On-Page SEO Checklist: 20 Must-Do Optimisations for Every Page

Last month, a real estate developer from Wakad called us at Webcomp Digitex. He’d spent ₹3.2 lakhs on a new website. It looked beautiful. The navigation worked perfectly. The property photos were stunning.

But after three months live, he was getting maybe 40 organic visitors a month. His competitor down the road—with an older, frankly uglier website—was getting 1,200.

We ran the site through Screaming Frog. The problem became clear in about ten minutes. Every single page had the same title tag. “Welcome to [Company Name].” No meta descriptions. Images named “IMG_4738.jpg” and “final-final-v3.png”. H1 tags wrapped around the logo. The whole thing.

Beautiful design. Zero search engine optimization in digital marketing terms.

Here’s what happened after we fixed it: Within four months, organic traffic hit 980 visitors monthly. Three property inquiries a week started coming through the contact form instead of one every two weeks.

And look, that’s the thing about on-page SEO. It’s not sexy. Nobody’s going to congratulate you on writing a good meta description at a dinner party. But it’s the foundation everything else sits on. You can’t build traffic without it.

This checklist covers the 20 things we check on every single page we optimise. Not theory. The actual stuff we do for manufacturing clients in Chakan, healthcare practices in Baner, and e-commerce stores across Pune.

Why On-Page SEO Still Matters More Than You Think

I know what you’re thinking. “Isn’t SEO just about backlinks now? Doesn’t Google use AI to figure out what my page is about?”

Yes and no.

Google’s gotten smarter. But it still relies on clear signals to understand your content. Think about it this way: if you hand someone a book with no title, no chapter headings, and no page numbers, they can probably figure out what it’s about eventually. But why make them work that hard?

Here’s something I’ve noticed after working with over 80 businesses in Pune: most companies get on-page SEO maybe 40% right. They have title tags, sure. Maybe even decent content. But they miss the details that actually move the needle.

That real estate developer I mentioned? His competitor wasn’t doing anything magical. They just had the basics locked down. Every page told Google exactly what it was about. Every image had a descriptive alt text. The site structure made sense. That’s it.

When we work on digital marketing SEO at Webcomp Digitex, on-page optimisation comes first. Before we pitch guest posts or build citations or touch paid ads. Because if your pages aren’t optimised, you’re trying to fill a bucket with holes in it.

The 20-Point On-Page SEO Checklist We Use for Every Page

Let me walk you through exactly what we check. This is the same checklist our team uses whether we’re optimising a product page for an e-commerce client in Kharadi or a service page for a manufacturing company in Pimpri-Chinchwad.

1. One Clear H1 Tag Per Page

Your H1 is your headline. The main thing the page is about. You should have exactly one per page.

Not zero (I’ve seen this more times than I can count). Not three. One.

And it should include your primary keyword naturally. If your page is about “CNC machining services in Pune,” your H1 might be “Precision CNC Machining Services in Pune” or “CNC Machining for Manufacturing Companies in Pune.”

Here’s what I mean: We worked with a healthcare clinic in Hinjewadi that had their logo wrapped in an H1 tag on every page. Their actual page headline was just regular paragraph text. Google couldn’t tell what the page was actually about. We moved the H1 to the real headline. Organic clicks went up 34% in five weeks.

2. Title Tag Under 60 Characters

Your title tag is what shows up in Google search results. It’s the blue clickable link.

Keep it under 60 characters or Google cuts it off with “…”

Include your primary keyword near the beginning. But write for humans first. “Affordable Digital Marketing SEO Services in Pune” is better than “Digital Marketing SEO Pune Services Cheap Best.”

Every page needs a unique title tag. Don’t use the same one across multiple pages. That’s like having ten books with the same title on different topics.

3. Compelling Meta Description Under 160 Characters

Your meta description is the snippet of text below your title in search results. Google doesn’t use it for rankings directly, but it absolutely affects whether people click.

