SparkSEO contact and verification route
A provider can describe expertise for pages, then leave the identity of the contracting business unclear. For example, a marketing lead may receive an invoice, yet struggle to match the name on it to a public address or company record.
The practical fix is a compact record that names the legal entity, registration details and a direct contact route. Spain's LSSI Article 10 requires information-society service providers to make identity, address, email, relevant registry details and tax ID permanently, easily, directly and freely accessible.
| Fact | Verification route | How to use it |
|---|---|---|
| Legal name | Spark SEO SL | SparkSEO is the trading brand of Spark SEO SL. Match this legal name to your proposal and invoice. |
| NIF/CIF | B88863188 | Use CIF B88863188 to identify Spark SEO SL in your contracting and invoicing records. |
| Registered address | Calle Diputacio 211P. BA., 08011 Barcelona, Spain | Use this registered address for company correspondence and compare it with your proposal and invoice. |
| Commercial Registry | Request before signing or paying | Ask whether registry details apply, then compare any reference with the official record. |
| Operating base | Barcelona, Spain | This describes where SparkSEO is based. It is not a substitute for the registered address. |

Transparency makes an SEO relationship easier to assess
SEO work can involve access to a website, analytics and monthly spend, so a blurred company identity creates an avoidable business risk. Imagine a finance team that cannot tell whether a scope, invoice and support conversation refer to the same legal entity.
SparkSEO explains its working model and provides a direct route to request contracting details, so you can compare what is promised with the documents you receive. Clear information supports better questions before work begins and reduces pressure to rely on sales language alone.
A traceable provider
A legal name, tax ID and registered address give a buyer stable details to compare across a proposal, invoice and public record.
A readable commitment
Monthly billing and plain cancellation terms make the financial commitment easier to review before technical work begins.
A reachable contact
A published email and office hours show where questions can go when a decision needs a human response.
A safer incentive
Our performance model measures non-branded keyword progress per landing page, so risky shortcuts that create later drops work against our fee.
How to verify a company before you sign
A polished website can make a provider look established while leaving practical checks unfinished. For example, an operations manager may have a company name but no tax ID, registration reference or clear way to confirm that the company is active.
A short verification sequence keeps the process factual. It works because each step compares a different piece of evidence instead of treating a logo, ranking claim or testimonial as proof of identity.
Record the legal identity
Compare the published legal name, Spark SEO SL, and CIF B88863188 with your proposal and invoice. Small differences in a legal name can matter, so ask for clarification before treating records as a match.
- Legal entity name
- NIF/CIF
- Registered address
Search the official registry
Search the Spanish Commercial Registry using the legal name or NIF/CIF, then request the available company information. Compare the identifying data, address and registration reference with the documents you received, because a single match is less useful than a consistent record.
- Search by name or NIF
- Check registration details
- Review available filings
Match the commercial documents
Compare the entity name, tax ID and address across the registry result, proposal and invoice. Ask why any material difference exists before approving payment, because a clear explanation is easier to assess before a project starts.
- Proposal
- Invoice
- Registry record
Test the service contact
Send a focused question to sales@sparkseo.com during the published hours and ask who will manage the account. A direct response helps you confirm the route for commercial questions before access to your site or data is granted.
- Email response
- Manager contact
- Working hours
Billing terms that keep the work and budget visible
Long commitments can hide whether an SEO plan still fits the business after priorities change. A common example is a campaign that needs to pause after a site launch moves or a market closes, while the client cannot tell what work has been paid for.
SparkSEO uses a monthly model with a practical cancellation path. This structure keeps the budget review close to the work completed and gives both sides a reason to document scope and progress clearly.
- Monthly billing Fees are billed monthly. The agreed scope should state the base fee and what is being measured, rather than relying on an implied price or a vague package name.
- Cancel at any time A client may cancel at any time. The cancellation conversation should identify the last paid period, outstanding access needs and the handover materials that are useful for the next team.
- Finish paid work If a client stops paying, SparkSEO finishes the work already paid for. The client keeps the results of paid work, which makes project ownership less dependent on an ongoing subscription.
- Unused budget requests On request, and where possible, SparkSEO refunds unused budget. The request should identify the paid period, unused scope and supporting invoice so the decision is based on documented work.
- Review performance records Weekly and monthly reporting separates ranking performance from progress work such as audits, content and backlinks. Read the SEO reporting approach with the invoice because activity and outcomes answer different questions.

