i have an almost similar question to ask. let's say, i have added 10 posts to 2 different categorys. the excerpts would be the same on both sites, which results in duplicate content. i'd like to customize my functions.php in a way, where i can choose, how the excerpts should be handled within the loop on a category basis. i've searched everywhere and found some great advice on that. only one extra option where i can't solve the problem is this: let's say, i use an excerpt containing the 55 first words in category 1, how can i use the second 55 words of the posts in category 2? i ask this, because it would be a big improvement on seo and could help others too.
i can't find a way to truncate the first 55 words, if i pull in 110. is there a more elegant way to solve that? thanks.
