Tilføje keywords i footer

Hejsa

Jeg ser ofte websites hvor der er tilføjet en håndfuld keywords i bunden af siden.
Noget i denne stil:

keywords: tracker, website tracker, website monitoring services, web site monitor, web site monitoring service, server monitoring, website monitoring, website uptime, alert when host is down, web site monitoring down, free server monitoring, website availability, server monitor, check web page, website performance, server uptime, uptime alert service, downtime, uptime, monitoring, downtime alert, server monitoring sms alerts, check site uptime, monitor web site uptime, site uptime, web server monitoring, web site performance monitor, website monitoring service, web page monitoring, site availability, site monitoring, remote server monitor, uptime tracking, monitoring services sms, site uptime monitoring, monitoring websites free, measure downtime, check server uptime, external server monitoring


spørgsmålet er så om det har nogen effekt og hvor småt det må stå?
