1. Research your keywords: Before you start writing, research the keywords related to your topic. Use tools such as Google AdWords Keyword Planner, UberSuggest, or SEMrush to find the most relevant and searched-for keywords. Incorporate these keywords into your article, including the title, subheadings, and body.

2. Write quality content: Your article should be informative and engaging to your readers. The content should provide value and solve their problems. Make sure to avoid duplicate content and keyword stuffing as it will harm your SEO.

3. Optimize your Title tag: Use your main keyword in your title and make sure it is within 60 characters. The title tag should be compelling and entice readers to click on your article.

4. Use appropriate meta description: The meta description is a short summary of your article and is displayed under the title tag in search results. Use your keywords and keep it under 155 characters. The meta description should be attractive and encourage readers to click on your article.

5. Use header tags: Use header tags (H1, H2, H3) to break up your article into sections. This makes it easier for readers to scan through your article and adds context to your content for search engines.

6. Use internal links: Link to other relevant articles on your website to create a better user experience and help search engines understand the structure of your website better.

7. Mobile-friendly and fast load times: Ensure that your website is mobile-friendly and loads quickly. Google favors websites that are mobile-friendly and have fast loading times.

Remember to make your article readable, informative and optimized for search engines. By following these tips, you`ll be on your way to achieving a higher search engine ranking and more traffic to your website.
