Would a free PDF download diminish SEO benefits of HTML content?
-
Hello,
I am doing SEO for a company that, as a sideline business, sells four books written by the principals; the content is directly relevant to the company's primary business focus. Book sales are a tiny fraction of our overall revenue, and we don't expect that to change, although we will continue to sell the books.
In addition to selling them, we have decided to convert the books to HTML and post them for free on our website (laid out by chapter and section). The hope is that this will result in goodwill, links, traffic, and ultimately improved search rankings.
My question: Would offering free PDF downloads of the books (in addition to posting the HTML content) diminish the SEO benefits of the HTML content?
- If we don't offer the PDF option, people would have to visit our site to read the content (unless they bought a hard copy).
- If visitors were able to download a free PDF, they wouldn't need to return to our site to read it.
- If our corporate clients (nearly all of our clients are corporations) could download a PDF, they could then post it on an intranet instead of posting a link to our site.
- In general, do you think a visitor would be less likely to link to our site if he or she were able to download the PDF? Or would the appeal of the PDF option make it more likely that people would visit and link to the site?
- Also, if we offer the PDF option, are there any SEO issues related to duplicate content?
- Finally, if we did offer the free PDF download, would you recommend that we ask for an email address before giving the PDF?
Thank you very much!

Okay, thanks.

I make nice money from ads on html pages. And, if you have ten chapters that each focus on a different keyword, then you have ten html pages in the SERPs with great optimization instead of one PDF with generalized optimization. And when people land they look at many pages, often all ten. Each of these earns ad impressions. I am publishing for ad revenue.

Thank you, Alex!

Thank you, EGOL!
Do you think there is any reason to consider offering PDFs and not posting the HTML versions? Or do you prefer the approach of having the HTML and also offering PDFs?

You can add canonical HTTP headers to the PDFs to avoid any duplicate content problems: http://moz.com/blog/how-to-advanced-relcanonical-http-headers
If you think these PDFs are really valuable, and e-mail addresses will be useful to you, then yes - you should ask for an e-mail address to download them. If you don't take that route and they're indexed as part of your website, make sure you have a few links to your websites within the PDFs so you get some value if people rehost them.
Make sure your branding and website is obvious on the PDFs whatever you do.

There are many ways to handle this.
I have sites with lots of free pdf documents. Each of those documents contains content that is not on the website. Lots of people visit and print them. Lots of people link to them. When they are printed our branding is prominently displayed so that people can return for our site to get other similar documents. We also have one or more links in those pdf documents so any links into them pass value into our website. If someone else posts them on their domain the links again point to our website. In addition, the properties of the pdf documents are edited to give them a title tag that will be visible in the SERPs and help them rank better.
It is possible to monetize pdf documents. You can rent/sell adspace within them that can be linked or not be linked. Many shopping carts allow you to produce "add to cart" buttons. These can be configured to work within pdf documents.
A friend of mine has a situation like yours. He has a collection of webpages that are each chapters of a single topic document that he also has in a pdf document with many pages. People can view the html pages on his site for free (they are monetized by ads). Or, they can purchase the pdf. The pdf allows them to print the document, search the entire document, view it offline or conveniently page through it linearly. He has many of these pdf documents and even though people can view the same content free on his website many of them purchase these pdfs for the print/search/scroll/use-offline abilities. He makes nice money from selling these pdf documents.

MAKE 'EM PAY FOR THE PDF -
if visitors were able to download a free PDF, they wouldn't need to return to our site to read it.

MAKE 'EM PAY FOR THE PDF
- In general, do you think a visitor would be less likely to link to our site if he or she were able to download the PDF? Or would the appeal of the PDF option make it more likely that people would visit and link to the site?
MOST PEOPLE WILL NOT LINK. ONLY PEOPLE WHO WANT TO SAY... "GET SOMETHING AWESOME HERE". THE PROBLEM IS THAT THEY WILL LINK TO THE PDF BUT IF YOU HAVE LINKS IN THE PDF THEN YOUR WEBSITE WILL GET SOME BENEFIT. BUT I WOULD BE SELLING THIS PDF.
- Also, if we offer the PDF option, are there any SEO issues related to duplicate content?
IF YOU HAVE 500 WORDS ON AN HTML PAGE AND THE SAME 500 WORDS IN A PDF THEN YOU MIGHT HAVE A PROBLEM. BUT IF YOU HAVE 50 PAGES EACH OF 500 WORDS ON THE WEBSITE AND 25000 WORDS IN ONE PDF DOCUMENT THEN THERE SHOULD BE NO PROBLEM. BUT IF YOU SELL THE PDF THAT CONCERN IS ELIMINATED.
- Finally, if we did offer the free PDF download, would you recommend that we ask for an email address before giving the PDF?
IS GETTING THE EMAIL ADDRESSES A GOAL? IF THAT IS WHY YOU ARE DOING THIS THEN, YES, ASK FOR IT, AND REQUIRING THE EMAIL IN ADVANCE SUGGESTS THAT THE PDF WILL NOT BE INDEXED WHERE IT CAN BE LINKED TO OR HAVE ANY CHANCE OF BEING A DUPE CONTENT PROBLEM. I WOULD BE SELLING THE PDF.

