What Does an SEO Agency Actually Do? From Technical SEO to Content and Reporting

SEO is a process of improving how customers discover and understand a business

Many businesses know they need SEO, but the work behind the term can be difficult to evaluate. One agency may talk mainly about keywords and backlinks. Another may start with technical checks, page structure, content and conversion paths.

A useful SEO programme connects these activities to the way customers search and the way the business sells. It should improve the website's ability to be discovered, understood and used, while giving the business a clear view of what work has been completed.

This guide explains the main responsibilities of an SEO agency and what a business should expect from the process.

1. Discovery: understand the business before choosing keywords

SEO should begin with context. The agency needs to understand the business model, services, target customers, locations, margins, sales cycle and the type of enquiry that matters.

A company selling a specialist industrial service may need a different search strategy from a retailer with hundreds of products. A local service provider may depend on location-based searches, while a national B2B company may need educational content for longer buying journeys.

Discovery should also identify which pages already generate enquiries, which services are priorities and what differentiates the business. Without this context, keyword research can become a list of phrases that attract visitors but do not fit the commercial objective.

2. Technical SEO: make the website accessible and understandable

Technical SEO reviews the foundations that affect crawling, indexing and page experience. Depending on the website, this may include:

• Checking whether important pages can be crawled and indexed.
• Reviewing robots directives and XML sitemaps.
• Checking canonical URLs and redirect behaviour.
• Finding broken pages, redirect chains and duplicate URLs.
• Reviewing page titles, meta descriptions and heading structure.
• Checking mobile usability and page performance.
• Reviewing internal links and navigation.
• Checking structured data where it accurately describes the page.

Not every website needs a major technical rebuild. The agency should prioritise issues according to their impact and explain which items are urgent, which are improvements and which are not relevant to the current site.

Technical changes should be tested. A canonical correction, redirect or indexing change can affect which URL search engines treat as the main page, so changes should not be made casually.

3. Keyword research: understand search intent

Keyword research is not just finding phrases with high search volume. It is understanding what a person wants when they type a query.

Some searches indicate that a visitor is learning about a topic. Others suggest that they are comparing providers, checking prices or ready to make an enquiry. Those different intentions should lead to different page types.

An SEO agency should group related keywords by intent and map them to relevant pages. A service page may target commercial phrases, while a blog article answers a specific educational question. If several pages target the same intent without a clear distinction, they may compete with each other or confuse visitors.

Search volume and keyword difficulty are estimates, not guarantees. The agency should also consider relevance, location, competition, business value and whether the website can realistically provide a better answer than existing results.

4. On-page SEO: improve the pages that matter

On-page work helps visitors and search engines understand the purpose of each page. It may include:

Page titles and descriptions. Write unique, accurate titles and meta descriptions that explain the page. They should not be stuffed with variations of the same keyword.

Headings and structure. Organise the content with clear headings so readers can scan the page and understand how sections relate.

Content quality. Explain the service, process, use cases, limitations and questions customers commonly ask. Avoid generic paragraphs that could describe any business.

Internal links. Connect related pages using descriptive anchor text. A blog article should guide readers to the relevant service page when it makes sense.

Images. Use relevant visuals with appropriate file sizes and descriptive alt text when the image communicates information. Alt text should describe the image, not act as a keyword list.

Google's guidance recommends useful content, clear organisation and crawlable links. Read the Google SEO Starter Guide.

5. Content strategy: answer questions that influence decisions

Content should support real customer questions. A business may need articles that explain how a service works, compare approaches, clarify cost factors, identify common mistakes or help readers prepare for a project.

The strongest topics are connected to the services the company actually delivers. An article should add useful detail and guide the reader to the next relevant resource. Writing about unrelated trending topics simply because they have search volume may bring traffic without building authority in the company's market.

A content plan should define the target reader, search intent, primary page, supporting keywords, internal links and the unique information the article will provide. Existing articles should be reviewed and updated when the underlying information changes.

6. Authority and links: build credibility carefully

Links from relevant websites can help people discover a business and provide context about its reputation. However, link building should focus on legitimate relationships, useful resources, industry participation, digital PR and content worth referencing.

Be cautious of packages that promise hundreds of backlinks at a very low price or use networks of unrelated sites. A report showing a large backlink count does not prove that those links are useful or safe.

Ask an agency to explain the source, relevance and purpose of any link acquisition work. Avoid tactics that depend on manipulating link signals rather than earning meaningful references.

7. Local SEO: help nearby customers find the business

For businesses serving defined locations, local SEO can involve accurate business details, a properly managed Google Business Profile, relevant local pages, reviews and consistent information across the web.

Google says local results are mainly based on relevance, distance and prominence. There is no way to request or pay Google for a better local ranking. Businesses can improve the accuracy and completeness of their profile, but they cannot control a searcher's distance or guarantee the outcome. See Google's local ranking guidance.

Local pages should contain useful location-specific information. Creating many near-identical pages that only swap the city name does not create a genuine local resource.

8. Measurement: report work and business outcomes

SEO reporting should connect activity to results. Depending on the project, useful measures may include:

• Organic clicks and impressions.
• Queries and landing pages gaining visibility.
• Rankings for selected target keywords.
• Technical issues fixed and pages indexed.
• Organic enquiries, calls or transactions where tracking is configured.
• Content published or refreshed.
• Conversion rate and lead quality.

A ranking report alone is not enough. Rankings can vary by location, device and search context. Traffic also has limited value if it does not reach relevant pages or produce useful business outcomes.

A good report explains what changed, what the data suggests, what remains uncertain and what work is planned next.

9. What should a monthly SEO engagement look like?

The exact scope depends on the website and programme. A smaller campaign may focus on technical fixes, page optimisation and a limited content plan. A larger campaign may include multiple service pages, product optimisation, location strategy, digital PR and more detailed reporting.

The agency should define deliverables clearly: which pages will be worked on, how many pieces of content are planned, which technical tasks are included, how keywords are tracked and when performance is reviewed.

SEO is not a one-time switch that guarantees a fixed position. Competition, site changes, content quality, demand and search systems all influence results. Be cautious of guarantees such as “number one on Google” or fixed results within a few days.

10. Questions to ask before hiring an SEO agency

1. How will you understand our business and target customers?
2. How do you group keywords by search intent and map them to pages?
3. What technical checks will you perform first?
4. What content will you create or improve, and who approves it?
5. How do you approach links and local SEO?
6. What will the monthly report show?
7. Which tasks are included and which are quoted separately?
8. How do you handle changes to search traffic or ranking performance?

The answers should be specific to the business, not a copy of a generic package description.

Final thoughts: look for a process, not a promise

A capable SEO agency combines business understanding, technical work, search-intent research, content, measurement and continuous refinement. The aim is not to insert more keywords into a website. It is to make the right pages more useful and discoverable for the customers the business wants to reach.