Compare documented facts with vague agency claims
SEO buyers sometimes see confidence presented as evidence. For example, a provider may promise rapid rankings but omit the entity that will bill, the reporting method and the terms for ending work.
A facts-first standard shifts the discussion from prediction to proof. It helps you assess whether the provider can explain the process, commercial terms and accountability before asking them to optimize a site.
Vague claims
- A brand name with no legal entity or tax ID
- A contact form with no direct email or office hours
- An open-ended promise with no reporting rhythm
- A cancellation policy that appears after payment
Documented facts
- Legal details requested in writing before payment
- A direct email and published availability
- Monthly reports linked to agreed work and measures
- Cancellation and unused-budget terms stated in advance
A simple review before an SEO engagement
Buying SEO often combines commercial, technical and reputation decisions, which can leave the final check to the last minute. Imagine a Barcelona clinic preparing to grant an agency access to its website and Google Business Profile, but the clinic manager has only a proposal and a brand name.
A short review can resolve the basic questions before access changes hands. It protects both sides because the scope, legal identity and reporting expectations are recorded before the first task begins.
This is a hypothetical example. The clinic manager requests the legal name and NIF/CIF from SparkSEO in writing, checks that they match the proposal and invoice, requests the company record through the official registry service, and writes to the published contact email to confirm the project manager. The manager then reads the SEO audit service scope and the first 90 days plan before approving access.
- Match legal name, NIF/CIF and address across documents.
- Confirm the work scope and monthly reporting route.
- Record cancellation and handover expectations in writing.
- Grant only the access needed for the agreed first stage.
The agency relationship begins with verifiable records and a shared operating plan. The clinic has not been promised a ranking outcome, but it can assess who is responsible, what is being done and how progress will be reported.
Company facts help people assess trust before search systems do
Visitors cannot evaluate an agency's competence from rankings alone, especially if no one is clearly accountable for the site. For example, a buyer researching several providers may leave when they find no address, direct contact or evidence that a real organisation stands behind the claims.
Transparency serves the human decision first. It also aligns with the signals Google describes for helpful information: clear sourcing, background about the publishing site and accurate authorship can help users decide whether to trust content.
Stanford's web credibility guidelines state that a site should show that a real organisation is behind it, and identify a physical address as the easiest way to do so. The same guidance says clear contact information can build credibility. For SparkSEO, the practical requirement is to publish verified legal identity and address details, not decorative proof points.
Google's people-first content guidance says its systems aim to prioritize helpful, reliable information created to benefit people. Google asks publishers to make clear who created content and says fabricated creator profiles make a page untrustworthy to users and automated quality systems. Accurate company facts therefore support a human-first website purpose, while invented names, reviews or credentials create the opposite effect.
SEO itself cannot guarantee a ranking. Google states that no one can guarantee a number-one result, a useful reminder to judge an agency by transparent process, evidence and reporting rather than certainty claims. See SparkSEO's performance-based SEO model for how non-branded keyword movement is measured per landing page.
The company facts that matter in a proposal
Legal and SEO terms can make simple checks harder than they need to be. For example, a business owner may see CIF on an old invoice and NIF on a current record, then assume the mismatch proves a problem without first understanding what each field identifies.
Plain definitions make a proposal easier to review with finance, legal and marketing colleagues. They also help separate evidence about the contracting company from a description of the SEO service.
- Legal name
- The formal name of the entity that signs the agreement and issues the invoice. It may differ from the public brand name.
- NIF/CIF
- A Spanish tax identification reference used to identify the relevant person or entity. This page uses NIF/CIF because buyers may see either label in business documents.
- Registered address
- The address recorded for the entity for formal correspondence and public registration purposes. It is distinct from a general statement that a team is based in Barcelona.
- Commercial Registry
- The Spanish public registry where a company may have registration data. Record the company name, NIF/CIF and registration reference before carrying out a registry check.
- Non-branded keyword
- A search query that does not include the client's company name. SparkSEO uses these terms to measure search visibility beyond people already looking for the brand.
- SEO manager
- The personal day-to-day contact who coordinates questions, reporting and next steps during Barcelona working hours. Learn more about the SEO process.
Read the working details behind the company facts
Company details are one part of a sound buying decision, but they do not explain how a project will be planned or measured. For example, a verified legal entity still needs a transparent scope, realistic timeline and meaningful reporting before it earns access to a website.
These resources help you test the practical side of an SEO proposal. They are useful when you want to compare work methods and evidence without confusing company verification with a promise of traffic or rankings.
