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?

Looking for opinions on structuring meta title tags/page title/menu title/H1
Hi everyone I am hoping a few of you can share your opinions. I have been having conversations (okay, healthy debates) about how to write/structure meta title tag and how to compliment them with the H1, page title, menu name. To help explain the thought processes I will use a pretend keyword. How about "screwdriver". Case: (I made this up) we are redesigning a website for a construction tools manufacturing company (pretend name: ABC Tools) targeting OEMs who are interested in purchasing large quantities of tools. The product categories (to become main menu items) are Screwdrivers, Nails, Drills, and Hammers. (bear with me .... this is just an example I am making up on the fly) K. Circling back to screwdrivers - let's say we have one landing page (a primary category page and in the main menu) listing products and great details about screwdrivers. Focus keywords are screwdriver manufacturer, screwdriver supplier, construction screwdrivers Below are questions being debated. If you are willing ... how would you address these questions? And, can you explain WHY? QUESTION ONE: How would you structure the meta title tag (feel free to write one of your own) Screwdriver Manufacturer - Construction Screwdriver | ABC Tools ABC Tools - US-based Screwdriver Manufacturer Supplier Near You High-Quality Screwdrivers for Construction with ABC Tools QUESTION TWO: how would you write the H1 on the page? Would it match the meta tag? OR, would you write something different using the primary keyword? QUESTION THREE Remembering this is not a blog post ... it is a primary landing page linked to the main navigation. What would the menu title be? (remember the product categories above are how the main menu items are bucketed) Screwdrivers Screwdriver Manufacturer Typically in WordPress, the H1 and the menu title is auto-populated using the page title (not the title tag)... So, if we use Screwdrivers as the page title but we want the H1 to match the meta title tag, would we manually change the H1? Or, have the page title and title tag match, but manually change the menu item?

[Very Urgent] More 100 "/search/adult-site-keywords" Crawl errors under Search Console

PDF or HTML Page?
One of our sales team members has created a 25 page word document as a topical page. The plan was to make this into an html page with a table of contents. My thoughts were why not make it a pdf? Is there any con to using a PDF vs an html page? If the PDF was properly optimized would it perform just as well? The goal is to have folks click back to our products and hopefully by after reading about how they work.

PDF for link building - avoiding duplicate content
Hello, We've got an article that we're turning into a PDF. Both the article and the PDF will be on our site. This PDF is a good, thorough piece of content on how to choose a product. We're going to strip out all of the links to our in the article and create this PDF so that it will be good for people to reference and even print. Then we're going to do link building through outreach since people will find the article and PDF useful. My question is, how do I use rel="canonical" to make sure that the article and PDF aren't duplicate content? Thanks.

Where to link to HTML Sitemap?
After searching this morning and finding unclear answers I decided to ask my SEOmoz friends a few questions. Should you have an HTML sitemap? If so, where should you link to the HTML sitemap from? Should you use a noindex, follow tag? Thank you

Max # of Products / Links per Page on E-Commerce Site
We are getting ready to re-launch our e-commerce site and are trying to decide how many products to list per category page. Some of of our category pages have upwards of 100 products. While I'd love to list ALL the products on the root category page (to reduce hassle for customer, to index more products on a higher PR page), I'm a little worried about having it be too long, and containing too many on-page links. Would love some guidance on: Maximum number of internal links on a page If Google frowns on really long category pages Anything else I should be considering when making this decision Thanks for your input!

Are duplicate links on same page alright?
If I have a homepage with category links, is it alright for those category links to appear in the footer as well, or should you never have duplicate links on one page? Can you please give a reason why as well? Thanks!
