On-page SEO for Google Sites:

• Optimize your titles and headings: Include relevant keywords in your website title, H1 (main heading), and H2 subheadings. This helps search engines understand your content and users skim your page for the information they need.

• Target the right keywords: Conduct keyword research to identify terms people use to search for businesses or information like yours. Use those keywords throughout your website content, but naturally, not forced.

• Write high-quality content: Google prioritizes informative, fresh, and valuable content. Regularly update your site with new content relevant to your target audience.

• Optimize images: Include alt text descriptions for your images that include relevant keywords. This helps search engines understand the content of your images and also improves accessibility for visually impaired users.

• Internal linking: Link to relevant pages within your Google Sites. This helps search engines understand the structure of your website and improves user navigation.

Technical SEO for Google Sites:

• Mobile-friendliness: Ensure your Google Site is responsive and displays well on all devices, especially smartphones and tablets. Google prioritizes mobile-friendly websites in search results.

• Site speed: A slow loading website can hurt your search ranking. Use tools like Google PageSpeed Insights to test your website speed and identify areas for improvement.

• Security: Make sure your Google Site uses HTTPS encryption. This shows Google and visitors that your site is secure.

Additional tips:

• Promote your Google Site: Share your website on social media, online directories, and relevant forums. This can help build backlinks to your site, which is a ranking factor for Google.

• Use Google Search Console: This free tool from Google allows you to monitor your website's search traffic and identify areas for improvement. You can also submit your sitemap to Google Search Console to help Google index your pages.

Keep in mind:

SEO is an ongoing process. It takes time and consistent effort to see results.

Focus on creating a high-quality website with valuable content for your target audience. Google rewards websites that provide a good user experience.
