An SEO Specialist is responsible for improving a website's visibility in organic search results, driving qualified traffic that converts into leads and customers. Unlike a content writer who focuses primarily on prose, an SEO Specialist owns the technical health of the site, keyword strategy, link acquisition, and performance measurement. A great hire bridges technical and editorial thinking, can communicate clearly with developers and executives, and treats every ranking change as a hypothesis to investigate.
The best SEO specialists are hypothesis-driven and intellectually honest — they know the discipline involves uncertainty and can distinguish between correlation and causation when explaining ranking changes. Ask candidates to walk through a technical problem they diagnosed and fixed, including what the impact was. Strong candidates can also navigate the politics of SEO: persuading developers to prioritise a crawl fix or convincing a content editor to restructure a page requires communication skills that a spreadsheet of rankings cannot reveal.
SEO-specific communities (Twitter/X, LinkedIn groups, Slack channels like SEOFOMO or Ahrefs Insider) are where practitioners self-identify. Digital agencies are a reliable source of candidates with broad exposure across many sites and verticals. In-house candidates from direct competitors or companies targeting the same search landscape can compress the ramp-up period significantly. Freelance SEOs who want to go in-house are often underlooked but bring excellent self-direction and breadth of project experience.
Ask them to walk through a site they grew organically from scratch or recovered after a traffic drop. Follow with 'How do you decide which technical SEO issues to prioritise when you have a long audit backlog?' to test commercial judgement. Probe their link-building thinking: 'What is your process for acquiring backlinks without paid link schemes?' Finally, ask 'A competitor just overtook us for our top keyword — walk me through your first 48 hours of investigation.' This scenario reveals analytical process under pressure.
Anyone guaranteeing a number-one ranking or a fixed traffic uplift by a date is overselling, since no honest practitioner controls the algorithm. Be cautious with candidates fixated only on keywords and backlinks while ignoring technical health, content quality, or search intent. Watch for people who talk in tactics but cannot connect their work to business outcomes like revenue or qualified leads. Reliance on outdated or grey-hat methods, such as buying links or keyword stuffing, is a genuine risk in this field. If they cannot read a Search Console report and explain what they would investigate, the depth may be thin. Finally, dismissiveness about how AI-driven search is reshaping discovery suggests a specialist stuck in an older playbook.
Test breadth and depth, because SEO spans technical, content, and off-page work that rarely live in one person equally. Start with a screen on how they diagnose a traffic drop, which quickly reveals systematic thinking. Add a practical audit exercise on a real or sample site, asking them to prioritise findings by impact, not just list problems. Include a content-strategy discussion to check they understand search intent and topical authority, not only mechanics. A technical round should probe crawlability, indexation, and Core Web Vitals with genuine understanding. Finish with a stakeholder conversation, since much of SEO is persuading developers and writers to act on recommendations they did not request. Score against measurable impact and current, ethical methods.
