SEO typically takes 3–6 months to show meaningful results for new websites, and 1–3 months for established sites. The timeline depends on your competition, domain authority, content quality, and how consistently you implement optimisation strategies.
Absolutely. AI-powered search (like Google's AI Overviews) actually relies more heavily on well-structured, authoritative content. Websites optimised with strong E-E-A-T signals, structured data, and comprehensive topic coverage are best positioned to appear in AI-generated answers.
On-page SEO refers to optimisations you make directly on your website — content, meta tags, page structure, internal links. Off-page SEO refers to external signals like backlinks, brand mentions, and social signals that indicate your site's authority and reputation.
Not necessarily. Many businesses successfully manage SEO in-house, especially with resources like SEOSource. For complex, high-competition markets or large sites, agencies can accelerate results — but understanding SEO yourself is valuable regardless, so you can evaluate and guide any agency you work with.
