An Amsterdam business may need Dutch-language search content, English-language pages for international customers, local discovery, or technical help across all three. An SEO bureau should begin by understanding which customers the business serves and what action matters after a search visit. Search-engine optimization helps a site become understandable and useful; it does not buy a fixed position in Google results.
Define the market and website
List the products or services, service areas, languages, and types of customers. A local shop needs accurate opening hours, location details, and a useful Google Business Profile. A B2B exporter may need clear multilingual service pages, case evidence, and lead forms. Ask a prospective bureau to inspect the current site, major conversion paths, mobile usability, and index coverage before proposing a content volume or link quota.
Google's SEO Starter Guide recommends descriptive pages, sensible navigation, and information that helps people decide whether a result is relevant. Google says local results are mainly shaped by relevance, distance, and prominence. An agency can improve business information and site quality, but cannot make a distant company appear geographically closer to a searcher or pay Google for a better organic local rank.
Ask for a useful proposal
Audit
Request a prioritized list of technical and content issues, with evidence and estimated effort.
Languages
Confirm who writes and reviews Dutch and English copy and how equivalent pages will be maintained.
Local presence
Check business details, categories, reviews, photos, and location-page accuracy without inventing addresses.
Measurement
Track qualified enquiries, sales, and relevant search visits as well as rankings for a small set of terms.
Assess the working relationship
Google's hiring guide advises asking an SEO to explain recommendations and be wary of guarantees. Require ownership of the website, analytics, Search Console, and business profile to remain with the company. Ask how the bureau will document changes, who can approve them, and how it handles an incorrect listing or technical regression. A cheap offer that creates doorway pages or low-value links can leave expensive cleanup later.
Compare proposals on the same goals and available budget. An agency can coordinate research, content, technical fixes, and measurement; it cannot certify future search traffic or sales. Review progress against a baseline over a realistic period and consider other changes such as seasonality, advertising, and product demand. Use the linked Google documentation for current platform guidance rather than an undated ranking trick.
