Today I have noticed that Google is listing the keywords OptikPointfrom 918, which is the regular index listing "or is it?" and then jumped overnight to 12,400, then back to 918, and then to 10,600 for results on Google.com Is there a SERP update going on or am I just seeing things?
Yes, and update is going on. Just like every minute of the day. Jumps could be easily explained by hitting different datacentres on different requests.
