Top SEO Agencies In Hampshire For 2027

Hampshire is a large county with several separate business centres.

A manufacturer near Basingstoke, a solicitor in Winchester, a marine business on the Solent and a retailer near Fleet all compete for different searches, and the county’s agencies are spread out to match. Some of the UK’s longest-running search agencies are based here, alongside smaller teams in market towns, while plenty of firms from London, Sussex and further afield run Hampshire landing pages without a desk in the county.

To build this list of the top SEO agencies in Hampshire, we checked every firm against its own contact and about pages, and against Companies House where useful. Each agency has a verified address in the county, a live website with current activity, and SEO as a real service. We excluded firms that only run a Hampshire landing page, firms that have been absorbed into other brands, and any claim we could not confirm. Our separate Southampton guide covers the city’s own agencies in more depth, so this list looks across the wider county.

Each entry names the Hampshire town where the agency is based, what it does and who it suits, plus verified details such as founding year, team size, named clients, awards and published results.

MRS Digital was founded in 1999 as a search specialist and works from 1 Blue Prior Business Park on Redfields Lane, Church Crookham, GU52 0RJ, on the edge of Fleet. The trading company is MRS Web Solutions Ltd, and the team now numbers more than 40 in-house specialists.

It describes itself as an integrated search agency. SEO comes first, covering technical SEO, international and ecommerce SEO, local SEO, migrations, link and citation acquisition and generative engine optimisation (GEO) for AI search, with paid media, analytics and web development alongside. The agency also builds its own small SEO tools, including an AI crawler access checker.

Its awards list is one of the longest in the region: Best Global SEO Campaign (Large) at the Global Search Awards 2025, Best SEO Campaign (Large) at the European Search Awards 2025, a win at the European Search Awards 2024, three UK Search Awards wins in 2023, and Integrated Search Agency of the Year at the European Agency Awards 2023.

It suits mid-size and large brands that want an award-winning team outside London.

2. Koozai — Search, PPC And Digital PR From A Lee-on-the-Solent Office Since 2006

Koozai was founded in 2006 and has its Hampshire office at Merlin House, 4 Meteor Way, Lee-on-the-Solent, PO13 9FU, part of the Fareham Innovation Centre. It also has offices in Preston and on Old Street in London, which gives a Hampshire base with national reach.

The service mix is broad but search-led: technical, on-page and link building SEO, paid search across Google, Microsoft and Amazon, digital PR, content marketing, paid social and web design, plus SEO and digital marketing audits. Koozai is a Google Partner and Microsoft Partner, holds Cyber Essentials certification and was a UK Digital Excellence Awards finalist in 2025.

The agency reports work for more than 440 clients and brands, an average client lifetime of four years and an average staff tenure of seven years, which points to a stable team. Named clients include TUI, Stannah Lifts, Trulawn, the V&A, Buyagift, Bandai and Cofton Holidays, with published case studies on lead growth for Trulawn and a Mother’s Day campaign for Buyagift. Pricing is quote-based. Koozai suits established consumer and B2B brands that want SEO, paid search and digital PR planned by one experienced team.

3. boxChilli — SEO, GEO And Ecommerce Builds From A 35-Strong Waterlooville Team

boxChilli was established in 2006 and is headquartered at 16 Somerset House, Hussar Court, Waterlooville, PO7 7SG, with appointment-only offices in Southampton and Chichester. The agency has more than 35 in-house specialists.

SEO and AI search optimisation sit at the top of its service list, alongside website design and development and paid media. That mix makes it practical for retailers and service businesses that need a new site and organic growth planned together, and it is a Certified Google Partner and a Semrush certified agency partner.

Published results include an 85% year-on-year rise in traffic and a 44:1 return on ad spend for Time4Nutrition, and a 400% increase in revenue during a peak sales period for Alsoils. Named clients also include Hovertravel, Capital Law, London Bridge Hotel, Italia Conti, Radar Festival, Ocean Safety and The Venues Collection. boxChilli was shortlisted as a finalist at the UK Search Awards 2026. Pricing is quote-based. It is a good fit for ecommerce brands, hospitality groups and professional firms in south-east Hampshire that want SEO and development under one roof.

4. Tillison Consulting — Google Premier Partner Serving Portsmouth And South Hampshire From Cowplain

Tillison Consulting works from the first floor of 33 London Road, Cowplain, PO8 8DF, just north of Waterlooville, and its website has run since 2007. The agency frames its work as a growth system with four levers: search demand through SEO, acquisition through PPC, the website itself, and conversion rate optimisation.

That model suits businesses that want SEO judged by commercial outcomes rather than rankings alone. Tillison is a Google Premier Partner, and client logos on its site include Smiffys, Oxford University Press, Hildon Water, Novatech and Tailored Entertainment.

Its SEO case studies are local and specific. It reports an 85% rise in organic traffic for UK Hot Tubs, a 340% increase in website traffic for Fareham events firm Tailored Entertainment from combined Google Ads and SEO, a 31% rise in organic traffic for Portsmouth chiropractor Health HQ, an average ranking gain of 25 positions for Fareham’s Swan Systems, and a 14% improvement in visibility for primary terms for Hampshire charity Brendoncare. Pricing is set against each client’s goals and budget, and the first consultation is free. Tillison suits SMEs and charities around Portsmouth, Fareham and Havant that want SEO and paid search run as one plan.

