I run a special news site and am trying to apply it to a little SEO sauce. One of the most important things is that to cover the duplication of content, I have covered all the fundamental topics but I am stuck with the order of content
as an example, the site's collection Sorted by date, view and rating. Since we do not have many news items, a collection page for a particular day is usually only a few items, so the following URL contains all the same content, although in different order:
- < Li> / News / Archive / 2010/05/16 /
- / News / Archive / 2010/05/16 /? O = view
- / news / archive / 2010/05 / 16 /? O = rating
Are search machines punish the repetition of this particular type of content? And if so, what is the best way to escape from the penalty? & lt; Link rel = "canonical" /> ? Tell Google; To enter the o parameter to the company? Marking sorted links with nofollow ? Only allow indexing of archived archive sites through robots.txt (not sure that this is possible)?
If you have a dynamic URL that is in standard format such as foo? Key1 = value & amp; Key2 = value2 We recommend that you leave the URL unchanged, and Google will determine which parameters can be removed
Basically, Google does not care about it Googlebot is smart enough to handle this problem for you.
I always use a legal tag, I feel cleaner.