Use your primary keyword once. Then focus on giving people a reason to click. What will they get from reading this page?

Bad: “We offer SEO services to help your business grow online with proven strategies.”

Better: “Cut your cost-per-lead by 40% with on-page SEO fixes that actually work. Real examples from Pune businesses.”

4. URL Structure That Makes Sense

Keep URLs short and readable. Include your primary keyword if it fits naturally.

Good: webcompdigitex.com/on-page-seo-checklist-20-must-do-optimisations-for-every-page

Bad: webcompdigitex.com/p?=12847&cat=blog&id=seo

Use hyphens between words, not underscores. Keep it lowercase. And once you publish a URL, try not to change it. If you must, set up a 301 redirect from the old URL to the new one.

5. Strategic Keyword Placement in First 100 Words

Your primary keyword should appear in your opening paragraph. Not five times. Once or twice, naturally.

This tells both Google and your readers what the page is about right away. But don’t force it. “Digital marketing SEO is important for digital marketing SEO success because digital marketing SEO works” sounds like a robot wrote it.

6. Headers That Structure Your Content (H2, H3, H4)

Use header tags to break up your content into scannable sections. Your H2s are your main sections. H3s are subsections within those. H4s are rare—you probably don’t need them.

Include keywords in some of your H2s, but don’t stuff them everywhere. “On-Page SEO Best Practices” is fine. “Best On-Page SEO Tips for SEO Success in SEO” is ridiculous.

Headers help readers scan. They also help Google understand how your content is organized. Win-win.

7. Keyword Density Between 1-1.5%

This one’s simple. Your primary keyword should make up about 1 to 1.5% of your total word count.

In a 2,000-word article, that’s 20-30 times. But honestly, don’t count. Just write naturally and check it later with a tool like Yoast or Surfer SEO.

Too few mentions and Google might not understand what you’re targeting. Too many and you’re keyword stuffing. Neither helps.

8. Internal Links to Related Content

Link to other relevant pages on your site. Three to five internal links per page is a good baseline.

This helps Google discover your other pages. It keeps visitors on your site longer. And it helps you direct “link juice” to pages you want to rank.

A real example: We worked with an e-commerce client selling industrial tools. They had great product pages but no internal linking strategy. We added links from their blog posts to relevant product categories and from product pages to related products. Organic revenue from search went up 28% in three months just from better internal linking and on-page tweaks.

Make your anchor text descriptive. Not “click here”—that tells Google nothing. Use “check out our guide to content marketing” or “see our CNC machining services page.”

9. External Links to Quality Sources

Link out to 2-3 high-quality external sources when relevant. Government sites, industry authorities, research papers, well-known publications.

This might sound counterintuitive—why send people away? But it shows Google you’re connected to the broader web of information. You’re citing sources. You’re not just making stuff up.

Just make sure they open in a new tab so people don’t leave your site completely.

10. Image Alt Text That Describes the Image

Every image needs alt text. This is the text that screen readers use for visually impaired visitors. It’s also what Google “sees” since it can’t actually look at images the way we do.

Describe what’s in the image. Include your keyword if it makes sense, but only if it actually describes the image.

Good: “Digital marketing team reviewing on-page SEO metrics in Google Analytics 4”

Bad: “digital-marketing-seo-digital-marketing-digital-marketing-seo”

Also bad: Leaving it blank or using “image123.jpg”

11. Compressed Images for Fast Loading

Large image files slow your page down. Slow pages kill your rankings and frustrate visitors.

Compress every image before uploading. We use TinyPNG or ShortPixel. Aim for under 200KB per image for most website uses.

And use the right format. JPG for photos. PNG for graphics with transparent backgrounds. WebP for everything if your site supports it—it’s smaller and faster.

12. Mobile-Friendly Design

Over 60% of searches happen on mobile. If your page looks terrible or loads slow on a phone, you’re done.

