Senior SEO advice is only useful if someone can deliver it.
Most businesses looking for an SEO consultant want two things that rarely come together: the judgement of someone who has seen many sites through many algorithm changes, and the capacity to get the recommendations built. A freelance consultant usually brings the first. A large agency often sells the second and hands the account to someone junior.
Our SEO consultancy services are led personally by Gareth Hoyle, Managing Director of Marketing Signals. Gareth sets the strategy, sits in the meetings that matter and stays accountable for the advice. When the work needs doing, specialists in technical SEO and content, Digital PR, AI search and PPC deliver it, so recommendations do not sit in a slide deck waiting for resource.
Gareth also founded Am I Visible?, an AI visibility tracking tool, and Authority.md. He speaks internationally on agentic AI and provides digital due diligence for venture capital and private equity firms. You can see his background on LinkedIn.

The Questions Before The Recommendations
Good SEO consulting starts with the business question, not a crawl report.
Before any audit, Gareth works out what the engagement needs to answer: why organic revenue has stalled, whether a migration is safe to sign off, whether the in-house team is focused on the right work, or what a target company's search position is really worth. Google's own advice on hiring an SEO is to ask for examples of previous work, how success will be measured and whether every change will be shared. That is how we work: findings tied to revenue, written recommendations and full visibility of every change.
- Strategy reviews for marketing directors
- Audits ranked by revenue impact
- Mentoring for in-house SEO teams
- Board and investor briefings
- Migration and replatforming oversight
- AI search strategy and measurement

Consultancy Formats Built Around The Buyer
Our SEO Consultancy Services

Engagements range from a single strategy review to an ongoing advisory role with delivery behind it. Each one is led by Gareth, scoped around the decision you need to make and supported by the specialists the work calls for, including our e-commerce SEO, enterprise SEO and international SEO teams.
Search Strategy That Moved The Numbers
What Senior SEO Consultancy Delivers For The Business
The aim is better decisions about search, made sooner, with the capacity to act on them and one senior person accountable for the advice.
Senior Judgement On Every Decision
The person setting your strategy has run a search agency since 2007, rather than a junior account manager working from a template.
Advice That Gets Delivered
Recommendations go straight to specialists in technical SEO, content, Digital PR and PPC, so they are built rather than parked.
Answers In Commercial Terms
Findings are framed around revenue, leads and risk, in language a board or investment committee can act on.
A Stronger In-House Team
Mentoring and training leave your people more capable, with less reliance on outside help over time.
Lower Risk On Big Changes
Migrations, redesigns and AI search shifts are planned against Google's own guidance and checked before and after launch.
Google And AI Search Together
Strategy covers rankings and visibility in ChatGPT, Gemini, Perplexity and AI Overviews as one plan, not two budgets.
How Our SEO Consultancy Work Runs, Step By Step
1. Define The Question
A first conversation with Gareth to agree what the engagement must answer, who needs the answer and what decision it supports.
2. Review And Diagnose
We gather analytics, Search Console, crawl, backlink and AI visibility data and review it against your commercial goals and competitors.
3. Recommend And Present
Gareth presents a written plan ranked by commercial value to the people who need it, whether that is your team, the board or an investment committee.
4. Deliver Or Advise
Your team delivers with Gareth's guidance, our specialists take on the work, or a mix of both, with progress reported against the agreed measures.
