A Practical Guide to Selecting an SEO Company

What is "Companies Doing SEO"?

"Companies doing SEO" refers to specialized service providers that help businesses improve their visibility and ranking in organic (non-paid) search engine results. It involves the strategic process of optimizing a website's content, technical structure, and authority to attract qualified traffic from search engines like Google.

Businesses often struggle with selecting a capable, trustworthy SEO partner due to a market flooded with inconsistent claims, opaque pricing, and a high risk of engaging a vendor that uses ineffective or risky tactics.

Technical SEO — Optimizing website infrastructure (speed, crawlability, mobile-friendliness) so search engines can find and index content efficiently.
On-Page SEO — Optimizing individual web pages through content, titles, headings, and meta-data to rank for specific keywords.
Off-Page SEO — Building a website's authority and reputation primarily through earned backlinks from other reputable sites.
Content Strategy — Planning, creating, and promoting content that answers user queries and establishes topical authority.
Local SEO — Optimizing a business's online presence to attract customers from local searches, including managing Google Business Profiles.
SEO Audits — Comprehensive analyses that identify technical issues, content gaps, and missed opportunities on a website.
Performance Tracking — Monitoring key metrics like rankings, organic traffic, and conversions to measure ROI and guide strategy.

This topic is most critical for founders, marketing leaders, and procurement specialists who need to drive sustainable growth through organic channels but lack the in-house expertise or time to execute a complex SEO strategy effectively. Partnering with the right company solves the core problem of missed market opportunity and inefficient marketing spend.

In short: Engaging a professional SEO company is a strategic investment to systematically increase qualified website traffic and revenue through search engines.

Why it matters for businesses

Ignoring professional SEO or partnering with an ineffective provider leads to stagnant growth, wasted budget, and a competitive disadvantage as rivals capture your potential customers directly at the moment of search.

Missed Revenue Opportunities → A competent SEO company targets high-intent search queries, directly connecting your product or service with users actively looking for solutions, which increases conversion rates.
Inefficient Marketing Spend → Organic search traffic, once established, provides a cost-effective, compounding return, reducing long-term reliance on more expensive paid advertising channels.
Loss of Market Credibility → High search rankings act as a trust signal to potential customers; failing to appear for relevant searches can make your business seem less authoritative than competitors.
Poor Website User Experience → A core part of SEO is improving site speed, navigation, and mobile performance, which directly reduces bounce rates and improves engagement for all visitors.
Inability to Scale Content → Professional SEO firms provide the strategy and execution to produce content that consistently attracts your target audience, something internal teams often struggle to prioritize.
Vulnerability to Algorithm Updates → Search engines frequently update their ranking algorithms; a qualified partner monitors these changes and adapts your strategy to protect your traffic from sudden drops.
Wasted Management Time → Vetting, hiring, and managing freelance or in-house SEO talent is a complex, time-consuming process that distracts from core business activities.
Risk of Penalties → Unethical "black-hat" SEO tactics can lead to manual penalties from search engines, causing catastrophic drops in traffic; a reputable company uses only safe, sustainable methods.

In short: Professional SEO delivers sustainable customer acquisition, builds brand authority, and protects your online assets from risk and obsolescence.

Step-by-step guide

Choosing an SEO company can feel overwhelming due to jargon, opaque proposals, and fear of a long-term, costly mistake.

Step 1: Diagnose Your Internal Needs

The obstacle is not knowing what you actually need, leading to mismatched services. Start with an honest internal assessment before speaking to vendors.

Define your primary goal: Is it more leads, e-commerce sales, brand awareness, or local foot traffic?
Audit your current state: Use Google Analytics and Search Console to document current organic traffic, top pages, and keyword rankings.
Determine your budget and resources: Decide who will manage the relationship internally and what level of monthly investment is sustainable.

Step 2: Create a Longlist of Potential Partners

The pain is a shallow or biased search. Cast a wide net using multiple sources to avoid limiting your options to the most marketed agencies.

Search B2B marketplaces like Bilarna, industry directories, and peer recommendations. Look for providers that specifically mention your industry, business size, or the goals you identified in Step 1. Avoid agencies that rank for generic "SEO services" but show no specialization.

Step 3: Scrutinize Public-Facing Signals

The risk is being swayed by a polished sales pitch over substance. A company's own digital footprint is its best case study.

Analyze their website: Is it fast, modern, and informative? Do they practice what they preach in their own content and technical SEO?
Review their content: Look for blogs, guides, or case studies that demonstrate deep expertise, not just generic sales content.
Check their online reputation: Read third-party reviews on platforms like Clutch or G2, and note how they respond to criticism.

Step 4: Evaluate Proposals Strategically

The frustration is comparing apples-to-oranges proposals. A good proposal is a strategic document, not just a list of tasks.

Avoid proposals that are vague, promise #1 rankings for easy keywords, or guarantee specific results in a short timeframe. A strong proposal will clearly outline:

A diagnosis of your site's specific issues and opportunities.
A strategy tied directly to your business goals from Step 1.
A clear scope of work, deliverables, and reporting schedule.
Transparent pricing and contract terms.

Step 5: Conduct Rigorous Vendor Interviews

The mistake is not asking the hard questions. Use the interview to assess cultural fit, communication style, and strategic thinking.

Prepare a question list. Ask about their approach to a specific challenge on your site. Request to speak to your potential account manager. Inquire about how they handle disagreements or strategy pivots. Their answers reveal more than any case study.

Step 6: Start with a Defined Pilot Project

The fear is being locked into a long, expensive contract with an underperforming partner. Mitigate this by beginning the relationship with a discrete, time-bound project.

Propose an initial engagement such as a technical SEO audit, a content gap analysis, or a 3-month strategy for one section of your site. This allows you to evaluate their work quality, communication, and results on a lower-risk investment before committing to a full retainer.

