The same phrase in many different pages of one site

[webg]

Hi,
Recently, I had to add the same phrase, with 15 words, nearly, in 700 posts in a same blog. In this phrase is written about the site ownership and eventually some links showing the posts sources.

I thought in create a image, but it will be some variations in the source words (2 or 3), therefore I chose to use text format.

I'd like to read some comments and opinions about this kind of insertion (the same phrase in many different pages of one site). For exemple, did you handle this in your site? Problems or benefits (mainly with indexing)?  Special code to indicate in this case? Any threat?

I add one sentence equal in every one of the 700 post (700 pages/urls). At the end of every article

It's a signature in the text: "Content created by the group of portal XXX with informations of YYY."

XXX = name of the site of the cliente and

YYY = name of the site where the information has been used (source). In yyy will be puted a external link.

One phrase (or one sentence essentially) inserted randomly into the content of blog pages with 700 words in each article? No problem there.

But i would not hyperlink in that same sentence and would not use the same anchor text. I would greatly diversify the anchor texts and URLs you are pointing to and insert then once or twice maximum in random places in the 700 word articles.
