      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

          p.s. always useful for chaning your mindset about a lot of things isn't it.

            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.

                    Does using data-href="" work more effectively than href="" rel="nofollow"?

                    I've been looking at some bigger enterprise sites and noticed some of them used HTML like this: <a <="" span="">data-href="http://www.otherodmain.com/" class="nofollow" rel="nofollow" target="_blank"></a> <a <="" span="">Instead of a regular href="" Does using data-href and some javascript help with shaping internal links, rather than just using a strict nofollow?</a>

                    301 with nofollow ?

                    Hi, our ecommerce link penalty was revoked by google back in Feb 26th 2013, but to this day we have not seen any improvement on our rankings. Due to 80% revenue loss we had to layoff quite a few people to stay alive. Situation now is more dire then ever for our company. We have millions of dollars invested in our business and google just busted it for some "low quality" or "spammy links" as they call it. We want to try to move to a different domain and do a 301 from the old domain to make sure our previous customers can still find us as a last effort to stay alive. But doing so we do not want to the bad links juice to flow to our new domain. Can we do a 301 with nofollow and will that have any negative impact or any impact at all.? any suggestion is greatly appreciated. Thank you Nick We are planning on moving to a different domain after 10 years, and laying off bunch of people due to loss of revenue.

                    Dofollow and Nofollow links

                    What is the difference between dofollow and nofollow links? I know that some sites/blogs only let you post nofollow links. In such a case how do I know if a comment I posted on a certain site will be a nofollow or dofollow? How about big traffic sites such as Huff Post. Do they only allow nofollow links?

                    NoIndex/NoFollow pages showing up when doing a Google search using "Site:" parameter

                    We recently launched a beta version of our new website in a subdomain of our existing site. The existing site is www.fonts.com with the beta living at new.fonts.com. We do not want Google to crawl the new site until it's out of beta so we have added the following on all pages: However, one of our team members noticed that google is displaying results from new.fonts.com when doing an "site:new.fonts.com" search (see attached screenshot). Is it possible that Google is indexing the content despite the noindex, nofollow tags? We have double checked the syntax and it seems correct except the trailing "/". I know Google still crawls noindexed pages, however, the fact that they're showing up in search results using the site search syntax is unsettling. Any thoughts would be appreciated! DyWRP.png

                    Meta tag "noindex,nofollow" by accident

                    Hi, 3 weeks ago I wanted to release a new website (made in WordPress), so I neatly created 301 redirects for all files and folders of my old html website and transferred the WordPress site into the index folder. Job well done I thought, but after a few days, my site suddenly disappeared from google. I read in other Q&A's that this could happen so I waited a little longer till I finally saw today that there was a meta robots added on every page with "noindex, nofollow". For some reason, the WordPress setting "I want to forbid search engines, but allow normal visitors to my website" was selected, although I never even opened that section called "Privacy". So my question is, will this have a negative impact on my pagerank afterwards? Thanks, Sven

                    Hi!! Another noob question: Should I be nofollowing my site's cart and checkout pages? Or as SEs can't get to the checkout pages without either logging in or completing the form is it something I shouldn't worry about? Have read things saying both. Not sure which is correct. Thank you! Appreciate the help. Lynn
