What Agency SEO Work Actually Involves
Most people outside the industry think SEO means "putting keywords on a website." Even some hiring managers at agencies don't fully grasp what their SEO team does between 9 and 5. If you're considering a move into agency-side SEO, you deserve a straight answer about what the job looks like week to week.
The short version: agency SEO is part technical consultant, part data analyst, part client relationship manager, part content strategist. The long version is what follows.
A Typical Week in Agency SEO
Monday morning usually starts with a scan of rankings and traffic data across your client portfolio. Most agency SEOs manage between four and eight accounts at any time, depending on retainer size and seniority. You're checking for sudden drops, algorithm updates, or ranking gains that need flagging.
By mid-morning, you're probably in a client call. These range from quick 15-minute check-ins to hour-long strategy sessions. Agencies bill by the hour or by retainer, so there's always pressure to show progress. You need to explain technical concepts to marketing managers who may have limited SEO knowledge.
Afternoons tend to be the doing time. That might mean running a technical audit on a client's site, building a keyword map for a new content campaign, analysing backlink profiles, or writing optimisation briefs for the content team. You'll rarely do the same thing two days running.
Fridays often involve reporting. Monthly reports are a constant in agency life. You're pulling data from Google Search Console, Google Analytics, Ahrefs or SEMrush, and sometimes bespoke dashboards. The skill isn't pulling the data. It's telling a story with it that justifies the client's spend.
The Tools You'll Use Every Day
Your agency will have its preferred stack, but expect to use some combination of these on a daily basis.
Google Search Console and Google Analytics 4 are non-negotiable. Every client has them. You'll spend more time in Search Console than you'd expect, diagnosing indexing issues and tracking impression trends.
For keyword research and competitive analysis, most agencies use Ahrefs, SEMrush, or both. Ahrefs tends to be favoured in the UK agency world, though SEMrush has closed the gap. Budget-conscious agencies sometimes rely on free tools like Ubersuggest, but this limits what you can deliver.
Screaming Frog is the standard for technical audits. You'll crawl client sites regularly to catch broken links, redirect chains, duplicate content, and indexation problems. Learning to configure custom crawls will save you hours each month.
For local SEO accounts, you'll likely use BrightLocal or Whitespark. For link building, tools like Pitchbox or BuzzStream help manage outreach at scale. Looker Studio (formerly Google Data Studio) handles reporting dashboards.
One thing agency SEOs learn fast: the tool doesn't do the thinking. Knowing which tabs to ignore in Ahrefs matters as much as knowing which ones to use.
Client Management: The Part Nobody Warns You About
Here's the honest bit that most job adverts skip. A significant chunk of agency SEO work is managing people, not managing websites.
You'll deal with clients who want to rank number one for a head term within a month. Clients who ignore your recommendations and then ask why traffic hasn't improved. Clients who read a blog post about AI and want to know why you're not using it to triple their rankings overnight.
The best agency SEOs learn to set expectations early and communicate progress clearly. A 2023 survey by BrightLocal found that 56% of agencies cited "client education" as one of their biggest challenges. That tracks with our experience.
You'll also navigate internal politics at the client's end. Their developer team may push back on your technical recommendations. Their content team might rewrite your carefully optimised copy. Their CEO might demand you focus on vanity keywords that won't drive revenue.
This is where agency SEO differs most from in-house work. In-house, you can walk down the corridor and talk to the developer. In an agency, you send a recommendations document and hope someone implements it before the next quarterly review.
Agency SEO vs In-House SEO
The biggest difference is variety. In an agency, you'll work across multiple industries, site architectures, and business models. You might optimise an e-commerce site selling garden furniture in the morning and audit a SaaS platform's technical setup after lunch. This breadth of experience is one of the strongest reasons to start your SEO career agency-side.
In-house SEO roles offer depth instead. You get to see the long-term impact of your strategies, own the full roadmap, and work closely with product and development teams. According to Moz's 2023 Industry Survey, in-house SEOs reported higher job satisfaction on average, largely because they had more control over implementation.
Agency roles tend to pay slightly less at junior levels but catch up at senior level, where the management and commercial skills you develop become genuinely valuable. A mid-level agency SEO in London earns between £35,000 and £50,000 based on 2024 Glassdoor data. In-house equivalents at larger companies can push into the £50,000 to £65,000 range.
