Hello! Welcome back to our module on Search Engine Optimization.
In our last lesson, you learned how to find low-competition, long-tail keywords. This is a crucial first step because it gives you a clear topic that people are actively searching for. Now that you have a target keyword, the next logical question is: "What do I do with it?"
This lesson answers that question. Our goal is to identify the key on-page SEO elements: title tag, meta description, headings, and URL structure. These are the fundamental building blocks you will use to construct a blog post that is optimized for both search engines and human readers. Mastering these elements will help Google understand what your content is about and persuade users that your page has the answer they need.
An Overview of On-Page SEO Elements
On-page SEO refers to all the optimizations you do on your actual website pages. The elements we're covering today are some of the most important ones. This image provides a great high-level map of where today's topics fit into the bigger picture.
As you can see, these elements are core to optimizing your content. Let's break them down one by one.
1. The Title Tag: Your Page's First Impression
The first, and arguably most important, element is the title tag. This is an HTML element that specifies the title of a web page. It serves two critical functions:
- It tells search engines the main topic of your page. It is a very strong signal for rankings.
- It appears as the clickable blue link in Google search results. A compelling title tag encourages users to click on your result over your competitors'.
To get a clear understanding of what a title tag is and how to craft an effective one, please watch this segment from a Semrush video.
What Is On-Page SEO? Everything You Need to Know In 2025
This video, 'What Is On-Page SEO?', clearly explains the role of the title tag, where to find it in the page's code (don't worry, you won't need to code!), and best practices for creating one.
Watch the segment from 03:57 to 05:42. Focus on the recommendations for character length and keyword placement.
As the video explained, the title tag is your page's headline on Google. For a deeper dive, the Moz "Beginner's Guide to SEO" provides an excellent text summary.

This section from Moz's guide, titled 'Title tags', reinforces what you just learned and shows where else title tags appear, like in browser tabs and on social media.
Read the section 'Title tags'. Pay attention to the three places a title tag is displayed, as shown in the images.
Key Takeaways for Title Tags:
- Length: Keep it under 60 characters to avoid it being cut off in search results.
- Keyword: Include your primary target keyword, preferably near the beginning.
- Compelling Copy: Make it interesting and clickable. Ask a question or highlight a key benefit (e.g., "Best Coffee Grinder for French Press in 2024").
- Uniqueness: Every page on your site must have a unique title tag.
2. The Meta Description: Your Ad on Google
Right below your title tag in the search results is the meta description. This is a short snippet of text that summarizes the page's content.
While Google has stated that meta descriptions are not a direct ranking factor, they are incredibly important. A well-written meta description acts like ad copy, convincing the searcher to click on your link. A higher click-through rate (CTR) can indirectly signal to Google that your page is a good result, which can positively influence rankings over time.
Let's return to the Semrush video for a concise explanation.

This next segment explains the meta description's function, why it's still important even though Google sometimes rewrites it, and what to avoid when writing one.
Watch from 05:42 to 07:07. Notice the advice on being descriptive and trustworthy, not 'spammy'.
Key Takeaways for Meta Descriptions:
- Length: Aim for under 160 characters.
- Keyword: Include your target keyword naturally. Google often bolds the search term in the description, which helps it stand out.
- Sell the Click: Clearly state what the user will find on the page and why it's valuable. What problem does it solve?
- Be Honest: The description must accurately reflect the content on the page to build trust.
3. The URL Structure: A Clear Path for Users and Bots
The URL (Uniform Resource Locator) is the web address of your page. A clean, descriptive URL helps both users and search engines understand what the page is about before they even get there. The part of the URL you can control for each post is often called the "slug."
- Bad URL:
yourwebsite.com/p?id=123 - Good URL:
yourwebsite.com/blog/best-running-shoes
This short clip explains the concept very clearly.

The Semrush video also provides a quick, effective explanation of how to structure your URL slug.
Watch from 07:07 to 08:03. The video gives excellent examples of good and bad URL structures.
For a more comprehensive look at all the best practices for URLs, the Moz guide is an excellent resource.

To understand all the nuances of creating great URLs, please read this section from the Moz guide.
Read the entire section titled 'URL structure: Naming and organizing your pages'. Focus on the advice regarding length, keyword usage, and using hyphens for word separation.
Key Takeaways for URL Structure:
- Clarity: Make it short, descriptive, and easy to read.
- Keyword: Include your target keyword.
- Formatting: Use hyphens (
-) to separate words. Don't use spaces, underscores, or other characters. - Evergreen: Avoid putting dates in URLs for content that won't go out of date (e.g., reviews, how-to guides).
4. Headings: Structuring Your Content for Readability
Once a user clicks through to your page, you need to present your content in a clear, easy-to-read format. Headings (H1, H2, H3, etc.) are essential for this. They create a logical structure for your article, much like an outline in a book.
- H1 Tag: This is the main title of your article as it appears on the page. There should only be one H1 tag per page. It should contain your target keyword and is often very similar to your title tag.
- H2 Tags: These are the main subheadings of your article. They break the content into logical sections.
- H3-H6 Tags: These are sub-subheadings used for further organization within H2 sections.
Headings help users scan your content to find what they need, and they help search engines understand the structure and topics covered in your article.

Let's turn back to the Moz guide for a clear explanation of how heading tags work to create a content hierarchy.
Read the section titled 'Header tags'. The example of the Copenhagen tour page clearly illustrates the H1 -> H2 -> H3 structure.
The Semrush video also shows a great practical example of how headings are used within an article.

This final clip from the Semrush video will show you how these heading tags look on a live web page.
Watch from 07:51 to 09:00. The presenter shows how to find the H1 and H2 tags in a real Investopedia article.
Key Takeaways for Headings:
- Hierarchy: Use one H1 for your main title. Use H2s for main sections, and H3s for sub-points within those sections.
- H1 Keyword: Your H1 tag must include your primary target keyword.
- Readability: Use headings to break up long blocks of text and make your content easy to scan.
- Secondary Keywords: Subheadings (H2, H3) are a great place to use related or secondary keywords you found during your research.
Putting It All Together
You've now learned about the four key places to signal your page's topic. This checklist provides a great visual summary of how these elements come together when you're optimizing a post.
To connect this directly to your work, remember the 'focus keyword' you researched in the last lesson. The goal is to naturally weave this keyword into each of the elements we discussed today.
The practical guide to on-page SEO for beginners
This guide from Mangools does a great job of explaining how to use a 'focus keyword' across all the important on-page elements without overdoing it.
Please read the section titled 'Optimize for the focus keyword'. This will tie together everything we've learned and reinforce the importance of writing naturally.
Conclusion
Great work! You now know the fundamental on-page SEO elements and where to place your keyword to give your content the best chance of ranking.
Key Takeaways:
- Title Tag: The clickable headline in search results. It's a key ranking factor and drives clicks.
- Meta Description: The ad copy under your title. It sells the click by explaining the page's value.
- URL Structure: The web address. It should be short, clean, and contain your keyword.
- Headings (H1, H2s): The on-page outline. They structure your content for users and search engines. Your H1 is your on-page title.
