The existing content may speak to core audiences, but it isn’t producing many strong organic results. For example, the content header Capitalizing on the Right Skills at the Right Time With Business Agility may seem OK, but it doesn’t include a keyword phrase within striking distance. The lengthy URL doesn’t help matters. Extraneous words prevent any focus and the URL is bogged down by “business” and “agility” duplication:
One common scam is the creation of "shadow" domains that funnel users to a site by using deceptive redirects. These shadow domains often will be owned by the SEO who claims to be working on a client's behalf. However, if the relationship sours, the SEO may point the domain to a different site, or even to a competitor's domain. If that happens, the client has paid to develop a competing site owned entirely by the SEO.
Over the past few days or so, I have been seeing chatter both at WebmasterWorld and Black Hat World around ranking and traffic changes related to Google organic search. I got to say, I doubt Google pushed anything specific this week or even next week. Rankings do change by itself and new content is always being added to the index but an algorithm update - I doubt it.
