Doubleclick and NoFollow
-
Hi,
I'm trying to work out whether a group of links to my site are Follow or NoFollow.
There is no rel=noFollow on the link but they do appear to go through Doubleclick (the link begins with this http://googleads.g.doubleclick.net/), will this automatically cut-off any link juice?
Thanks.

Hey Jarno,
Thanks for your detailed response. I will look into the calculations as a method.
I also think doubleclicks policy is completely nofollow, I was just looking for some confirmation.
Thanks.

Ross,
it depends on the DoubleClick policy which I believe is completely nofollow.
As an additional explanation to Alan's statement:
Normally about 85% of a page's value can flow to another page on another website. If that links points to another page again only 85% of that can pull through, so theoretical:
Lets say website A has a value of 5 and link to website C through DoubleClick (B)
Hop 1: Value a * 85% = 4.25 juice flow
Hop 2: Value B * 85% = 3.61 juice flow
And that is if there is only 1 link on the page. A long long time ago when PR was everything I read an article on how to calculate PR for page x and it goes as follows:
PRx = ((1-0,15) * PRpage)/#links
So in this case is you wanted to calculate the recieved PR for page X that it got from the link on page Y (with a PR of 5 and a total of 25 links on the page) you would get:
PRx = (1-0,15)*5)/25 = 0.17
All these calculations for Page x together give you a number and that number equals a scale which in turns decides what PR wold be given to a specific page.
I personally still calculate a lot of my incoming flow like this only by now I don't focus on PR but more on authority.
Hope this will help you.
regards
Jarno

ah now I follow. (no pun intended)
The links were placed there by request and I am sure the website wouldn't purposely noFollow the links because, as you say, they would gain nothing. But they go through doubleclick, which usually suggests a sponsored or paid ads. Obviously sponsored or paid ads should be NoFollow but these links aren't paid advertorials, they are natural links. So I just wanted to know whether something going through DoubleClick automatically kills any juice.

All links use up link juice. By no following a link, you do not save any link juice, you just don't pass it to the linked page. So the website owner has nothing to gain by no following you. The most common use of no-follow these days is to discourage spammers placing links in comments and forums.
did you place the links there? then it may be that the owner of the site will no follow you, Did he pace them there, then he has nothing to gain by no-following you.

Hi Alan,
Thanks for responding.
I don't really understand your answer (Sorry!). Could you elaborate a little?
Thanks

I have no knowledge of doubleclick, but the page will be leaking link juice thought al those links no matter what he does., so there would be nothing to gain from the website owner by no-following you.

"nofollow" vs. "no follow"
Does anyone know if it is problematic to have a space between the "no" and the "follow"? I just discovered our CMS has been inserting a space and am trying to understand if it the reason why something that we were trying to keep from being indexed has become indexed.

Should internal links in my table of contents be tagged as nofollow?
Hi All, I have the LuckyWP Table of Contents plugin installed. I recently noticed that you can tag your internal links with and nofollow. I understand that it's always a good idea to link internally and to pass link juice to my own content. But with detailed posts that have over 20 headings, I'm thinking that internal linking for headings may actually hurt me because it takes my links well above 100. Any ideas what the best practises are in this scenario? Thanks.

'External nofollow' in a robots meta tag? (advertorial links)
I believe this has never worked? It'd be an easy way of preventing any penalties from Google's recent crackdown on paid links via advertorials. When it's not possible to nofollow each external link individually, what are people doing? Nofollowing and/or noindexing the whole page?

The difference between an noindex and nofollow?
What is really the difference between an noindex and nofollow and why/when do you want to use them? Built my first wordpress site and the blog "posts" that make up my home page confuse me....as far as passing link juice to my home url...not sure what I am asking here! How do I use nofollow/noindex or is the issue I should be looking at is 301/canonical. Or neither?

Nofollow links appear to be still included in SEOMOZ crawl and Google
I have added the nofollow tag to links throughout my site to hide duplicate content from Google but these pages are still being shown in my SEOMOZ crawl. I also fetched an example page with the Googlebot within Webmaster tools and it showed all nofollow links. An example is http://www.adventurepeaks.com/news All News tags have nofollow but each tag is appearing in my SEOMOZ crawl report as duplicate content. Any suggestions on whether this is a problem or if i have applied the tag incorrectly? Many thanks in advance

Noindex, nofollow on a blog since 2009
Just reviewed a WordPress blog that was launched in 2009 but somehow the privacy setting was to not index it, so all this time there's been a noindex, nofollow meta tag in the header. The client couldn't figure out why masses of content wasn't showing up in search results. I've fixed the setting and assume Google will spider in short order; the blog is a subdirectory of their main site. My question is whether there is anything else I can or should do. Can Google recognize the age of the content, or that it once had a noindex meta tag? Will it "date" the blog as of today? Has the client lost out on untold benefits from the long history of content creation? I imagine that link juice from any backlinks to the blog will now flow back to the main site; think that's true? Just curious what others might think of this scenario and whether any other action is warranted.
