SEO (Search Engine Optimisation) doesn’t have to be complicated. Yes, there are hundreds of factors that Google considers when ranking content, but you don’t need to master them all overnight. By focusing on a few key areas, you can make a big impact in a short amount of time.

In this post, I’m sharing three quick SEO fixes that you can implement today to strengthen your blog’s visibility, improve accessibility, and give search engines (and your readers) exactly what they need.

1. Optimise Your Heading Structure for Search Engines

Have you ever noticed how WordPress defaults to H2 when you add a new header block? That’s not random – headings give search engines vital clues about your content’s structure and relevance.

Best practice:

  • Only one H1 per page (your blog title).
  • Use H2 for main subtopics, and H3 for supporting points under those.
  • Sprinkle semantic keywords (related terms) into your headers naturally.

For example, if your main keyword is “Writing High Converting Emails” (H1), your H2s might be “How to Increase Open Rates” and “Boosting Click-Through Rates.” Under each, your H3s could explore specifics like “Subject Lines That Work” or “Crafting a Compelling Call to Action.”

💡 BOLD Tip: Use a tool like CoSchedule’s Headline Analyzer to check your titles. For WordPress users, double-check that your theme applies the H1 tag to blog titles only (and not elsewhere on the page).

2. Add Alt Tags to Every Image

Alt text is one of the easiest SEO wins – yet it’s often ignored.

The alt attribute serves two important purposes:

  1. Accessibility: Screen readers use it to describe images to visually impaired visitors.
  2. SEO: Search engines read alt text to better understand your content.

How to write strong alt text:

  • Describe the image clearly.
  • Include your target keyword if it’s relevant.
  • Avoid keyword stuffing or vague text like “image123.jpg.”

👉 Example: Instead of “Blog graphic,” write: “Pinterest Pin graphic for blog post on writing emails that convert.”WordPress Tip: When uploading to the media library, fill in the “Alt Text” field on the right-hand side. If you’ve already uploaded lots of images without alt text, plugins like Rank Math can dynamically generate them for you.

Adding the Alt Text in WordPress

In the example above, the alt tag is “Pinterest Image for the blog post How To Write Emails That Convert” This explains the purpose of the image and also includes the same keywords used in the blog title.

If you can’t include keywords in an alt tag for some reason (such as the image being purely decorative), at least provide a clear description of the image, so that it meets accessibility guidelines and aids your visually impaired users.

If you have hundreds of images scattered throughout your site without alt tags, consider using a plugin such as Rank Math to add missing alt tags to your images dynamically.

3. Strengthen Internal Linking

Getting backlinks from other websites is powerful, but internal links are something you control completely – and they’re just as important.

Why internal links matter:

  • Help Google understand your site’s structure.
  • Spread link equity (ranking power) across your pages.
  • Keep readers engaged by guiding them to related posts.

Best practices:

  • Link older posts to newer ones when relevant.
  • Update older posts regularly to check for broken or outdated links.
  • Use descriptive anchor text (e.g., “learn more about email marketing tools” instead of “click here”).

💡 BOLD Tip: Add a monthly or quarterly content audit to your calendar. A quick review ensures your internal linking stays strong, and your older content continues to support your newer posts.

More SEO Tips

  • Use a tool like Headline Analyzer to check your blog titles are optimised.
  • Use a plugin such as Rank Math to dynamically add an alt tag where they are missing.
  • Schedule an annual content audit. For each blog post (particularly older ones) check that:
    • content is still relevant and correct
    • all internal links still work and update where necessary
    • older posts contain links to any new content written since
    • all external backlinks are still correct and update where necessary

You don’t need to overhaul your entire site in one day. By optimising your headings, adding descriptive alt tags, and strengthening your internal linking, you’ll make your site more user-friendly and SEO-friendly at the same time.
