Oftentimes mis-matched traffic is the result of an ambiguous search term. In any case, a high bounce rate for one term logically shouldn't affect your rankings and traffic for other terms.
Not even if it affects your site's overall bounce rate?
What if Google is using some semantic web analysis as part of this?
The fact is that there is some indication certainly from the terms that are appearing in my logs that there is some mechanism that Google has introduced that put my site in a place that gets traffic for long tail terms that I wouldn't target. This has resulted in spikes in bounce rate and a higher average bounce rate.
It seems to me to be logical that these long tail terms are appearing either because of a change in semantic indexing or Google search suggestions that are ajaxed in below the search field or a mixture of both.
It also seems perfectly logical that Google may be looking at overall bounce rate for a site in comparison with other sites in a broadish semantic topic area.
