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.

I've been asked to look at a site that has lost 70/80% if their search traffic. This happened suddenly around the 17th April. Traffic dropped off over a couple of days and then flat-lined over the next couple of weeks. The screenshot attached, shows the impressions/clicks reported in GWT. When I investigated I found: There had been no changes/updates to the site in question There were no messages in GWT indicating a manual penalty The number of pages indexed shows no significant change There are no particular trends in keywords/queries affected (they all were.) I did discover that ahrefs.com showed that a large number of links were reported lost on the 17th April. (17k links from 1 domain). These links reappeared around the 26th/27th April. But traffic shows no sign of any recovery. The links in question were from a single development server (that shouldn't have been indexed in the first place, but that's another matter.) Is it possible that these links were, maybe artificially, boosting the authority of the affected site? Has the sudden fluctuation in such a large number of links caused the site to trip an algorithmic penalty (penguin?) Without going into too much detail as I'm bound by client confidentiality - The affected site is really a large database and the links pointing to it are generated by a half dozen or so article based sister sites based on how the articles are tagged. The links point to dynamically generated content based on the url. The site does provide a useful/valuable service/purpose - it's not trying to "game the system" in order to rank. That doesn't mean to say that it hasn't been performing better in search than it should have been. This means that the affected site has ~900,000 links pointing to is that are the names of different "entities". Any thoughts/insights would be appreciated. I've expresses a pessimistic outlook to the client, but as you can imaging they are confused and concerned. LVSceCN.png

Maybe I've been living under a rock, but I was surprised to see that Google had algorithmically modified my page titles in the search results by adding the company name to the end of the (short) title. <title>About Us</title> became  About Us - Company Name Interestingly, this wasn't consistent - sometimes it was "company name Limited" and sometimes just "company name. Anyone else notice this or is this a recent change?
