Welcome to the Q&A Forum

If I run a site that charges other companies for listing their products, running banner advertisements, white paper downloads, etc. does it make sense to "no follow" all of their links on my site? For example: they receive a profile page, product pages and are allowed to post press releases.  Should all of their links on these pages be "no follow"? It seems like a gray area to me because the explicit advertisements will definitely be "no followed" and they are not buying links, but buying exposure. However, I still don't know the common practice for links from other parts of their "package". Thanks

I currently have a campaign set-up that monitors a few competitors compared to our site. When I look at the Root Domain Metrics I see that Company A has 2,053 total external links, and Company B has 1,632 total external links. I wanted to view these links in more detail so I ran Advanced Inbound Links reports.  The reports returned 432 results for Company A and 693 results for Company B. Shouldn't these numbers match up with each other, or am I missing something? Also, I noticed that in the Inbound Links analysis for my competitors there are a number of results listed that are not actually inbound links, but are internal links from there own site. Is there a reason these are appearing? I am having problems because I am trying to use this campaign to show the improvements in our site vs our competitors.  However, OSE shows dramatically fewer total external links for our site (about 260 vs 3200 in Webmaster Tools) and I cannot tell if the competitor data is accurate? Thanks

I've searched extensively for this, but could not find a definitive answer. We recently updated our website and it contains links to about 30 PDF data sheets. I want to determine if the text from these PDFs is being archived by search engines. When I do this search http://bit.ly/rRYJPe  (google - site:www.gamma-sci.com and filetype:pdf) I can see that the PDF urls are getting indexed, but does that mean that their content is getting indexed? I have read in other posts/places that if you can copy text from a PDF and paste it that means Google can index the content.  When I try this with PDFs from our site I cannot copy text, but I was told that these PDFs were all created from Word docs, so they should be indexable, correct? Since WordPress has you upload PDFs like they are an image could this be causing the problem? Would it make sense to take the time and extract all of the PDF content to html? Thanks for any assistance, this has been driving me crazy.
