Our site was just crawled last night an we had a number of keywords fall 25% or so, from say # 30 to 38. What would cause such a drastic fall? We haven't taken down pages or changed changed page titles, url or content.
One thing we are having trouble with is our meta description and meta keywords for each page. Drupal 7 seems to be giving us trouble and the meta information isn't showing up anymore.
Would that cause the fall? Any other suggestions?