Check your site in Google Search Console under “Mobile Usability.” Fix any errors. Test it yourself on your phone. Can you read the text without zooming? Are buttons big enough to tap? Does everything load?

This isn’t optional anymore. Google’s been mobile-first for years.

13. Page Load Speed Under 3 Seconds

Google cares about Core Web Vitals now. Largest Contentful Paint (LCP), First Input Delay (FID), Cumulative Layout Shift (CLS)—these are real ranking factors.

Run your page through PageSpeed Insights. Aim for a score above 80 on mobile. Fix the issues it flags: compress images, remove unused JavaScript, enable caching, use a CDN.

Here’s the reality: a manufacturing client in MIDC came to us with a page that took 8 seconds to load. Their bounce rate was 76%. We got it down to 2.4 seconds. Bounce rate dropped to 48%. Organic conversions doubled.

Speed matters.

14. Schema Markup Where Relevant

Schema markup is code that helps Google understand specific types of content. Reviews, recipes, local businesses, products, events, FAQs—there’s schema for most content types.

Use Google’s Structured Data Markup Helper to add it. Then test it with the Rich Results Test tool.

Does schema help rankings directly? Maybe a little. Does it help you get rich snippets in search results—star ratings, FAQ dropdowns, price info—that make people more likely to click? Absolutely.

15. Unique, Valuable Content Over 800 Words

Thin content doesn’t rank. If your page has 150 words of generic fluff, it’s not beating a competitor with 2,000 words of genuinely useful information.

Aim for at least 800 words on most pages. More for pillar content or competitive keywords. But length alone isn’t enough. The content has to actually help people.

Don’t write “SEO content.” Write content that answers questions, solves problems, or teaches something useful. Then optimise it for SEO.

16. Clear Call-to-Action

What do you want visitors to do after reading your page? Tell them.

“Get a free SEO audit—call +91-9960802498”

“Download our on-page SEO checklist”

“Schedule a consultation”

Make it specific. Make it visible. And make it easy to take the next step.

We’ve seen conversion rates double just by adding a clear, prominent CTA to pages that didn’t have one before.

17. Updated Publication Date

Google likes fresh content. If your page shows a publication date, keep it updated when you revise the content.

This is especially important for guides, tutorials, or anything with time-sensitive information. A blog post from 2018 that hasn’t been touched signals “this might be outdated.”

Update your content every 6-12 months. Refresh stats, check links, add new sections. Then update the date.

18. Clean Code Without Errors

Broken HTML, unclosed tags, excessive inline CSS—messy code can confuse search engines and slow down your site.

Run your page through the W3C Markup Validator. Fix critical errors. You don’t need a perfect score, but glaring problems should be cleaned up.

At Webcomp Digitex, we’ve seen cases where broken schema markup or duplicate meta tags were actively hurting rankings. Clean them up and rankings improved within weeks.

19. HTTPS Security Certificate

This should be a given by now, but I still see HTTP sites. Google’s been pushing HTTPS for years. It’s a ranking signal. And browsers show “Not Secure” warnings on HTTP sites, which scares visitors away.

Get an SSL certificate. Most hosts offer them free. Switch your site to HTTPS. Make sure all internal links point to the HTTPS version. Set up redirects from HTTP to HTTPS.

20. Readable Content with Short Paragraphs

Write for humans, not for algorithms. Use short paragraphs. Vary sentence length. Include subheadings every 300 words or so.

Read your content out loud. Does it sound natural? Or does it sound like you’re trying to trick a robot?

We do SEO copywriting service work for clients who say “we tried writing SEO content ourselves and it sounded terrible.” That’s usually because they focused on keywords instead of clarity.

Write clearly first. Optimise second.

How We Actually Use This Checklist at Webcomp Digitex

Look, I could hand you this list and you could spend three days optimising one page. That’s not practical if you have a 50-page website.

Here’s how we prioritise:

First, we identify the pages that matter most. Usually your homepage, key service pages, and top blog posts. Those get the full 20-point treatment.

