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?

SEO Strategy - Content/Outreach/Links
Hi everyone I'm trying to prioritise my tasks for 2018 & wondered if anyone had any useful templates they use? In terms of SEO tasks, my priority was going to be content/outreach/links - Focusing on user guides/blogs onsite Then outreach articles/some PR that doesn't go against Google guidelines offsite. My struggle with the onsite content/blogs we produce is we have no real social media plan/manager so my content outreach always seems hampered by this. I've tried taking on some of the social stuff, but this ends up being too much for just me to do. I wondered if there were any other SEOs who face this issue and who have found some good solutions? I'm stuck in a bit of a rut and can't seem to effectively push forward with outreach/content writing. Thank you Becky

Value of no-follow links
I'm curious to understand roughly how much % of value a no-follow link has in building authority relative to a do-follow link? I understand that Google seems consistently and growingly focused on value - ie. is the link valuable in growing the business, irregardless of SEO - and perhaps therefore the no-follow / do-follow distinction is becoming a more unnecessary dichotomy. How does Google look at do-follow vs no-follow links? And how much weight now is really given to one compared to the other?

Links on page
Hi I have a web page which lists about 50-60 products which links out to either a pdf on the product or the main manufacturers website page containing product detail. The site in non e-commerce is this the site/page likely to get hit by Penguin? Would it be best to create a separate page for the product/manufacturer group i.e 5 or 6 pages but linking out to the PDFs etc...?

Link building - still effective ?
Hi, I know 70-80% of the links on Google have no-follow keyword. What I need to know is if link building by using guest posting and a combination of no-follow links through social media is still effective ? What would you suggest in terms of link building. I have read all the articles on moz and everything, but I need a personal touch on this matter. Thanks,

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

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.

Internal Javascript Links
Hi, We have a client who has internal links pointing to some relatively new pages that we asked them to implement. The problem is that instead of using standard HTML links, their developers have used javascript - e.g. javascript:GoTo... The new pages have links from the homepage (among others) and have been live for about 3-4 weeks now - yet are still to be indexed by Google, Bing & Yahoo. Is it possibe that Javascript links are making them difficult to be found? Thanks in advance for any tips.
