Did anyone experience a ranking drop in Bing & Yahoo lately for your key head terms? I saw our ranking drop from position #1 and #2 to around #8 and #9 for key head terms in Bing & Yahoo, but the same keywords rankings in Google remained stable at #1 or #2.
Rankings are always fluid. Some days you're up, some days you're down. If you're up all the time that means no competition. :)
In a world approaching 7 billion and several of those on the web with x millions getting into "internet biz" on either a yearly (or weekly!) basis, it's no surprise fluctuations will occur. This is not doom-saying, just merely a reminder each of us are not the only fish in the sea... and unless you are top predator there just might be another fish out there ready to gobble (google?) you up. :)
