Regarding the two hypotheses being kicked around - connector words and older results - both would be consistent with my lack of change in traffic. My rankings have not changed much in the last six months, though I was expecting some changes recently. My most common connector word (of) is included in my titles.
Can anyone provide counter-evidence for either of these hypotheses? For example, is there anyone who has lost traffic whose traffic had not changed much (until now) in the last six months?