In short: A methodical process of internal diagnosis, wide sourcing, evidence-based evaluation, and a risk-mitigating pilot project leads to a successful, long-term SEO partnership.

Common mistakes and red flags

These pitfalls persist because businesses often lack the framework to evaluate technical claims and are pressured by the desire for quick results.

Choosing based solely on price → Low-cost providers often use templated, low-impact tactics or outsourced labor, delivering minimal value. Fix: Evaluate value (expected ROI) over cost, and be wary of prices significantly below market rate.
Falling for guaranteed rankings → No ethical company can guarantee specific rankings; search algorithms are proprietary and constantly changing. Fix: Treat any guarantee as a major red flag and seek partners who guarantee work and reporting, not specific outcomes.
Over-relying on a single metric → Focusing only on keyword ranking ignores more critical metrics like organic traffic, conversion rate, and revenue. Fix: Require that reporting ties SEO performance directly to your core business KPIs from the start.
Neglecting the contract scope → Vague contracts lead to scope creep, unexpected additional costs, and disagreements. Fix: Ensure the statement of work explicitly details deliverables, communication protocols, and what is not included.
Ignoring communication style → Poor communication creates frustration and strategic misalignment. Fix: During interviews, assess response times, clarity, and whether they explain complex concepts in an understandable way.
Not checking for hidden links or spam tactics → Some providers use risky link-building schemes that can incur penalties. Fix: Ask directly about their link-building philosophy and require full transparency on all placed links.
Selecting a vendor without relevant experience → An agency great for B2C e-commerce may fail at complex B2B lead generation. Fix: Prioritize providers with verifiable case studies or client testimonials in your sector or with similar business models.

In short: Avoiding these common errors requires focusing on strategic fit, transparent practices, and business outcomes over cheap promises and vanity metrics.

Tools and resources

The challenge is knowing which type of tool solves which problem, as the SEO software landscape is vast and specialized.

SEO Platform Suites — Comprehensive tools like Ahrefs, Semrush, or Moz address keyword research, competitive analysis, backlink tracking, and site audits. Use these for deep strategic planning and ongoing competitor monitoring.
Technical SEO Crawlers — Tools like Screaming Frog or Sitebulb are essential for deep technical audits. They crawl your website like a search engine to identify issues with links, redirects, page speed, and metadata.
Performance Analytics Dashboards — Platforms like Google Looker Studio or Databox are used to unify data from Google Analytics, Search Console, and CRM systems. They solve the problem of scattered data by creating clear, actionable performance reports.
Rank Tracking Tools — While a limited metric, tools that track keyword ranking positions are useful for measuring visibility for core terms. Use them to track progress on specific, high-value keyword targets.
Content Optimization Plugins — Tools like Clearscope or MarketMuse help analyze top-ranking content and provide data-driven suggestions to improve your own content's relevance and comprehensiveness.
Backlink Analysis Tools — A subset of platform suites, these are critical for evaluating the quality of your own backlink profile and researching competitors' link-building strategies to identify opportunities.
Local SEO Management Platforms — Tools like BrightLocal or Whitespark help manage and track citations, reviews, and local pack rankings for businesses with physical locations or service areas.
B2B Provider Marketplaces — Platforms like Bilarna help solve the initial discovery and vetting problem by aggregating verified SEO companies, allowing for efficient comparison based on your specific criteria.

In short: The right toolkit combines broad platform suites for strategy, specialized crawlers for technical health, and analytics dashboards to prove business impact.

Frequently asked questions

Q: How much should a professional SEO service cost?

SEO pricing varies widely based on scope, agency size, and market. Retainers can range from €1,500 to €10,000+ per month for ongoing management, with audits or projects priced separately. The key is to align cost with expected value. A reliable next step is to define your goals and request detailed proposals from several providers to compare scope and pricing models, rather than searching for a standard "market rate."

Q: How long does it take to see results from SEO?

Unlike paid ads, SEO is a long-term strategy. Technical fixes can yield visibility improvements in weeks, but sustained growth in traffic and rankings from content and authority building typically takes 4 to 12 months. The main takeaway is to view SEO as a long-term investment and choose a partner that sets realistic expectations and focuses on foundational, sustainable work.

Q: What's the difference between an SEO consultant and an SEO agency?

An SEO consultant is typically an individual expert offering strategic guidance, often suited for businesses with an in-house team to execute. An agency provides a full team (strategists, writers, technicians) to handle execution. The choice depends on your internal resources.

Choose a consultant if you need high-level strategy and have execution capacity.
Choose an agency if you need a full-service team to implement the strategy.

Q: Can I do SEO myself instead of hiring a company?

Yes, for basic foundations. You can optimize page titles, improve site speed, and create good content. However, professional SEO requires deep, constantly updated expertise across technical, content, and analytical domains. The practical next step is to conduct a free technical audit using a tool like Google's PageSpeed Insights or a crawler, and if the issues seem complex or time-consuming to fix, that's a clear signal to seek expert help.

Q: What should be included in a good SEO report?

A good report moves beyond rankings to show business impact. It must include:

Organic traffic and conversion trends.
Progress on key performance indicators (KPIs) tied to your goals.
A summary of work completed and its rationale.
Clear insights and recommended next steps.

Before signing a contract, request a sample report to ensure it provides actionable insight, not just data.

Q: How do I know if my current SEO company is doing a good job?

Evaluate them against your original business goals. Are you seeing a positive trend in qualified organic traffic and conversions? Is their communication proactive and clear? Do they explain their strategy and adapt it based on data? If the answer is "no" to these, conduct an independent site audit or seek a second opinion from a new provider to benchmark performance.
