Odd backlinks from yahoo news
-
Can anyone explain what this backlink does? The original content was syndicated on Yahoo News from Mashable. At first glance it appears to be a straight up follow link from Yahoo to Mashable, but upon closer inspection I saw this in the code.
went public just three months ago
Here's the article on yahoo news: http://news.yahoo.com/facebook-zynga-generates-12-revenue-them-175509319.html
I've rarely seen backlinks from yahoo for any content partner let alone follow links. The us.lrd.yahoo.com in the hyperlink makes me highly suspicious.

Thanks Michael! That was quite insightful : )

Hey Mike Fan,
What you're looking at there is called a data reference link (that ylt= attribute gives it away). In short, it is indeed a followed link and would pass any authority you'd expect from a plain old link. The big difference is in how it's used.
The _ylt type variables are data packets. They contain specific base64 encoded data. The link could be a login, referential data, tracking data, or even spyware. The main point is someone making that link wants to keep track of who's doing what with it. On large sites, it's actually more common than you'd think for tracking purposes.
In short, this link is probably fine, even if it's a little scary looking in the page source. When a site that famously no=follows uses a followed link, you better believe they're going to track what's going on when they do.
Mike

Domain Three (will redirect to Domain One) - has quality backlinks When the new website is launched on Domain One I will contact the backlink providers and request they update their URL - i assume that would be the best.0 -
Help: domain name change and Google News
Hi. I work for a regional news source, and our (separate) Spanish-language news publication recently changed its domain name. The publication lost its Google News inclusion. Most of their traffic came from Google News, so traffic tanked. They're trying to get back in. They reapplied but didn't get approved. They're now in the 30-day waiting period to reapply again. The website is run by a third-party company, which handled the domain name change in April (2015). That company has been running their site for a couple of years. Our in-house devs' hands are tied on helping, because we (at the mother company) don't manage their site. This third party has not been responsive. The Spanish pub folks have reached out to me to help them prepare for Round 2 of reapplication. I'm the mothership in-house SEO, but I've never experienced this situation before. Because everything seems to be in order besides the ham-handed changes, my best advice to them so far is: You'll have to wait until Google gets to know you again, unfortunately. Does that sound right? Any pointers out there for bringing their best possible A-game to the next round?

What is the best way to refresh a webpage of a news site, SEO wise?
Hello all, we have a client which is a sports website. In fact it is a veyr big website and has a huge number of news per day. This is mostly the reason why it refreshes some of its pages with news list every 420 seconds. We currently use meta refresh. I have read here and elsewhere that meta refreshes should be avoided. But we don't do it to send to another page and pass any kind of page authority / juice. Is in this case javascript refresh better? Is there any other better way. What do you think & suggest? Thank you!

Site not ranking in Google but comes up #1 in Yahoo and Bing
Hi everyone, I've been working on SEO for this site for about 2 years and for some reason the site has just tanked in google. However it shows up #1 in yahoo and bing for the same search. http://www.nfsmn.com Phrase: "commercial foundation repair mn" If anyone can shed some light on the issue I would really appreciate it. They do have a sister-site: american-waterworks.com that may be causing issues as they link a lot of content to amww but not the other way around. Thanks Eric

Do Backlinks to a PDF help with overall authority/link juice for the rest of the domain?
We are working on a website that has some high-quality industry articles available on their website. For each article, there is an abstract with a link to the PDF which is hosted on the domain. We have found in Analytics that a lot of sites link directly to the PDF and not the webpage that has the abstract of the article. Can we get any benefit from a direct PDF link? Or do we need to modify our strategy?

DISQUS COMMENTS backlinks-good for seo? YES/NO?
DISQUS COMMENTS backlinks-good for seo? YES/NO? I have just started commenting on "powered by disquus" websites in the Disqus comments box and left a link to my website in the name field! Having googled whether Disqus comments backlinks are any good for seo purposes i have discovered that there is a 50/50 view on the subject with some people saying they are a "goldmine" for getting high PR backlinks and others saying they are a waste of time because googlebot cannot read Java. My own experience of commenting on Disqus powered websites is that wordpress blogs powered by disqus comments ARE INDEXED by GOOGLE and the "BACKLINK IS IN THE SOURCE OF THE PAGE" When i comment on normal websites using the Disqus comment system i have found that my Disqus comments ARE NOT indexed by Google and there IS NO BACKLINK in the page source! Has anybody got any views on whether Disqus comments backlinks are any good?
