Both approaches have legitimate advantages and significant drawbacks, and the right choice depends on your budget, available time, technical skills, and business goals.

Essential Qualities of a Good Local SEO Agency
Core Competencies for DIY SEO
If you choose the DIY route, you need to develop competencies across several disciplines. Technical SEO requires understanding site architecture, page speed optimisation, mobile responsiveness, and structured data implementation. Content SEO demands the ability to conduct keyword research, write optimised content, and build topical authority. Link building requires outreach skills and relationship building. Local SEO adds another layer with Google Business Profile management, citation building, and review strategy. Mastering all of these areas takes significant time and ongoing education as search algorithms evolve.

Track Record Indicators

Look for detailed case studies showing specific metrics: ranking improvements, traffic growth percentages, and most importantly, increases in leads or revenue. Be wary of agencies that only show vanity metrics like impressions or keyword counts without connecting them to business outcomes. Ask for references from current clients in your industry and verify their claims independently through tools like Ahrefs or SEMrush.
