The Only On-Page SEO Checklist You Need in 2025

1. SSL Certificate – Secure Your Site

When your website URL starts with https:// (not http://), it means it’s secure. This protects your visitors’ data and builds trust. Google also prefers secure sites, so make sure your hosting provider gives you an SSL certificate—most offer it for free.

 

• Tip: If your site shows “Not Secure” in the browser, you need to activate SSL.

2. WWW Redirection – Choose One Version of Your Site

Did you know that you can access your website as www.yourwebsite.com or just yourwebsite.com. Both are fine, but Google sees them as two different versions unless you pick one and redirect the other.

 

• Tip: Decide on your preferred version and ask your developer (or set it in hosting) to redirect traffic properly.

3. Page Speed – Make It Load Faster

 

Nobody likes a slow website. Do you ever wait for a page load more than 3 seconds before getting frustrated and clicking back. Tools like Google PageSpeed Insights help you see what’s slowing things down—usually large images, bad hosting, or too many plugins.

 

• Tip: Compress images and remove unnecessary plugins to speed up your site.

 

4. Mobile Friendliness – Be Great on Phones

Most people browse on their phones. Your website should work perfectly on small screens. It should not be an afterthought. In 2025 google actually gives more priority to Mobile than desktop. Use Google’s Mobile-Friendly Test to check.

 

• Tip: Use a responsive theme if you’re on WordPress or any website builder.

 

5. Clean URL Structure – Keep It Simple

 

Instead of long, confusing URLs like:

example.com/page?id=483

Use:
example.com/seo-checklist

Keep your URLs short and descriptive, so both visitors and search engines can easily understand what the page is about.

 

6. Fix Broken Links – Avoid Sending Users to Dead Ends

Broken links not only annoy visitors but also negatively impact your SEO. These are links that lead to pages that no longer exist or show a 404 error.

 

• Tip: Best tools for checking broken links are Broken Link Checker (plugin) or Screaming Frog to find and fix them.

7. Image Optimization – Make Images Light & Meaningful

Big images can slow down your site. Also, Google can’t “see” your images unless you use proper alt text to describe them.

 

• Tip: Use tools like TinyPNG to compress images and always add descriptive alt text like “digital marketing consultant in Kochi.”

8. Content Optimization – Make It Useful & Readable

 

Write content that answers your audience’s questions. Use your target keywords naturally. Break up long paragraphs, add headings, bullet points, and always write for humans—not just search engines.

 

• Tip: Use free tools like Hemingway or Grammarly to improve readability.

9. Header Tags (H1, H2, H3…) – Structure Your website Content as best as possible

Think of header tags like the headings and subheadings in a book—they help organize your content clearly.

 

• Use H1 for the main title of your page, and make sure to use it only once
• H2 for subheadings
• H3 for points under H2

This makes it easier for Google to understand what your content is about and how it’s structured.

 

10. Meta Title & Description – Your First Impression in Google

Meta title and meta description are the ones that you see in a search result for each links.

 

• It is best that the meta title should include your keyword and be 55–60 characters.

• It is best that the meta description should explain what the page is about (up to 155 characters).

• Tip: Write it like a mini-ad that makes people want to click

11. OG Tags – Control How Your Links Look on Social Media

OG (Open Graph) tags decide what shows up when someone shares your page on Facebook, LinkedIn, etc. You can set the title, image, and description.

 

• Tip: Use plugins like Yoast SEO or Rank Math to easily set OG tags.

 

12. XML Sitemap – The blueprint that Help Google Find Your Pages

An XML sitemap is like a blueprint of all the important pages on your website. It tells Google what to crawl and index.

 

• Tip: Tools like Yoast or Rank Math generate it automatically and you can submit it in Google Search Console.

 

13. Internal Linking – Connect Your Pages

Linking related pages within your site helps users navigate better and boosts SEO by spreading link authority.

 

• Tip: Link to related blogs or service pages using simple, meaningful text—like “SEO services in Kochi”—so readers and search engines know what to expect.

 

14. Canonical Tags – Avoid Duplicate Content

If you have similar pages or products, use canonical tags to tell Google which version to index and rank. Otherwise, Google may get confused.

 

• Tip: SEO plugins usually handle this for you automatically.

 

15. Robots Meta Tag – Tell Google What to Index

These tags let you guide search engines on what to do with a page.
For example:

 

• index, follow means the page can appear in search results, and search engines can explore the links on it.

• noindex, nofollow means the page won’t show up in search results, and search engines won’t follow any links on that page.

• Tip: It is best to use “noindex” for thank-you pages, admin panels, etc.

 

16. robots.txt File – Set Crawl Rules

This file gives Google instructions on which areas of your website it’s allowed to visit and which ones to skip.

It’s like giving directions to a visitor about where they can go.

 

• Tip: Don’t block important folders like /wp-content/ by mistake.

 

17. Domain & Page Authority – Build Trust Over Time

Domain Authority and Page Authority are scores given by top seo tools like Moz that show how trustworthy and genuine your website is, based on content quality and backlinks.

 

• Tip: Focus on getting good backlinks from relevant websites, and keep publishing valuable content.
