Do links in hosted documents help with domain authority?
-
When giving presentations in our industry, we often find that the PDF or PPT document is then hosted on the origination's domain for download by event attendees. If these files have links, do they count as inbound followed links?
-
Great answer. I've seen some old PDFs on some .gov and .edu domains, but unfortunately, there were no URL links.

If these files have links, do they count as inbound followed links?
Yes, absolutely.
You can find links from .ppt .pdf .xls .doc and many other types of document files in your Google Webmaster tools account.
In addition, those documents accumulate PageRank and pass it. I have some PR6 .pdf documents. You can also optimize their document properties so that they will compete in the SERPs with a title tag of your choice.
If you publish these types of files, always put an attribution link to your website and don't hesitate to link to content on your website where it would be useful to readers.
If you are clever you can even place "Add to Cart" buttons in these documents.
I got into a Panda problem because I had a lot of duplicate content in .pdf documents - to control the scale and appearance of printed graphics. I was able to use .htaccess to apply rel=canonical to the .pdf documents and attribute them to specific html pages.
These documents can do just about anything that a webpage can do if you are clever.

Backlinks and Domain Authority
Hi there, I have a question on backlinks. I have seen conflicting stories about it, and hoping someone with a vast amount of experience will be able to help me (If you could please be so kind). Now I understand the difference between 'no-follow' links and 'follow' links. I have accumulated quite a few 'no-follow' links through things like Facebook, Youtube, Twitter etc. I understand that they won't feed my site authority or trust; or anything of that sort (I do work on content too, and have gotten a few follow links, don't worry). Now I have seen conflicting answers to the actual importance of them. Some things I have read are saying that SEs completely ignore them (NFL), and they don't even consider them a 'link', but rather a user tool to further the experience of the reader on your site. Which is fair enough, but then people are turning around and also saying that Google relies heavily on them, and they only make up 5% of the internet or something. I have even read something saying they are the only ones worth getting (I know that is bs, but they must have a reason behind this thought?). If someone could enlighten me as to a 'ideal' ratio, and also any little known authoritative sites I could look at submitting content to. I am in the plumbing business, and doing my own sites, so I'm no expert. Also, what are the importance of comment links? I don't go for them, but don't know if I should? Sorry for the mouthful, but I would really appreciate help on this matter. Kindest regards, Kyle The Plumber Bro's The Electrician Bro's

Is it better to have a blog under your main website's domain or should the company's blog have its own domain?
Is it better to have a blog under your main website's domain or should the company's blog have its own domain? And if the blog is on its own domain, do links to the main site look good or bad to Google? Thanks! (And please feel free to add any other related advice you might have...)

Does the ratio of external nofollow links to external "do follow" links matter in terms of SERPs ranking?
My site has an external link nofollow:dofollow ratio of approximately 1:1 That is, there are about as many nofollow external links as "do follow" external links. I have an impression that the ratio of no-follow to "do follow" links is a factor in the way that our website shows up in SERPs. I have the impression from reading a variety of sources, and from looking at Seomoz, that calculate "trust" factors as if they mattered (in SERPs), that seem to value a relatively low nofollow:dofollow ratio. Am I correct about that? Thanks,

Do image links with no alt tags pass link value?
"... an image link with no alt tag is useless to search engines..." according to a Nov 2007 seomoz blog post. Is this still the case in 2011? I ask because I'm about to obtain a banner link on a high-traffic site (chiefly for the clickthrough value) but I notice the site uses neither "title" nor "alt" tags.