5. Leapfrogim — Dedicated SEO Shop With Offices In Fleet And Basingstoke

Leapfrogim, which trades as Leapfrog Internet Marketing through Barceloneta Limited, has two Hampshire offices: Gateway House, 8 Kings Parade, Kings Road, Fleet, GU51 3AB, and Belvedere House on Basing View, Basingstoke, RG21 4HG. It describes itself as an SEO agency focused on getting businesses onto page one of Google.

The service list is short and specialist: SEO services, Google Ads management, a blog writing service and SEO ranking reports. That focus will appeal to small businesses that want a dedicated search provider rather than an agency that also sells branding and print.

Published results are clear. Leapfrogim reports a 183% rise in overall site visibility for KJ Smith Solicitors, while client testimonials describe organic traffic growth of more than 400% over six months for Voice Fairy and more than 550% for Rebecca Couture Millinery, which now ranks on page one for at least 85 keywords. Other clients named on its site include Nordic Rooms, Impact For Good, Atom Studio and The Tech Lounge. Leapfrogim is a Google Partner, and SEO and Google Ads pricing pages are linked from the site. It suits owner-run firms in north-east Hampshire that want straightforward SEO and blog content.

6. Rooster Marketing — Creative And Search Agency At The Mill In Shawford, Winchester

Rooster Marketing, the trading name of Rooster Digital Ltd, has its Hampshire office at The Mill, Shawford, Winchester, SO21 2BP, a few miles south of the city, with further offices in Covent Garden, Birmingham and Manchester. Its registered office is near Southampton.

Rooster is a mixed agency with seven services: branding, strategy, SEO, PPC, social, web development and creative. SEO is a listed practice rather than the whole business, and every new enquiry starts with a free 30-minute discovery call and a free audit covering SEO, conversion rate optimisation and PPC, followed by a monthly retainer.

Its client list is strong for a regional agency. Named clients include Mercedes-Benz, St John Ambulance, Storck, Elekta, Homelodge, Buckfast Tonic Wine and Awards Intelligence, with Hampshire names such as New Forest Ice Cream, Wessex Cardiology and Portsmouth Historic Dockyard. Logos on the site also include Sodexo, Big Yellow, Philips, the NHS and the AA. Rooster does not publish SEO figures, so ask for search-specific case studies. It suits brands around Winchester that want brand, creative and search work from one team.

7. Crakan — SEO And Lead Generation For Local Firms From Fair Oak

Crakan is based in Fair Oak, Eastleigh, SO50 7LG, and says its team brings 15 years of experience. It groups its services into three areas: winning more business through lead generation, SEO, PPC and email marketing; marketing support through web, graphic and content design and branding; and consultancy, temporary resourcing and product prototyping.

SEO and lead generation are flagged as core services on its site, which makes Crakan a practical option for businesses that judge marketing on enquiries rather than traffic. It reports building more than 300 websites and a 98% delivery rate on its SEO services.

Named clients include Denplan, PeGi Group, Swiftie Solar, Aprés Provence, FR Consultants and Southampton Football Club. Managed services are sold as packages built around each client, and prices are not published. Because Crakan shares few SEO case study figures, ask for results in your sector before signing. It suits small and mid-sized firms around Eastleigh, Hedge End and the Itchen Valley that want SEO tied to lead generation and a team they can meet locally.

How To Choose An SEO Agency In Hampshire

Are They Actually Based In Hampshire?

Many results for “SEO Hampshire” come from agencies in London, Sussex or Sheffield that have built a page for every county town. If face-to-face meetings matter, check the contact page for a street address and postcode, then look the company up on Companies House. Every agency in this guide has a Hampshire address on its own site, and the town is named in each entry.

Do You Need A Specialist Or A Full-Service Agency?

Search-led firms such as MRS Digital, Koozai and Leapfrogim put SEO at the centre of every account. Mixed agencies such as Rooster Marketing and boxChilli help when your brand or website needs work at the same time. Tillison Consulting and Crakan sit in between, pairing SEO with paid search and lead generation. A good Hampshire SEO agency should be clear about which of those models it follows.

What Should SEO Cost In Hampshire?

As a typical UK market range, local SEO for a small business usually costs £400 to £1,500 a month. National campaigns for growing SMEs tend to sit between £1,500 and £4,000 a month, and ecommerce or enterprise work with digital PR often runs from £4,000 to £10,000 a month or more. Be wary of low fees that do not explain what work is included, and ask whether the price covers content and links or only reporting.

Can They Show Results With Named Clients?

Ask for case studies with named businesses, a starting position and a measurable outcome, such as organic revenue, leads or visibility over a set period. If an SEO company Hampshire businesses are considering cannot name a client in your sector, ask to speak to one by phone before you sign.

How Long Before You See Results?

Most campaigns take three to six months to show clear movement, and competitive national or ecommerce terms can take a year or more. Technical fixes on an established site can show results within weeks, and local map pack changes often move faster than national rankings. Agree milestones at the start so you can judge progress before rankings move.
