Welcome to the Q&A Forum

Just an opinion..... Don't worry about PR.  Give them a followed link. If you nofollow the link you are sending these potential signals.... - this site paid me to link to them - I don't trust this site - this site could be spam So, if you nofollow the link why should any clean power flow back to you? I am not saying that the above is fact.  Just how I think about it.

You need to decide on a single URL structure to your website. http://www.mydomain.com/hello http://www.mydomain.com/hello/ http://mydomain.com/hello http://mydomain.com/hello/ The above four URLs could lead to the exact same page depending on how your site is set up. This would cause confusion for search engines. Which page do they index? Also, when someone links to your site, the links would split between the various URLs so your backlink power would be divided. The solution? Make a choice, then 301 or canonicalize your site based on that choice. If you decide you want the "www" version with the trailing slash, then the canonical code for your page would be: Adding this code lets search engines know which page to index and to consolidate your links to that page. With respect to your keywords, in general you wish each page to focus 1 or 2 keywords. I try to ensure they are used about 4 times on the page. If you see 33 keywords on a page you may be targeting too many words, or using them too often. It could also be that everything is just fine. It depends on a few factors.

Hi Marcos, Here's a response from the help desk regarding Juicy Link Finder (specifically regarding unicode characters) that I copied from http://www.seomoz.org/q/juicy-link-finder-doesn-t-support-hebrew-utf8-input. I'm asking the help team to come take a look at this thread and see if they have any more suggestions for your case, but this should help in the meantime. Keri Morgret, SEOmoz associate Hi Kevin I feel like I've got to be honest with you. It's an old tool and we're not very proud of it anymore. It doesn't take advantage of our awesome web index, or all the cool analysis we've done around powerful links. We're working instead to replace it with more powerful link tools. Our newer tools are built to support Unicode, but most of our older ones don't. Sorry about that! For example, I think you'd be much better off trying our Competitive Link Research Tool (it's in Labs and therefore sometimes gets overloaded, but it's so cool when it works!), or even running your competitors through Open Site Explorer. www.seomoz.org/labs/link-intersect www.opensiteexplorer.org The bottom line is that Juicy Link Finder is unstable and doesn't support Unicode (because we're deprecating it in favor of new technologies), and it doesn't give you very sophisticated results.
