Rank Checking
The relative importance of checking rankings is debatable. In fact, it was at @SEMpdx SearchFest industry conference where I heard my first full-blown rant from @ConradSaam about the uselessness of checking rank (he recommended focusing on traffic and conversions) – that was 4 years ago and before the Google Hummingbird algorithm update and before Google started rewriting queries based on perceived user intent. I’ve used and still use rank checkers, but the effectiveness of SEO strategies based on keyword ranking really seems to be dying if not already dead. That said, here’s some tools I’ve used:
Rank Checker for Firefox
This light and easy desktop tool checks rankings with the click of a button. Quick, easy and free.
