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?

How Many Links to Disavow at Once When Link Profile is Very Spammy?
We are using link detox (Link Research Tools) to evaluate our domain for bad links. We ran a Domain-wide Link Detox Risk report. The reports showed a "High Domain DETOX RISK" with the following results: -42% (292) of backlinks with a high or above average detox risk
Intermediate & Advanced SEO | | Kingalan1
-8% (52) of backlinks with an average of below above average detox risk
-12% (81) of backlinks with a low or very low detox risk
-38% (264) of backlinks were reported as disavowed. This look like a pretty bad link profile. Additionally, more than 500 of the 689 backlinks are "404 Not Found", "403 Forbidden", "410 Gone", "503 Service Unavailable". Is it safe to disavow these? Could Google be penalizing us for them> I would like to disavow the bad links, however my concern is that there are so few good links that removing bad links will kill link juice and really damage our ranking and traffic. The site still ranks for terms that are not very competitive. We receive about 230 organic visits a week. Assuming we need to disavow about 292 links, would it be safer to disavow 25 per month while we are building new links so we do not radically shift the link profile all at once? Also, many of the bad links are 404 errors or page not found errors. Would it be OK to run a disavow of these all at once? Any risk to that? Would we be better just to build links and leave the bad links ups? Alternatively, would disavowing the bad links potentially help our traffic? It just seems risky because the overwhelming majority of links are bad.0 -
Phone number link / critical crawler issue
I've got 15 critical crawler issues coming up, all of which are ( tel: )links to the contact phone number. As this is a taxi firm, these links are pretty vital to customer conversion. Should I worry about these issues from an SEO perspective? If so, is there anything I can do about it?

Footer no follow links
Just interested to know when putting links at the foot of the site some people use no-follow tags. I'm thinking about internal pages and social networks. Is this still necessary or is it an old-fashioned idea?

How to rank for a location/country without having a physical address in that location/country
How do I go about it if my physical address (office) is in Country A but I want to rank my website in Country B, C and D (without having an office or physical address in the countries B, C and D)? I am aware of people setting up virtual offices in other countries/cities and adding them to Google Places/Maps with toll free phone numbers, but I don't wish to do any of that. I know Google will catch up with this one day or the other and punish me hard for trying to play games with it. Is there a way rank a website in another country without actually having a physical location there? If yes, please guide me how to go about it.

Multiple Internal links to same destinations
My company is redoing our homepage and there will be 4 links to our main play pages (5 games). 2 in the menu and 2 within the content. I was thinking I should no follow one of the links on the homepage + 1 in the menu so that we don't have link dilution from having multiple internal links to the same destination within 1 page. Does this make sense? Any downside of this or suggestions of a solution that may be more effective? Thanks!

URL Value: Menu Links vs Body Content Links
Hi All, I'm a little confused. I have read a number of articles from authority sites that give mixed signals over the importance of menu links vs body content links. It is suggested that whilst all menu links spread link juice equally, Google does not see them as favourably. Inserting a link within the body will add more link juice value to the desired page. Any thoughts would be appreciated. Thanks Mark

Finding broken links / resources by topic
Hi fellow mozzers! In an effort to ensure we're exploring every avenue when launching our new website, I was hoping to find some useful broken links / resources that we could incorporate into our link building. We have used the standard tools for this (W3C, Xenu etc), but they all seem to have the same issue in that they reveal all the missing links on a site (although some don't actually tell you the page they are on), but you still have to sort them to see if the links/ resource is related to your theme. When you're on a niche site, this obviously isn't an issue, but on a site like Mashable (to use the example given in a recent SEOmoz blog) it could result in wading through hundreds of links to find one relevant one right at the end. Is there a tool that allows you to specify what theme links you are looking for from a site, or better yet one that allows you to check multiple sites for multiple missing themed links in one go? Or is the best way to export the list and just search the document for certain keywords?
