Do site-wide links help?
Posted by multippt
When it comes to links, it is known that the more links there are, the merrier. What about site-wide links? All it takes is to add a link to every page, and you’ll get plenty of links. Site-wide links comes in all flavors: External ones, internal ones. Internal site-wide links are easy: put a link to your main page on every other page, and presto, a site-wide link. Depending on the size of the site, you can get several links, to hundreds.
Do they really help?
They may help. PageRank is one visible proof. But, each of those links appear to weigh lesser than several links scattered about. Sure, you have hundreds of links that can compensate for that, but it’s worth noting that even internal pages with the most exposure to site-wide links (e.g. archives in blogs) get a much lower PageRank than other pages that are linked less often (e.g. tag pages). Strange behavior?
On the other hand, site-wide links do add on to PageRank, but at the same time reduce PageRank (for the pages with the link). So, having many site-wide links on a site will result it in having more pages getting the juice, but it also results more pages having the same PageRank.
External Site-wide links?
Site-wide external links give a varying amount of link juice. If they are one-way ones, they pack a punch, unlike reciprocal ones that do not influence much. However, save your links, it’s probably much better to get several links from a site than getting site-wide links.
Another problem newly introduced by Google regarding external links, is that Google is weakening their strength, and penalizing certain links (usually site-wide ones) that it would consider “paid” or “sponsored”.
Weakened site-wide links?
Strangely, Google treats sitewide links unpredictably. Sometimes it credits them (particularly in pages you least expect them), sometimes it doesn’t. There is also a problem of links that come from only 1 site. Which is better? 1000 links from different sites, or 1000 links from one site? Google probably credits the former more than the latter in terms of PageRank.
Outbound links in a page
Within this site itself lies pages with varying PageRank. The main index page has most of the external links, so all other internal pages would have to get their link juice from the main page. Categories pages for example, have much lesser PageRank compared to some lesser tag pages, even though they appear almost everywhere in the site.
RSS pages on the other hand appears to get the most benefit out of PageRank. Seems like they are trapping the PageRank. After all, the amount of PageRank is determined by the amount of back-links and outgoing links (RSS feeds have much fewer than any other pages). The more back-links you have, and the fewer outgoing links you have, you get a page with a high PageRank. Quite a nice theory ain’t it?

On any case, it’s up to the webmaster to control who shall and how to link to their site.
