SEO agency comparison
Choosing an SEO agency is not just about comparing services.
The right partner needs to understand your market, your customers, your website, your competition and — most importantly — what you actually want SEO to produce.
We compare 4Core Digital and SmartSites across SEO focus, services, strategy, reporting, communication, pricing approach and business fit so you can make a more informed decision.
This comparison is based on publicly available information and may change as each agency updates its services.
Quick answer
Both agencies can be suitable for businesses looking to grow through digital marketing, but their positioning is different.
SmartSites is a broad digital marketing agency offering SEO alongside PPC, web design, email and SMS marketing, and social media.
4Core Digital is more heavily centered around SEO and modern search visibility, combining Organic SEO, Technical SEO, Local SEO, eCommerce SEO, AI SEO, GEO and AEO.
So the question isn't simply: "Which agency is better?" The better question is: "Which agency model fits what my business actually needs?"

The biggest difference
SmartSites and 4Core Digital are not positioned in exactly the same way.
SmartSites has built a broad digital marketing offering around SEO, PPC, web design, email/SMS marketing and social media.
4Core Digital is built more heavily around search growth. The core focus is helping businesses improve visibility across traditional search and newer search experiences — from Google and Google Maps to AI-powered search, answer engines and generative search.
This difference matters. If you want one agency to handle several areas of digital marketing, a broad full-service agency may make sense. If SEO is one of your most important acquisition channels and you want a specialist partner deeply focused on search, a more SEO-centered agency may be a better fit.
Neither model is automatically better. The right choice depends on your business.

About
SmartSites is a full-service digital marketing agency founded in 2011.
Its publicly listed services include SEO, PPC, web design, email & SMS marketing and social media.
SmartSites also promotes SEO services including local SEO, ecommerce SEO, national SEO, blogging, technical SEO audits and franchise SEO.
The agency has published a large collection of client work and case studies covering different industries and digital marketing channels.
SmartSites therefore makes sense to consider when a company wants multiple digital marketing capabilities from one agency.
SmartSites is an independent company and is not affiliated with 4Core Digital.

SEO approach
Our SEO approach is built around four areas — the 4Core Growth Framework.
Understand keywords, competitors, search intent and commercial opportunities.

Build useful service pages, informational content, topical coverage and authority.
Connect organic visibility to enquiries, sales, calls, forms and other business outcomes.

Agency model
SmartSites takes a broader digital marketing approach.
Its publicly promoted services combine SEO with paid advertising, web design, email/SMS marketing and social media.
This can be attractive for companies that want several marketing functions managed by one agency. This is a difference in agency model rather than a measure of quality.
Businesses should evaluate whether they need a search specialist or a broader digital marketing partner before choosing an agency.
Modern search
Search is changing. People are increasingly asking longer, more conversational questions and using AI-powered systems to research products, services and businesses.
Google AI Overviews, ChatGPT, Gemini, Perplexity and other AI experiences are changing how information is discovered.
4Core Digital has expanded its SEO offering around these changing search behaviors.
Traditional SEO still matters. AI search does not replace technical SEO, content quality or authority. Instead, modern search optimization builds on those foundations.
AI search optimization is a prominent part of 4Core Digital's current positioning. If AI visibility matters to you, ask any agency you shortlist — including SmartSites — how they currently approach it.

Industries
Neither agency has exclusivity in any industry. Businesses should choose based on specific industry experience relevant to their campaign.
Industries publicly represented across its website and published work may include:
Proof
A good SEO agency should be able to show what changed after its work. That means looking beyond generic statements such as "improve rankings".

SmartSites also publishes a substantial collection of case studies and client results across SEO, PPC and web design.

Pricing
There is no useful universal SEO price. A realistic SEO investment depends on several factors.
Current monthly SEO plan pricing, subscriber pricing and plan inclusions are published on our packages page.
View SEO packagesSmartSites pricing should be confirmed directly with the agency because campaign costs depend on scope and requirements.
The cheapest SEO agency is not necessarily the least expensive option if the campaign fails to produce business results.
Team model
Businesses work with experienced SEO professionals focused on strategy, execution and measurable growth. The goal is to avoid unnecessary layers between the business and the people actually responsible for SEO strategy.
Meet the 4Core Digital team or explore dedicated SEO experts.
SmartSites publicly presents itself as a full-service digital marketing agency with teams across its service lines. Ask who will lead your account, who executes the work and how often you'll speak with them — this is the most reliable way to understand any agency's team model.
Reporting
Regardless of which agency you choose, reporting should go beyond keyword rankings. A useful SEO report should help you understand:
"We focus on connecting search visibility with business outcomes wherever tracking data is available."
