What is SEO?
SEO (Search Engine Optimisation) is the process of improving your website to rank higher in organic search results on Google and other search engines. It involves technical improvements to your site structure, creating high-quality content that answers what people are searching for, and building authoritative backlinks from other websites. Unlike paid advertising, SEO delivers long-term, compounding results - the work you invest today continues to drive traffic for months and years to come.
Why Hire a SEO Agency?
- Expert knowledge of Google algorithm updates and ranking factors
- Access to professional SEO tools worth thousands per year
- Technical audits that identify issues you would never find yourself
- Content strategies based on real keyword research and search intent data
- Link building campaigns that build genuine authority
- Regular reporting on rankings, traffic and conversions
Frequently Asked Questions
How much does an SEO agency cost in the UK?
UK SEO agency costs typically range from £400-£1,000/month for local SEO, £1,000-£3,000/month for national campaigns, and £3,000-£10,000+ for enterprise or highly competitive sectors. Be cautious of agencies charging under £300/month as effective SEO requires significant research, content production and technical work.
How long does SEO take to show results?
Most SEO campaigns take 3-6 months to show meaningful results, though some improvements can appear sooner. SEO is a long-term investment - the agencies that promise instant results are usually cutting corners. Expect to see steady improvement over 6-12 months with a good agency.
What should I look for in an SEO agency?
Look for case studies with measurable results, transparency about their methods, regular reporting, and no guarantees of specific rankings (no one can guarantee that). A good SEO agency will ask detailed questions about your business goals before proposing a strategy.
Is SEO better than PPC for my business?
SEO and PPC serve different purposes. SEO delivers sustainable, long-term traffic growth at a lower cost per click over time. PPC delivers immediate results but stops when you stop paying. Most successful businesses use both. SEO is typically better for businesses with longer buying cycles and those building brand authority.
