SEO Consultant: what they do and how to choose one
An SEO consultant diagnoses why your website doesn't rank on Google and builds a plan to fix it. Learn what they actually deliver, how to evaluate one, and when a small business really needs one.
Key points
You have a website and you do not appear on Google for the searches that matter. Or you appear, but not in the positions where people actually click. Or you have paid for SEO services before that produced no measurable result. In any of these three situations, the question is always the same: do I need an SEO consultant?
This guide explains exactly what an SEO consultant does, how they differ from an agency or a freelancer, when a small business genuinely needs one, and how to evaluate one without getting trapped by promises that cannot be fulfilled.
What an SEO consultant actually does
An SEO consultant is not someone who “gets you on Google”. Nobody controls the Google algorithm. What they do is diagnose why your website does not appear for the searches that matter to you, and create a plan to fix it.
The concrete work divides into five main blocks:
1. Technical audit
Reviews whether the site is crawlable (Google can read every page), whether meta tags are unique and within character limits, whether there are 404 errors, whether HTTPS is correctly configured, and whether Core Web Vitals (LCP, INP, CLS) meet Google’s standards. A slow or technically broken website does not rank, regardless of how good the content is.
2. Keyword research
Identifies what searches your potential customers make, which keywords have real volume, what the search intent is (informational, commercial, transactional) and what the competition level is for each. Without rigorous keyword research, any published content is a data-free guess.
3. Content plan
With keywords identified, the consultant designs which pages to create, in what order, with what internal structure, and how to interconnect them to build topical authority. This is not about publishing random blog posts: each piece of content must target a specific query and reinforce the rest of the site.
4. On-page optimisation
Reviews and improves page titles, meta descriptions, heading structure (H1, H2, H3), image alt text, Schema.org structured data and internal link building. All these elements must align with the target keyword of each page.
5. Tracking and reporting
Sets up Google Search Console and Google Analytics, defines the conversions to measure (form completions, calls, purchases), and delivers monthly reports with current positions, trend data and planned actions for the next month. A consultant who does not measure cannot demonstrate impact.
SEO consultant vs SEO agency vs freelancer
Not every situation calls for the same profile. The distinction matters because it determines what budget you need and what working relationship will be established.
Independent consultant or small team: takes responsibility for strategy and oversees execution. Usually the single point of reference for all SEO decisions. Best option for SMBs that need coherence between web and content, direct access to the decision-maker, and do not want to pay a large agency to attend meetings with junior profiles.
SEO agency: has differentiated teams for technical SEO, content, link building and paid. Scales well when execution volume is high: hundreds of pages, multi-language campaigns, large link building projects. The risk is the distance between whoever sells the service and whoever executes it.
Task-specific freelancer: content producer, link builder or technical specialist. Ideal for covering a specific one-off need. Not strategic by nature: works to instructions, not to business objectives.
For most SMBs in the Iberian market, the first option gives the best results per euro: a consultant or small team that understands the business and handles the full cycle.
Signs that a small business genuinely needs an SEO consultant
There are concrete situations where hiring an SEO consultant makes clear sense:
- Your website generates leads or sales (forms, online booking, e-commerce) and your Google position directly affects revenue. In this case, improving rankings has a calculable ROI.
- Direct competitors appear above you for key commercial searches and you do not know why.
- You have published content for months with no movement in positions, which usually indicates a technical or strategic problem not visible without diagnostic tools.
- Your website was built by an agency that did not include any SEO configuration (no Search Console, no Schema.org, no sitemap).
- You are launching a new product or service and want organic traffic to be a channel from day one.
When you do NOT need an SEO consultant (yet)
If your website is a three-section presentation page with no form, the problem is not the SEO. The problem is that the site is not a sales channel. The first step is building a website that works: service pages, contact form, content that answers real customer questions. SEO without a correct technical foundation produces no results.
Similarly, if the business operates in a very local niche with little competition, basic Google Business Profile optimisation and a few reviews generate more impact than a full SEO strategy.
