The three get used almost interchangeably in casual conversation, and picking the wrong one for the problem wastes both time and budget. Here's the actual division of labour.
Public relations
PR builds visibility and narrative proactively — media placements, thought leadership, announcement strategy. It's built to create coverage, not to address existing coverage that's already working against you. A PR agency asked to "fix" a negative search result is usually operating outside its core skill set, even where the individual practitioners are genuinely good.
SEO
SEO improves how content ranks — technical optimisation, keyword strategy, link building. Standard SEO practice is built for products, services and brand visibility in commercial search terms. Applying it to a person's name carries different risk: the techniques that work for ranking a product page can look manipulative when applied to displacing a negative result about a named individual, and generic SEO agencies frequently don't understand the legal options that should be tried first.
Reputation management
This is the discipline built specifically for existing negative material: assessing whether it can be removed, de-indexed, displaced or corrected, using the legal routes available (POHA, defamation, platform policy, data protection requests) alongside the search-engineering techniques SEO also uses. It requires both legal literacy and search skill, applied to the specific, often urgent problem of an existing result rather than to building visibility from a neutral starting point.
| Best for | Not built for | |
|---|---|---|
| PR | Building visibility, launches, thought leadership | Addressing existing negative coverage |
| SEO | Commercial ranking, product/service visibility | Legal removal routes; risk judgment on personal-name content |
| Reputation management | Existing negative material — repair, protection, crisis | Building a proactive media presence from zero |
Where they overlap and work together
Reputation management and PR intersect at the correction stage — getting a publisher to update a story, or generating genuine positive coverage as part of displacement, both draw on media relationships. Reputation management and SEO intersect on the technical side of holding a displaced position. Neither overlap means the disciplines are interchangeable.
The fastest way to waste a reputation budget is spending it with an agency whose actual core skill is adjacent to the problem, not built for it.
How to tell which you need
If nothing negative exists and the goal is visibility: PR. If the goal is ranking for commercial terms with no personal-name sensitivity: SEO. If there's an existing negative result, a live crisis, or a compliance-relevant search problem: reputation management, and specifically an agency where that's the core practice rather than an add-on service.