Delete or not delete outdated content
Hi there!
On-Page Optimization | | Enrico_Cassinelli
We run a website about a region in Italy, the Langhe area, where we write about wine and food, local culture, and we give touristic informations. The website also sports a nice events calendar: in 4 years we (and our users) loaded more than 5700 events. Now, we're starting to have some troubles managing this database. The database related to events is huge both in file size and number of rows. There are a lot of images that eat up disk space, and also it's becoming difficult to manage all the data in our backend. Also, a lot of users are entering the website by landing on outdated events. I was wondering if it could be a good idea to delete events older than 6 months: the idea was to keep only the most important and yearly recurring events (which we can update each year with fresh information), and trash everything else. This of course means that 404 errors will increase, and also that our content will gettin thinner, but at the same time we'll have a more manageable database, and the content will be more relevant and "clean". What do you think? thank you 🙂 Best0 -

Any practical tips how to optimize such sites especially when there is not much content. Best

Duplicate Content
I'm currently working on a site that sells appliances. Currently, there are thousands of "issues" with this site, many of them dealing with duplicate content. Now, the product pages can be viewed in "List" or "Grid" format. As Lists, they have very little in the way of content. My understanding is that the duplicate content arises from different URLs going to the same site. For instance, the site might have a different URL when told to display 9 items than when told to display 15. This could then be solved by inserting rel = canonical. Is there a way to take a site and get a list of all possible duplicates? This would be much easier than slogging through every iteration of the options and copying down the URLs. Also, is there anything I might be missing in terms of why there is duplicate content? Thank you.

Duplicate content issues?
Our company consists of several smaller companies, some of whom deal with very similar things. For instance, two of our companies resell accounts software, but only one provides after-sales support. Because of the number of different companies and websites we have, sometimes it would be easier to simply copy content from one site to the other, optimised in the same manner as, in some instances, we would want different websites to rank for the same keywords. I have been asked my opinion on the potential impact of this practice and my initial response was that we should avoid this due to potential penalties. However, I thought I'd garner opinion from a wider audience before making any recommendations either way. What do people think? Thanks.

The problme mainly coming in photo gallery posts. for example: this is the main url of a post. apgossips.com/2012/12/18/telugu-actress-poonam-kaur-photos . But in this post, each image is a link to its enlarged images (default wordpress). The problem is coming with each individual image with in this post. examples of SEOMOZ report 3 individual urls as duplicate content...from the same above post.: http://apgossips.com/2012/12/18/telugu-actress-poonam-kaur-photos/poonam-kaur-hot-photo-shoot-stills-4 http://apgossips.com/2012/12/18/telugu-actress-poonam-kaur-photos/poonam-kaur-hot-photo-shoot-stills-3 http://apgossips.com/2012/12/18/telugu-actress-poonam-kaur-photos/poonam-kaur-hot-photo-shoot-stills-2 Some body please advise me.. Appreciate your help.

Duplicate Content Issues with Forum
Hi Everyone, I just signed up last night and received the crawl stats for my site (ShapeFit.com). Since April of 2011, my site has been severely impacted by Google's Panda and Penguin algorithm updates and we have lost about 80% of our traffic during that time. I have been trying to follow the guidelines provided by Google to fix the issues and help recover but nothing seems to be working. The majority of my time has been invested in trying to add content to "thin" pages on the site and filing DMCA notices for copyright infringement issues. Since this work has not produced any noticeable recovery, I decided to focus my attention on removing bad backlinks and this is how I found SEOmoz. My question is about duplicate content. The crawl diagnostics showed 6,000 errors for duplicate page content and the same for duplicate page title. After reviewing the details, it looks like almost every page is from the forum (shapefit.com/forum). What's the best way to resolve these issues? Should I completely block the "forum" folder from being indexed by Google or is there something I can do within the forum software to fix this (I use phpBB)? I really appreciate any feedback that would help fix these issues so the site can hopefully start recovering from Panda/Penguin. Thank you, Kris

What is the most SEO friendly Shopping Cart?
What is the most SEO friendly shopping cart? I have been using zen-cart for 6 years. Seems Google doesn't like it as much as other carts. I started a new site about 6 months ago using Magento. When I build links to this site the terms move. The terms are very similar. So I would imagine the competition is the same. I am curious if anybody has tried with different carts and found anyone to be better than the others. Also the new site has about one tenth the amount of products but has a lot more pages indexed.
