Novelty wears off. Even if people aren’t getting sick of your ads, your product itself will become less revolutionary over time. When Casper launched, a direct-to-customer mattress-in-a-box company was a hot new take on the traditional sleep industry. Now there are so many competitors that the idea of a mattress showing up at your door in a box just isn’t as exciting.
To do this, I often align the launch of my content with a couple of guest posts on relevant websites to drive a load of relevant traffic to it, as well as some relevant links. This has a knock-on effect toward the organic amplification of the content and means that you at least have something to show for the content (in terms of ROI) if it doesn't do as well as you expect organically.
I feel we can also focus a lot on the kind of keywords we target. I had a client who was in a very competitive market place, we optimized their site for some really targeted, long tailed keywords which didn’t have very high search volume, so the traffic didn’t really go up drastically but the amount of conversions & the kind of CTRs the site received was incredible.
In March 2006, KinderStart filed a lawsuit against Google over search engine rankings. KinderStart's website was removed from Google's index prior to the lawsuit and the amount of traffic to the site dropped by 70%. On March 16, 2007 the United States District Court for the Northern District of California (San Jose Division) dismissed KinderStart's complaint without leave to amend, and partially granted Google's motion for Rule 11 sanctions against KinderStart's attorney, requiring him to pay part of Google's legal expenses.
Though a long break is never suggested, there are times that money can be shifted and put towards other resources for a short time. A good example would be an online retailer. In the couple of weeks leading up to the Christmas holidays, you are unlikely to get more organic placement than you already have. Besides, the window of opportunity for shipping gifts to arrive before Christmas is ending, and you are heading into a slow season.
