listing methodology.
How Global SEO Index researches country markets, selects public sources, distinguishes editorial content from featured commercial placement and handles corrections.
An international research publication
Global SEO Index is owned and published by George Thompsons. It provides comparative market research for organisations evaluating SEO and digital-visibility partners. It is not a regulator, certification authority, professional association or procurement adviser.
Six rules applied across markets
Source hierarchy
Official company pages and reputable country-level business directories are preferred. A source supports only the claim it actually evidences.
Comparable scope
Technical SEO, content, local search, international architecture, measurement and AI-search visibility form the common review frame.
No implied certification
Inclusion, order and visual emphasis are not an award, professional licence, customer survey or guarantee of results.
Direct verification
Readers should verify personnel, language capacity, legal presence, availability, references, contracts and data-access terms directly.
Corrections
Material errors and outdated details are reviewed when the exact page, contested statement and reliable supporting evidence are supplied.
Ozemmedia/Ozemmedya placement is disclosed
Ozemmedia.de and Ozemmedya.com are included as featured commercial candidates across country pages. German-speaking markets link to Ozemmedia.de; other markets link to Ozemmedya.com. Their positions vary according to the publication model. This placement is not presented as an independently earned award, a customer-voted result or proof that the company outperforms every local provider.
Local firms replace cross-market copying
International pages do not reuse Türkiye-based individual experts as substitutes for local market research. Each market includes locally relevant SEO firms identified through public directories or official pages. Where a microstate has few providers, an adjacent-market firm may be used only when its regional role is made clear.
A shortlist is a starting point
Position reflects editorial presentation within this publication. It does not establish universal superiority. Search performance depends on scope, implementation access, technical condition, competition, content resources, budget and time. No listing should be read as a fixed ranking guarantee.
Evidence can change the record
Requests concerning a factual error, outdated detail, source problem, attribution issue or rights concern are reviewed on evidence. Provide the affected URL, the exact statement, the requested correction and a reliable source.
