For example, if your ad group has a number of keywords about lilies and tulips, we try to find pages about these two topics together. If you have an ad group with diverse keywords on different themes, it may decrease the number of pages on which your ad is likely to appear.
And here:
[adwords.google.com...]
The AdWords system will identify a variety of themes in the keyword list, including pajamas, video games, and the movie 'Star Wars.' As a result, the system may show the ads in this ad group on content pages relating to all these themes. For example, an ad for Matrix pajamas could show on a Star Wars fan site.
These two explanations seem to contradict each other.
Could you please let us know which is the correct one?
Does the system only display ads on pages that contain all themes of all keywords in the ad group, or does it display ads on all pages that contain any of the theme of the keywords?
That's a huge difference.
Thanks.
the first explanation is about the reduced frequency of your ads appearing.
in the example given, you might do better to have one ad group for tulips and another for lilies.
then your tulips ads show up on "tulips" pages as well as "tulips and lilies" pages.
the second explanation regards the poor placement of ads.
(the way it is stated it seems like showings ads for matrix products on a star wars site is a good thing but i think the intended otherwise.)
if i was doing that set of movie merch i would have one campaign for movies and another for merch.
the movie campaign would have a "matrix" ad group, a "star wars" ad group, etc.
the merch campaign would have a "pajamas" ad group, a "gamecube" ad group, etc
it's really describing two different types of bad effects from a diverse set of keyword themes
Right. But the descriptions of how the system matches keywords to pages seem to contradict each other.
we look for pages that match most of the keywords in your ad group
the system may show the ads in this ad group on content pages relating to all these themes
"most" or "all" - not that contradictory...
