your own page, like titles, headings, content, images and internal links. Off-page SEO happens outside your site, mainly backlinks, mentions and reviews. Both matter, but on-page SEO is the first step because it is fully in your control.

How many keywords should one page target?

Target one main keyword per page, plus a few related phrases that share the same intent. If two keywords need different answers, make two pages. Targeting many unrelated keywords on one page usually weakens it for all of them.

How long should a page be for on-page SEO?

There is no fixed length. A page should be long enough to fully answer the search. Service pages often work well with 600 to 1,000 helpful words, while guides may need more. Focus on usefulness, not word count.

Does meta description affect rankings?

The meta description is not a direct ranking factor, but it affects clicks. A clear, helpful description can increase the number of people who click your result, which brings more visitors. Google may sometimes rewrite it using text from your page.

Can I do on-page SEO on WordPress myself?

Yes. Plugins like Rank Math or Yoast let you edit titles, meta descriptions and check basics. You can rewrite headings and content in the editor. For a detailed review, contact Digital Agency Delhi on 098705 93623 for a free SEO audit.
