A Complete On-Page SEO Checklist You Want to Refer!

Strategic Keyword Placement

Against all arguments pointing to the importance of user intent overpowering keywords as an essential on-page SEO, keywords still matter! What matters more is their correct placement.

Start by identifying the right terms for your audience. Then, focus on placement:

• Add keywords naturally in URLs, H1 tags, SEO titles, meta descriptions, image alt text, and the first 100 words of your content.

• Keep the character count for meta titles and descriptions to 50 and 150 (including spaces).

• Keep the URL structure as simple as possible.

Best Tools to Try: Ubersuggest for keyword research + SERPsim for previewing metadata.

Content Creation and Optimisation

Good content isn’t just well-written. It is structured to be found, informative to provide value, and engaging to keep visitors on your site. So, build content that informs, solves, and guides.

Here are a few content optimisation tips for SEO:

• Use schema (structured data) to help Google understand your content better.

• Optimise meta titles/descriptions and follow a clear hierarchy using H2s/H3s.

• Create internal links that feel natural and useful.

• Build topical authority using content clusters and related blog series.

• Optimise for Featured Snippets by directly answering key user questions in concise blocks.

Some of these mentioned tips are also essential tick-offs for the on-page SEO audit checklist.

Internal Linking & Content Silos

When you spend hours building your perfect website, you do not want the pages to disappear amidst all the chaos on the Internet. You want Google to find and understand your pages so your target audience can discover you.

Start the journey with smart internal linking.

• Group related content into silos (or clusters).

• Link from high-authority internal pages to new or underperforming ones.

• Use descriptive, contextual anchor text—not vague phrases like “click here.”

Visual Optimisation

Images aren’t just about aesthetics. They impact performance and visibility. Be creative and thoughtful about whether your website visuals clearly articulate the webpage's context and query intent.

A few pro tips for image optimisation include:

• Use keyword-focused file names before uploading.

• Add clear, accurate alt text that describes the image contextually.

• Compress images to improve load speed without sacrificing quality.

Crawlability & Indexing

Even the best content won’t rank if Google can’t crawl or index it properly. You don't want your pieces to get lost in the noise.

Technical on-page SEO is not something you can take lightly.

Consider the following points as essential elements of your checklist for on-page SEO:

• Submit an updated sitemap to Google Search Console.

• Use canonical tags to prevent duplicate content issues.

• Set up a robots.txt file to guide crawl priorities.

• Keep your website loading time less than 5 seconds.

• Reduce image sizes to make your website load faster.

• Ensure that your website follows a responsive interface - it should be mobile-friendly.
