For example, when you look up Jessica Alba and Alba Jessica, the trend is shown almost similar. However, when you look up Red Ball and Ball Red, there is no difference in trend to the eye. Similarly, for other such searches where the two trends are 'superimposed'. I'd like to know how accurate people thing this is; I mean why would Red Bull for example get the same amount of searches as Bull Red ? Does Google sometime only use one of these search volumes to predict the trend for both terms? This can be a very effective way of finding the right keywords for your niche and I always thought that is the case but this question was raised in my head seeing the similarities in trends of so many terms which can be transposed. What are the expert eyes in this tool's effectiveness in predicting the search trends accurately? Red Bull/ Bull Red: http://google.com/trends?q=red+bull,+bull+red&ctab=0&geo=all&date=all&sort=0 Furthermore, the difference in competition between the two terms is skyscrapping - one has 17m competititors, the other <100k.
It's obvious a persons name, where first last or last first will be searched more than a product name, trends shows unique data for the exact keyword phrase you entered. Google's own "accuracy" on what the search volumes are for their own system that they monitor behind the scenes unrestricted is on the dot.
I guess its a bug in google trends. any words with first and second letter exchanges shows same trends. i am sure one of the keyword receive less or more than the other.
