Does google scrape links from PDF files? do these links pass link juice?
-
Title is pretty much the whole question.
-
I made a test and it seems that yes, the links from pdf count for ranking.
The test is on my Romanian blog http://seogan.ro/link-building-pdf-urile-o-sursa-de-linkuri-test
You can find an English translation here: http://www.seogan.com/pdf-link-building
Hope it helps.

Yes it does according to Google tech spec http://code.google.com/apis/searchappliance/documentation/50/admin_crawl/Introduction.html
which specifically states if follows html links in pdf 'It follows HTML links in PDF files, Word documents, and Shockwave documents'. Google's own api docs carry more weight than a comment in a forum_._ If they are licencing this out as an application it would suggest that the same technology is available in the main engine as does Dunamis's comment about a listing in a pdf document being found in search results.
You can test for youself by publishing a pdf with a link to a info page that does not show up in any other links. Include the pdf in your sitemap but not the test page and check if it shows in googles index site:yoursite.com the next time it crawls.
This also gives some insight in an interview with Matt Cutts - http://www.stonetemple.com/articles/interview-matt-cutts-012510.shtml
Eric Enge: What about PDF files?
Matt Cutts: We absolutely do process PDF files. I am not going to talk about whether links in PDF files pass PageRank. But, a good way to think about PDFs is that they are kind of like Flash in that they aren't a file format that's inherent and native to the web, but they can be very useful. In the same way that we try to find useful content within a Flash file, we try to find the useful content within a PDF file. At the same time, users don't always like being sent to a PDF. If you can make your content in a Web-Native format, such as pure HTML, that's often a little more useful to users than just a pure PDF file.

Google definitely does index the contents of pdf files. I found this out the hard way as I had a real estate pdf on my site that I wanted to have listed in the index, but I didn't know that the contents would be crawled. The pdf contained some listings that I was not legally allowed to advertise on my site. (It was legal for me to give someone a report with the listings in it though).
When another realtor was searching for their own listing, my pdf came up. I got in trouble. I'm ok now though.

Have a look at this article http://searchenginewatch.com/article/2067225/Google-Does-PDF-Other-Changes it explains some of the doc library search for pdf files and Google's statement here http://googleblog.blogspot.com/2008/10/picture-of-thousand-words.html.

How long does it take Google to remove links after using disavow tool?
Hi guys, So we're currently in the process of removing some of the less useful and more suspect links from our profile, and used the Google disavow tool to do so. We uploaded the .txt file to the search console on 7th July this year, 2 months ago now, and according to our most recent site crawl, the suspect links are still showing up on our link profile. Do we have any idea how long this is roughly supposed to take? The ideas I've found online are conflicting - anything from 3-4 weeks to 6-9 months. Which is it? Is there any way of fast-tracking this process? Thanks!

How much time does it takes for a backlink to get registered in Google? My basketball anime website has been live since start of this week and Google has not registered any backlink.
So my website https://www.animedhfa.com/basketball-anime/ about basketball Anime has shown no changes in DA or backlinks. It has been 5 days perhaps since it went live.

Footer Links And Link Juice
I'm starting to learn about link juice and notice in GWMT > Traffic > Internal Links, that the list is in this order by the links counted on each page. Some are in the footer and some are in the header, with some being more important than others commercially i.e. /register /privacy /terms /search /sitemap /disclaimer /blog /register So I am wondering if I should add a 'no-follow' attribute to the footer links i.e. privacy, terms, disclaimer and leave the others as they are? Does this help retain link juice on each page where the links appear? Or am I missing the point all together? This is my website: http://goo.gl/CN0e5

A link with "return false"- OSE sees as a No Followed Link
Hello, I couldn't find a clear answer to the impact on SEO for a link written in this way: [" class="expert_info" onclick="window.open(this.href);return false;">](w</span>ww.yourwebsite.com<span style=) [Does the "return false" act as a "no follow"? I came across this in our link data in Open Site Explorer which lists these links all as "no follows." However, an engineer I spoke to said that it shouldn't impact search engine behavior. Any ideas? Thank you in advance! -Sarah K.](w</span>ww.yourwebsite.com<span style=)

Etsy.com --Getting link juice through other pages on search results?
My sister has a store page on etsy.com where she sells home made crafts. And I want to help her rank higher on google with some of the other etsy stores. So i started to look at the other etsy store pages that are ranking well on google and found that they have a page authority between 48 to 52. So i looked at the backlinks of the ones ranking well on google with high page authority and found that many of their best links came from the internal search results page on etsy.com, and some only had one link from just an arbitrary etsy.com search page. I'm thinking this is because another product being listed on the seach page has a high page authority which then passes some of its link juice onto every other product on the page. But what is interesting is products are always being sold or getting added so even though you are on a search results page that happens to benifit from the link juice of another product the next time the page gets crawled you will be on a different search page. So i am thinking in order to maintain high page authority to you just have to have a lot of products listed so that there is a greater likely hood that you will find yourself on the same search page as another high authority page. I have not been doing SEO very long so i would love to hear what others think. I really have no idea, am i on the right track with this? (edited post) Thanks
