SEO is crucial because it helps websites appear higher in search engine rankings, leading to increased visibility, more organic traffic, and potential conversions. It improves the user experience, credibility, and trustworthiness of a website, making it essential for online success.

The timeframe for seeing results from SEO can vary depending on various factors such as the competitiveness of keywords, the website's current state, the quality of optimization efforts, and search engine algorithms. Generally, it can take several weeks to months before noticeable improvements in rankings and organic traffic are observed.

Yes, backlinks remain an important factor in SEO. High-quality and relevant backlinks from authoritative websites can boost a website's credibility and authority in the eyes of search engines. However, it's crucial to focus on acquiring natural, organic, and diverse backlinks rather than engaging in manipulative practices that violate search engine guidelines.
