Choosing an SEO Agency in the UK: Services, Packages and Costs

Buying SEO should be a decision about which useful changes will be made to your website, not a competition to see which agency promises the most keywords. If you are comparing UK SEO companies, this guide explains what to ask for, which costs need clarifying and how to judge results without being distracted by impressive-sounding traffic claims.

If you already have an established website, start with our SEO services overview. For defined monthly options, see SmartyX SEO packages and pricing. Those pages explain the current scope and starting prices; this guide explains how to evaluate any supplier, including us.

1. Find out what needs improving before choosing a package

A useful proposal begins with the business. Which services are most profitable? Which products or locations matter? Can customers already find the website for related searches? Is the problem weak search visibility, unhelpful landing pages, poor conversion or a mixture?

Ask the supplier to inspect existing search data and the website before recommending a long programme of new articles. Improving an existing service page that already receives relevant search impressions can be more useful than publishing a broad blog post with no clear commercial purpose. Our published four-website Search Console comparison is an example of how to present search metrics with date ranges and limitations instead of treating clicks as confirmed customers.

2. Ask what monthly SEO work is actually included

SEO packages vary greatly. A report-only service is different from a team that implements technical fixes, improves landing pages and maintains a useful internal-link structure.

• Technical SEO: crawlability, indexation, canonical URLs, redirects, sitemap health, structured data and performance issues where they affect important pages.
• On-page SEO: clearer page purpose, search-intent alignment, useful headings, product and service information, accurate snippets and conversion routes.
• Internal linking: descriptive, contextual connections between relevant service pages, guides, categories and case studies.
• Local SEO: accurate business information, genuine service-area relevance, Google Business Profile maintenance and appropriate citation work.
• Ecommerce SEO: category organisation, product discoverability, duplicate or filtered URLs, internal navigation and buying information.
• Reporting: the URLs changed, work completed, baseline and next priorities, as well as search trends.

Ask whether implementation is included or whether you will be handed a list of recommendations to send to a separate developer. A monthly retainer should make that distinction clear.

3. Compare costs against the time and work provided

The cheapest package is not automatically best value, and an expensive package is not proof of better delivery. A single-location trades business, a multi-service national company and a growing online store need different amounts of work. Ask about setup work, continuing monthly work, content creation, development time, access to analytics and any separate outreach budget.

SmartyX currently publishes three starting points for standalone ongoing SEO: Local SEO from £495/month, Growth SEO from £895/month and Ecommerce SEO from £1,495/month, subject to the agreed scope. The live SEO packages page is the source for up-to-date prices and inclusions. Website-build packages are a different product; compare them separately at Website Design & SEO Packages.

4. Look for evidence that can be checked

Good case studies tell you what was delivered, which website was involved, when a result was measured and what the numbers represent. Search impressions are not enquiries. Search clicks are not confirmed customers. Average position across a property is not a guaranteed ranking for one keyword.

For example, SmartyX publishes dated Search Console evidence relating to Kinmel Campers on our client work and case studies pages, alongside the work delivered. Those are historical snapshots, not a forecast of what another business will achieve. Ask any agency for similarly transparent evidence.

5. Understand the difference between local, national and ecommerce SEO

Local service businesses

For a plumber, plasterer, garage or clinic, commercial service pages, trust, consistent contact information, relevant reviews and a well-managed Google Business Profile may matter far more than publishing articles every day. See our local SEO services for the approach.

More competitive or multi-location businesses

Established companies often need a wider programme: technical review, strong pages for distinct services, genuine location evidence and relevant supporting material. Do not confuse unique location pages with near-duplicate doorway pages made by changing a town name.

Online shops

Ecommerce businesses need useful product and category structures, navigation, indexation controls and content that answers actual buying questions. See our ecommerce SEO services.

6. Be careful with backlink promises

Links can help people discover relevant businesses and can be a signal to search engines, but volume alone is not a quality measure. Ask where links would come from, why those websites would genuinely mention your business and whether you are paying for a placement. Avoid companies promising hundreds of backlinks from automated directories, unrelated guest posts or sitewide footer networks.

Google’s published spam policies warn against links created primarily to manipulate rankings, including widely distributed template or footer links. A sensible off-site strategy prioritises genuine client referrals, useful editorial mentions, partnerships and accurate business profiles. Paid placements should use the appropriate link attributes.

7. Make sure you control your website and data

Before signing, confirm ownership and access: your domain, website hosting, WordPress administrator account where applicable, Google Search Console, analytics, Google Business Profile and any advertising accounts. Ask what happens to the website, reporting and work if the agreement ends. A plan should be commercially useful without trapping you inside a provider’s systems.

8. Agree on how success will be measured

Start from a dated baseline and compare like with like. Useful measures include impressions and clicks for important non-branded searches, landing-page visibility, useful enquiries, conversions and the quality of customer requests. Seasonality, website changes and wider search updates all matter when reading a graph.

Search Console data is not a substitute for recording whether an enquiry form works or whether a customer has paid. You can learn more about search metrics from Google Search Console Help.

Questions to ask an SEO agency before signing

• Which three pages or technical issues would you prioritise first, and why?
• How much hands-on implementation does the monthly fee include?
• Are you improving existing pages before proposing new ones?
• What evidence supports your case studies, and what period was measured?
• How will you build relevant links without risking link spam?
• Will I keep access to my site, content, Google accounts and reporting?
• What is included, excluded or charged separately?
• How will you report completed changes, organic enquiries and next steps?

Choosing a sensible next step

You do not need to commit to a large SEO contract to discover whether a provider understands your business. Start by identifying the important pages, the search opportunities and the fixes that would actually improve customer experience. Then agree a realistic scope that the provider can deliver and demonstrate.
