Ask any SEO agency about their audit process, how they measure success at 3, 6, and 12 months, what link-building methods they use, and who will actually work on your account day to day. Cover strategy, reporting, contract terms, and whether their methods follow Google’s guidelines. A good agency answers all of these clearly, without vague promises or guaranteed rankings.
Key facts
- An SEO agency is a company hired to improve a website's visibility in unpaid (organic) search results on Google and other search engines.
- Google's own documentation states that no one can guarantee a number-one ranking in Google Search.
- Most SEO contracts run between 6 and 12 months because organic search results typically take 3 to 6 months to reflect new work.
- The 80/20 rule in SEO (Pareto Principle) means approximately 80% of a site's organic traffic comes from 20% of its pages or keywords.
- There are five commonly cited red flags when evaluating an SEO agency: guaranteed rankings, vague link-building explanations, no case studies, long lock-in contracts with no exit clause, and no named account contact.
- Local SEO and national e-commerce SEO require different skill sets; an agency's specialisation should match your business type and target market.
The Core Questions to Ask About Strategy and Process
Before any contract is signed, you need to understand exactly how an agency plans to approach your site. Vague answers at this stage are a reliable signal of vague work later. Ask these questions and listen for specificity, not enthusiasm.
- What is your process for an SEO audit in the first 30 days? A good answer names the tools used, the areas covered (technical, content, backlinks), and what output you receive.
- How do you decide which keywords to target? Look for a process that references search volume, competition, and your business goals, not just a list of obvious terms.
- Do you handle technical SEO, content, and link building, or only some of these? Many agencies outsource parts of the work; you need to know which parts and to whom.
- Who will be working on my account day to day? If the answer is vague, or if you cannot get a name, that is a problem worth taking seriously.
- How do you communicate progress, and how often? Monthly reporting is standard; anything less frequent makes it difficult to course-correct.
Web SEM, based in Cape Town, builds its process around plain-english reporting and named account contacts from the first week, because accountability is easier when everyone knows who is responsible for what.
Evaluating Results, Measurement, and Reporting
An agency that cannot explain how it measures success before work begins will struggle to demonstrate it afterwards. The questions below separate agencies that track meaningful outcomes from those that report on activity instead of results.
- What does success look like at 3 months, 6 months, and 12 months? Realistic agencies will describe early technical wins, mid-term ranking movement, and longer-term traffic and conversion growth.
- Which metrics do you report on, and how often? Rankings, organic traffic, click-through rate, and conversions are the core set; be cautious of agencies that lead with vanity metrics like domain authority alone.
- Can you show examples of ranking improvements for clients in a similar industry? Ask for before-and-after data, not just traffic graphs, which can be influenced by many factors outside SEO.
Most SEO contracts run between 6 and 12 months because organic results typically take 3 to 6 months to reflect new work. Any agency promising significant results in 30 days is either working in a very low-competition niche or overstating what is possible.
How to Choose the Best SEO Agency
Choosing the best SEO agency means matching their specialisation to your business type, verifying their track record with real case studies, and confirming they use only white-hat methods. Price alone is not a reliable signal of quality.
Check their specialisation first. A local SEO agency and a national e-commerce SEO agency require different skill sets, different tools, and different approaches to link acquisition. Ask whether they have worked with businesses of your size and in your sector. An agency that has never worked in your industry is not disqualified, but they should be able to explain how they would approach the learning curve.
Verify their track record independently. Ask for case studies that show before-and-after ranking data. Then check Google reviews and third-party directories on your own, without relying on testimonials the agency has curated. Ask how long their average client relationship lasts; longer tenure is a reasonable indicator of consistent results, because clients who are not seeing value tend to leave.
Confirm their methods are safe. Agencies using black-hat tactics can produce short-term ranking gains followed by Google penalties that take months or years to recover from. Ask specifically about their link acquisition process. Any agency that guarantees a number-one ranking on Google is making a promise that Google itself says no one can make.
The 80/20 Rule in SEO and Why It Shapes Good Agency Work
The 80/20 rule in SEO, also called the Pareto Principle, holds that roughly 80% of a site's organic traffic comes from 20% of its pages or keywords. In practice, this means most SEO gains come from improving a small number of high-value pages rather than spreading effort evenly across an entire site.
When evaluating a prospective agency, ask how they identify your highest-priority pages and keywords before work begins. An agency that treats every page equally is likely spreading budget too thin. Ask to see how they plan to prioritise work in the first 90 days, and whether that prioritisation is based on traffic potential, current ranking position, or conversion value. The answer tells you a great deal about how they think.
The five critical questions in marketing planning are also worth raising directly with any agency: Who is your target audience? What problem are you solving for them? How will you reach them? What does success look like and how will you measure it? What is your budget and timeline? A capable SEO agency should be able to answer all five for your specific business before a single piece of work begins.
Red Flags to Watch for in an Agency's Answers
Walk away if an agency guarantees specific rankings, refuses to explain their link-building process, cannot show a single client case study, locks you into a 12-month contract with no performance clause, or cannot name the person who will actually work on your account.
- Guaranteed rankings: Google explicitly states no one can guarantee a top position in its search results. An agency making this promise is either uninformed or misleading you.
- Vague link building: "We build high-quality links" with no further detail is not an answer. Ask which sites they target, how they approach outreach, and whether they use any automated tools.
- No case studies: Legitimate agencies have verifiable results they are willing to share. If every example is anonymised or unavailable, that warrants further scrutiny.
- Long lock-in, no exit clause: A confident agency does not need to trap clients in contracts with no performance-based exit. Twelve months is reasonable; twelve months with no recourse if results do not materialise is not.
- No named contact: If you cannot find out who is doing the work, you cannot hold anyone accountable when something goes wrong.
Local SEO Questions for Cape Town and South African Businesses
If your business serves a local or regional market, the questions above need to be supplemented with location-specific ones. General SEO expertise does not automatically translate into strong local search performance.
- Do you optimise Google Business Profiles, and how do you approach that process?
- How do you build local citations, and which directories do you prioritise for South African businesses?
- Have you worked with businesses in Cape Town or elsewhere in South Africa specifically?
- How do you approach SEO for businesses targeting both English and Afrikaans speakers?
These questions add geographic and linguistic context that a generalist agency may not have considered. Local search signals, including citation consistency, proximity relevance, and language targeting, behave differently in South African markets than in the UK or US. An agency with direct experience in this context will give you more specific answers, not generic ones.
If you are ready to put these questions to a Cape Town-based team, Web SEM is available to answer all of them directly.