The pace is different too. Agency life moves fast. You'll juggle deadlines, client calls, and new business pitches. Some people thrive on that energy. Others burn out within two years.
Agency SEO vs Freelance SEO
Freelancing appeals to experienced agency SEOs who want more control over their schedule and client base. The trade-off is clear: higher earning potential per hour, but no steady income, no team to lean on, and you handle your own sales, invoicing, and admin.
Most successful freelance SEOs spent at least three to five years in an agency before going independent. The agency years give you the systems, processes, and client management skills that freelancing demands from day one.
If you're early in your career, agency work is the better training ground. You'll learn faster surrounded by senior SEOs, PPC specialists, content strategists, and developers than you will working alone from a spare bedroom.
Reporting and Proving Your Value
Reporting is where many agency SEOs struggle. Not because the data is hard to pull, but because the interpretation matters more than the numbers themselves.
A good agency SEO report doesn't just show that organic traffic went up 12% month on month. It connects that increase to specific actions: the technical fixes that improved crawlability, the content that started ranking, the links that boosted authority. And it ties those improvements to business outcomes like leads, revenue, or phone calls.
Most agencies report monthly, with quarterly strategy reviews. Some clients want weekly updates. The format varies between Looker Studio dashboards, PowerPoint decks, and PDF reports. What matters is that you can explain what happened, why it happened, and what you're doing next.
Expect to spend roughly 15-20% of your billable time on reporting. It's not glamorous work, but it's what keeps clients paying their retainer.
Career Progression in Agency SEO
A typical agency career path runs something like this:
SEO Executive / Junior SEO (£22,000-£30,000): You'll handle day-to-day tasks like keyword research, content briefs, and basic reporting. Expect a lot of learning and hands-on support from senior team members.
SEO Manager (£30,000-£45,000): You own client relationships and strategy. You're responsible for results and for managing junior team members. This is where client management skills become critical to your progression.
Senior SEO Manager / Head of SEO (£45,000-£65,000): You shape the agency's SEO offering, contribute to new business pitches, and oversee the whole team. At this level, you spend more time on strategy and leadership than hands-on implementation.
SEO Director (£60,000-£85,000+): Typically found at larger agencies. You're accountable for the performance and profitability of the SEO department. Board-level reporting and revenue targets are a regular part of your week.
The jump from executor to manager is the hardest transition. Technical skills alone won't get you promoted. You need to demonstrate commercial awareness, an ability to grow client accounts, and genuine leadership capability.
Skills That Hiring Managers Actually Care About
If you're applying for agency SEO roles, here's what really matters in interviews and on the job.
Technical SEO knowledge is table stakes. You need to understand crawling, indexing, site speed, structured data, and Core Web Vitals. You don't need to be a developer, but you need to speak their language well enough to write clear implementation briefs.
Communication skills separate good agency SEOs from great ones. You'll present to clients, write proposals, and explain complex concepts in plain language multiple times a week. If you can't do that confidently, agency life will be rough.
Commercial awareness matters more than most SEOs realise. Understanding how your work connects to the client's revenue, and being able to articulate that connection, is what gets retainers renewed.
Curiosity is underrated. Google makes thousands of algorithm changes per year. The SEOs who keep up with those changes, test hypotheses, and adapt their approach are the ones who build lasting careers.
Is Agency SEO Right for You?
Agency SEO suits people who like variety, can handle pressure, and enjoy working with different people and businesses. If you prefer going deep on a single brand and owning every decision end to end, you'll probably be happier in-house.
The agency path is particularly strong for the first three to five years of an SEO career. The range of clients, challenges, and colleagues you'll encounter accelerates your development in a way that other environments can't match.
If you're ready to start looking, browse current SEO jobs at digital agencies on our board. We list roles from junior positions through to director-level, across agencies of all sizes throughout the UK.
And if you're already in agency SEO and thinking about your next move, consider what skills you're building right now. The reporting, the client calls, the stakeholder management, the cross-team work: it all compounds. Two years of solid agency SEO experience is worth five years in most other marketing roles. That's not hype. Ask anyone who's hired for a senior in-house position what kind of candidates they prefer.
