Nofollow on site-wide banner links

[secubi]

Hi

I have a blog in relation to my webshop. On the blog I have two banners linking directly to the webshop on every page (site-wide links). Should I make the banner links nofollow?

Thanks,

Rasmus

Generally agree with the comments - links between two of your own sites shouldn't be a huge problem. Google could devalue them a bit, if they see the connection, but devalued isn't penalized. As Philipp said, if you also put contextual links to the webshop in the blog, it could be that the banners keep those links from counting - Google tends to disregard the 2nd, 3rd, etc. link to Page B from any given Page A. If the contextual links are specific, deep pages, though, you should still get value.

Thanks for your reply.

I am not worried that Google will see the banners as paid links. However, the blog is on a completly different domain with no relation to the webshop.

Instead of linking to the webshop's front page on every page on the blog, I would prefer to make some deep links to the webshop. I am worried that the value of these deep links will be reduced due to the banners.

As Phillip B states- there is no need to add nofollow. Are you worried that Google will see the banners as paid links?

Banner advertising is very common on the net, and does not cause penalties, so you need not worry. The fact that the banners are on your own domain (which i guess is on either a sub domain, directory or similar domain) means you are perfectly safe.

If you were paying for a site wide link, e.g footer, on a non related site then it may be a different case.

You may want to add your keyword as the image alt tag- SE's will see this as anchor text and imo this is almost as strong as a text anchor link

hmm, sorry i'd have to research this deeper and have gotta run soon...

actually i was thinking of those banners that have a js-link to an adserver, which then gets redirected. just packing the link in a javascript might actually not do the job (as google follows them now).

so i'm not even sure if javascript is the best way to "hide" these links in your case. be careful that you don't get in trouble for "cloaking" your links, that could have very adverse effects.

sorry for not being able to answer more specifically about the javascript:( 
hope someone with deeper knowledge can help you set this up!

Thank you very much for your reply.

Yes, I want to pass link juice via text links embedded in the blog posts (with an appropriate anchor text) when it is relevant - not via site-wide links.

Could you shown me an example on how to link the right way with javascript?

that doesn't seem necessary: since it's your own blog i assume you don't receive payment for it;)

nofollow won't do much for you in this case. but if you would like to assign more link power to possible text links from the content, you might want to consider redirecting the banner links via javascript. that way, no link juice will be wasted on banners that carry little seo value.
