I would suggest effective on page SEO and off-page SEO.

On-page SEO
1. Use Short URLs with Keywords.
2. Meta Descriptions Help On-Page SEO.
3. Front-Load Your Keyword In Your Title Tag.
4. Use Your Keyword in H1, H2, or H3 Tags.
5. Use Your Keyword Once In The First 150 Words.
6. Mix Content With Synonyms and LSI Keyword.
7. Improve On-Page SEO via Optimized Images.
8. Be Creative When It Comes To Content.
9. SHOULD Include Crosslinking To Related Content.
10. Speed Matters For On-Page SEO.

Off-Page SEO should include articles and content on reputable and related websites to yours. Also, mentions of your site, partnering with other similar websites. For example as its a driving test related site, you may want to consider posting an article on https://learntodriveschools.com/.
