TL;DR

Hiring an internal SEO specialist is excellent for brand immersion and control, provided the business has the budget to support them with tools and a wider team. However, for most businesses, an SEO agency delivers faster results, lower overheads, and immediate access to a specialist team of experts.

Modern SEO is no longer a single skill set. It has evolved into a system that combines technical optimisation, content strategy, link acquisition, UX design, entity building, and conversion rate optimisation (CRO).

On top of this, Google now evaluates businesses across multiple search surfaces, including Map Packs, organic shopping feeds, rich results, Discover, and AEO (Answer Engine Optimisation) for AI summaries.

The Reality: A single in-house hire, no matter how talented, cannot realistically specialise in all these areas. Effective SEO requires constant collaboration between developers, strategists, writers, and analysts. This is why businesses often plateau when relying on a “unicorn” employee to handle everything.

The Pillars of SEO

To rank today, you need to fire on all cylinders:

Experience: Core Web Vitals, CRO, and site speed.

Technical SEO: Site architecture and crawling.

Content Strategy: LLM-ready content and entity optimization.

Off-Page: Link acquisition and digital PR.

Local: Map Packs and GEO (Generative Engine Optimisation).

These pillars now sit alongside newer requirements like AEO, GEO, structured data, LLM formatting, and Map Pack optimisation, which increases the scope even further.

Hiring In-House – Pros & Cons

For many companies, the appeal of hiring in-house is brand immersion. An internal employee lives and breathes your company culture, understands your product nuances deeply, and is available for instant communication.

However, the barrier to entry is high.

• The Financials: A well-experienced SEO strategist in Australia typically costs A$90,000 to A$125,000+ per year (including superannuation and benefits), based on salary expert data.
• The Hidden Costs: Recruitment fees ($10k+), onboarding time (2-4 months), and essential software stacks (Semrush, Ahrefs, Screaming Frog, etc.) which can easily add $12k+ annually.
• The Speed Bump: Between recruitment, onboarding, and strategy formulation, most companies wait 4 to 6 months before seeing meaningful output from a new hire.

Verdict: In-house works best when you have the budget to build a team, not just hire a person.

Agency Advantage: Instant Scale

Partnering with an SEO Perth agency isn’t just about outsourcing; it’s about accessing a “hive mind” of expertise.

• Immediate Access: You aren’t hiring one person; you get a Technical Lead, a Content Strategist, a Link Builder, and a Developer.
• Future-Proofing: Agencies work across hundreds of sites. While an in-house team focuses on one site, agencies are already adapting to the next Google update, implementing structured data for AEO, and refining strategies for AI search.
• Cost Efficiency: You get a full senior team for often less than the cost of a single mid-level employee’s salary.

When In-House Is the Right Move

We believe in giving credit where it’s due. In-house teams are often the right choice for:

1. Highly Regulated Industries: Where legal compliance requires every word to be vetted internally.
2. Massive Content Operations: Enterprise-level news or media sites publishing 50+ pieces of content daily.
3. Product Integration: Tech companies where SEO needs to be baked into the product code itself.

The Hybrid Model: The Smartest Strategy?

Many of our most successful clients choose a Hybrid Model. In this scenario, the Agency provides the high-level strategy, technical roadmap, and heavy lifting (link building/technical fixes), while an internal marketing coordinator handles day-to-day content uploads and stakeholder communication.

This gives you the speed and expertise of an agency combined with the brand knowledge of an internal staff member. It scales effortlessly and ensures your internal team isn’t bogged down by technical debt.

5 Signs You Need an Agency

If you don’t fit the “Enterprise” criteria above, an agency is likely your best ROI.

1. You need speed: You want results faster than a 6-month hiring/onboarding cycle.
2. You have a technical block: Your traffic has plateaued, and you don’t know why.
3. You need the future: You want specialists who understand AEO, Map Packs, and LLMs.
4. You want value: You cannot justify a $130k salary + $15k tool budget for one person.
5. You need recovery: You have been hit by an algorithm update and need advanced forensics.