Then we tackle the quick wins on other pages. Title tags, meta descriptions, headers, image alt text. These take minutes per page and make a real difference.

The technical stuff—schema markup, page speed, clean code—we often batch. Fix them once across the whole site.

And honestly? You don’t have to be perfect. We’ve gotten clients real results with pages that scored maybe 75% on this checklist. But they nailed the fundamentals: clear titles, good content, fast load times, mobile-friendly design.

I’m not saying skip stuff. I’m saying start with what moves the needle, then go back for the details.

The Part Nobody Talks About: Maintenance

Here’s something that only comes from actually doing this work: on-page SEO isn’t a one-time thing.

Google’s algorithm changes. Your competitors improve their pages. Your content gets outdated. Rankings slip.

We audit our clients’ pages every quarter. Not every page, but the important ones. We check:

• Are title tags still optimised?
• Has the content gotten stale?
• Are there new keywords worth targeting?
• Is page speed still good after adding new images or plugins?
• Are internal links still working?

A healthcare client in Baner had a page that ranked #3 for a valuable keyword. Over six months, it dropped to #11. We ran through this checklist again. Updated some stats. Added a new section. Compressed a few images that had been slowing things down. Two months later, back to #4.

Maintenance matters.

Real Results from Following This Checklist

That real estate developer from the beginning? Here’s what we did:

Rewrote all title tags and meta descriptions to be unique and descriptive. Added proper H1 tags to every page. Renamed and added alt text to 87 images. Restructured content with clear H2 and H3 headers. Added internal links between property listings and neighborhood guides. Compressed images, which cut page load time from 6.2 seconds to 2.1 seconds.

We didn’t build a single backlink. We didn’t run ads. We didn’t rewrite all the content (though we did expand a few pages).

Four months later: organic traffic went from 40 visitors a month to 980. Cost per inquiry dropped because more inquiries were coming from organic search. The developer actually called to ask if we’d done something extra he wasn’t aware of.

Nope. Just this checklist, done properly.

Frequently Asked Questions

What’s the difference between on-page SEO and technical SEO?

On-page SEO is about the content and HTML on each page—your titles, headers, keywords, internal links. Technical SEO is about your site infrastructure—crawlability, site speed, mobile-friendliness, indexing. There’s overlap (page speed touches both), but on-page is more content-focused.

How long does it take to see results from on-page SEO?

Honestly? Anywhere from two weeks to six months, depending on your starting point and competition. We usually see some movement within 4-8 weeks. Big improvements might take three to four months. If someone promises results in one week, they’re either lying or doing something risky.

Can I do on-page SEO myself or do I need an agency?

You can definitely do the basics yourself. Title tags, meta descriptions, headers, alt text—none of that requires technical expertise. The tricky parts are knowing which keywords to target, understanding search intent, and diagnosing technical issues. That’s where experience helps. If you’re a small business with time to learn, start yourself. If you’d rather focus on running your business, hire someone who does this daily.

Is on-page SEO enough or do I need off-page SEO too?

You need both, but on-page comes first. Think of it this way: off-page SEO (backlinks, citations, social signals) is about building your reputation. On-page SEO is about making sure people and Google can understand and use your site when they get there. Perfect on-page won’t rank you for competitive keywords without any backlinks, but great backlinks won’t help if your pages are a mess.

How do I know if my on-page SEO is working?

Track these metrics in Google Analytics 4 and Google Search Console: organic traffic, rankings for target keywords, click-through rates from search results, bounce rate, time on page, conversions from organic traffic. If you’re doing on-page right, you should see traffic and rankings improve over a few months. We usually give it 60-90 days before making judgments.

Should every page target a different keyword?

Yes. Each page should have a clear primary keyword or topic. Otherwise you end up competing with yourself—multiple pages targeting the same keyword, splitting your ranking potential. Map out one primary keyword per page. Related keywords and variations can appear on the same page, but each page needs its own focus.