How to evaluate an SEO consultant: concrete criteria
When assessing an SEO consultant, five questions always reveal professional quality:
1. Do they ask for Google Search Console access from the start?
Without Search Console there is no real diagnosis. A consultant who proposes actions without first reviewing your current site data is working blind.
2. Can they show case studies with measurable results?
Not generic testimonials, but concrete examples: “client X in sector Y, initial positions, positions at 6 months, monthly organic traffic before and after”. If they have none, or if all examples are under NDA with no data at all, that is a warning sign.
3. Do they define a clear success metric in the contract?
The metric might be: positions for 10 target keywords, monthly organic traffic, or organic conversions. What it cannot be is “improve online visibility” with no associated number.
4. Do they explain their content strategy?
Modern SEO depends on content. A consultant who does not discuss content, natural link building and topical authority building is working with 2015 techniques.
5. What is their contract and notice policy?
Contracts without a clear exit clause, one-month commitments (impossible to demonstrate value in), or very low monthly fees that do not cover even a basic audit: all three should be treated with scepticism.
Red flags: suspicious promises and opaque structures
The SEO sector has more low-quality practitioners than almost any other area of digital marketing. These are the patterns to recognise:
“I’ll get you to number 1 on Google in 30 days.”
Nobody can guarantee a specific Google position. The algorithm depends on hundreds of factors, many of which are outside the consultant’s control. A promise like this is either dishonesty or ignorance.
Artificial bulk link-building schemes.
Buying links in bulk (black-hat SEO) can produce fast results that disappear when Google updates its algorithm, and in extreme cases generates manual penalties that take months to reverse. A good consultant builds authority through quality content and genuine editorial relationships.
Very low monthly fees with no scope explanation.
A minimal technical audit takes 8-15 hours. If the monthly fee does not cover that time at market hourly rates, something does not add up. Either the work is superficial, or below-market wages are being paid, or what you are paying for is access to automated tools with no human supervision.
No monthly report and no tool access.
The client must have access to Google Search Console and Google Analytics at all times, and must receive a readable monthly report with real data. A consultant who “manages the tools for you without giving you access” is working with data you cannot verify.
Contracts without a defined success metric.
If the contract does not explicitly state how success will be measured, the consultant can never be declared to have failed. Every professional SEO engagement must include a primary metric, a timeframe and a periodic review.
How much does an SEO consultant cost
In the Iberian market, the real range is wide. A freelancer handling specific tasks may charge 300-600 EUR per month. A consultant with demonstrated experience in competitive markets quotes 1,500-3,500 EUR per month for an active account. Larger projects (multilingual sites, e-commerce, national SEO) can exceed 5,000 EUR per month.
Factors that justify a higher price:
- Competitiveness of the target market (national searches vs. local searches in a lower-competition language)
- Number of pages to manage and content publication frequency
- Technical scope (a 50-page WordPress site has very different problems from a 10,000-SKU e-commerce)
- Consultant experience: years of track record, documented case studies, access to paid research tools
A consultant who quotes without first diagnosing your site and your competition does not know what the work is worth. The price must come from the scope, not the other way around.
The serpixel model
serpixel (Clever European Business, S.L.) is an agency specialising in custom AI agent implementation for small and medium businesses, based in Catalonia, Spain. Web design and SEO remain one of four products, and it works differently from traditional SEO consultancy for one concrete reason: we do not separate web design from SEO.
Most SMBs end up paying three separate providers: the agency that builds the website (no technical SEO), the consultant doing keyword research (no ability to touch the code), and the content writer (no access to ranking data). The result is incoherent and slow.
The serpixel model integrates all four pieces into one product: website architecture built to rank from day one (100/100 PageSpeed, automatic Schema.org, hreflang across all languages), SEO strategy based on real Search Console data, AI-supervised content structured for Google and for AI search engines such as ChatGPT and Perplexity, and a monthly report with positions, traffic and planned actions for the next month.
The process starts with a 30-minute discovery session. No commitment. No published fee: scope and price are determined after understanding your business, your competition and your objectives.
Everything we build, the code, the content and the data, is the client’s property from day one.
