Embedding PDF previews and maintaining crawlability/link-equity.
-
One site that I'm working on has previously had a great deal of success from the pdf preview content on the site. The pdf previews are quite substantial and rank for many many long-tail terms that drive a reasonable amount of traffic back to the site to purchase the full version of the product.
As part of a site redesign, the way the pdf previews are embedded/presented on the page is changing slightly:
The proposed modal pop-up on the new site the code looks like thie:
<object data="my-pdf-preview.pdf" type="application/pdf" style="width:100%; min-height:600px; max-height:100%;max-height:100%;"><embed src="my-pdf-preview.pdf" type="application/pdf"></object>
Where as the old code looked like this:
<object data="mt-pdf-previewpreview.pdf#view=FitH,50&scrollbar=1&toolbar=0&statusbar=0&messages=0&navpanes=0" <br="">type='application/pdf'
width='100%'
height='600'>It appears your Web browser is not configured to display PDF files.
No worries, you can download the PDF file here.</object>
Note: how previously the code contained a plain, standard link to the pdf document.
My worry is that without this link, search engines won't a) be able to discover/crawl the pdf content or b) pass any link-equity to these pdfs.
Does anyone have any experience/recommendations about this? I'd like to have some information before I request that they add a plain link to the pdf previews back onto the on-page content.

That's the route I'd push for as well I think.
Agreed on experimentation. Please report back if you get a chance to test this. Perhaps choose a small number of PDFs on this site redesign and leave the link off of them?

Thanks Kane - I've managed to make the case for a real-simple "download preview pdf" link so at least I feel comfortable that they won't lose too much of this "hidden" traffic.
It would still be nice to understand how <embed> is handled and whether any link-equity passes though the embed. Tight deadlines on projects don't mean you have time to experiment.

I haven't seen any studies with <embed> the way I have with <iframe>. <embed> is also used for video and flash, but neither would be indexed the same way as PDF so hard to compare. The embed tag is pretty standardized, so I really doubt they wouldn't crawl this similarly.</p> <p>IIRC in the ugly era of flash, it was proper to have a <noscript> {crawlable content here} </noscript> section after the <embed>, so that's one comparable situation, but that's due to the flash itself not being crawled well.</p> <p>If it's not a hassle, I would add the text link to the PDF that says "download full PDF" or similar. If it is a hassle and takes longer than a couple hours, then it's a harder call.</p> <p>Similar thread that could be helpful:</p> <ul> <li><a href="http://stackoverflow.com/questions/3686331/does-google-index-html-content-supplied-by-the-object-tag">http://stackoverflow.com/questions/3686331/does-google-index-html-content-supplied-by-the-object-tag</a></li> </ul></iframe>

Search engines will still be able to crawl the PDF. They crawl images, don't they?

Ogranization Schema/Microformat for a content/brand website | Travel
Hi, One of our clients have a website specific to a place, for eg. California Tourism in which they publish local information related to tourism, blogs & other useful content. I want to understand how useful is to publish Organization Schema on such website mentioning the actual Organization, which in this case is a Travel Agency? Or any other schema would fit in for such websites?

Does Navigation Bar have an effect on the link juice and the number of internal links?
Hi Moz community, I am getting the "Avoid Too Many Internal Links" error from Moz for most of my pages and Google declared the max number as 100 internal links. However, most of my pages can't have internal links less than 100, since it is a commercial website and there are many categories that I have to show to my visitors by using the drop down navigation bar. Without counting the links in the navigation bar, the number of internal links is below 100. I am wondering if the navigation bar links affect the link juice and counted as internal links by Google. The Same question also applies to the links in the footer. Additionally, how about the products? I have hundreds of products in the category pages and even though I use pagination I still have many links in the category pages (probably more than 100 without even counting the navigation bar links). Does Google count the product links as internal links and how about the effect on the link juice? Here is the website if you want to take a look: http://www.goldstore.com.tr Thank you for your answers.

Link Brokers Yes or No?
We have a client who has asked us to talk to link brokers to speed up the back linking process. Although I've been aware of them for ages I have never openly discussed the possible use of 'buying' links or engaging in that part of the industry. Do they have a place in SEO and if so what is the MOZ communities thoughts?

Wrong titles in site links
Hello fellow marketers, I have found this weird thing with our website in the organic results. The sitelinks in the SERP shows wrong written text. As in grammatically incorrect text. My question is where does Google get the text from? It is not the page title as we can see it. kKsFv0X.png

Increasing Internal Links But Avoiding a Link Farm
I'm looking to create a page about Widgets and all of the more specific names for Widgets we sell: ABC Brand Widgets, XYZ Brand Widgets, Big Widgets, Small Widgets, Green Widgets, Blue Widgets, etc. I'd like my Widget page to give a brief explanation about each kind of Widget with a link deeper into my site that gives more detail and allows you to purchase. The problem is I have a lot of Widgets and this could get messy: ABC Green Widgets, Small XYZ Widgets, many combinations. I can see my Widget page teetering on being a link farm if I start throwing in all of these combos. So where should I stop? How much do I do? I've read more than 100 links on a page being considered a link farm, is that a hardline number or a general guideline?
