Ranked by estimated web presence, not by measured traffic or by any assessment of the businesses themselves. The change column is movement within this ranking since October 2025, recalculated for every month on record. Sites measured in fewer than two months show a dash rather than a change. How this is calculated.

Rankings draw on Chrome traffic data (the Chrome UX Report, © Google, licensed CC BY 4.0) and registered company data used with permission from companycheck.ie. It is not a measure of revenue or of the quality of the business. How this ranking is calculated.
