SEO optimisation is the process of improving your website to increase its visibility in search engine results for relevant queries. It encompasses technical improvements like site speed and mobile responsiveness, on-page elements such as content quality and meta tags, and off-page factors including backlinks and brand mentions. The optimisation process involves analysing how search engines crawl and index your site, identifying weaknesses or opportunities, then implementing strategic changes to improve rankings. Effective SEO optimisation requires ongoing effort as search algorithms evolve, competitor landscapes shift, and user behaviour changes. It's not a one-time fix but rather a continuous process of refinement and improvement.
