Thinking about not indexing PDFs on a product page
-
Our product pages generate a PDF version of the page in a different layout. This is done for 2 reasons, it's been the standard across similar industries and to help customers print them when working with the product.
So there is a use when it comes to the customer but search? I've thought about this a lot and my thinking is why index the PDF at all? Only allow the HTML page to be indexed. The PDF files are in a subdomain, so I can easily no index them. The way I see it, I'm reducing duplicate content
On the flip side, it is hosted in a subdomain, so the PDF appearing when a HTML page doesn't, is another way of gaining real estate. If it appears with the HTML page, more estate coverage.
Anyone else done this? My knowledge tells me this could be a good thing, might even iron out any backlinks from being generated to the PDF and lead to more HTML backlinks
Can PDFs solely exist as a form of data accessible once on the page and not relevant to search engines. I find them a bane when they are on a subdomain.

Thanks EGOL, I didn't think about using rel=canonical on htaccess. Great idea
-
If you link to a pdf, some of your power flows into it. If someone else links to a pdf, some of his power flows into it.
PDFs accumulate backlinks, accumulate pagerank. You should assign these valuable assets to real pages.
So, if you have pdfs that are duplicates of webpages then you should use rel=canonical using htaccess to attribute them to their matched webpage. If you don't do that then you assets are being squandered.

I don't think see my PDFs show up for a search term when my HTML pages are being displayed.
However, there was a situation when a PDF was displayed and I created a HTML page of it and set up redirects from the PDF to the HTML page. I followed that up by reuploading the PDF as a new URL and offering to download. That way I transfered the rank juice to the HTML page.
In a nutshell, no I don't see my PDFs outranking my HTML pages, but I do know my PDFs are indexed and I don't know if they show up for a different search term.
I guess my main question is, would not indexing them open up the chance for more backlinks to your HTML page and not the PDF? And in Google's eyes, it won't debate over which to display, the HTML page or PDF as both have the same content.
Maybe I'm over thinking and the straight answer is, if a HTML page exists, Google won't give preference to the PDF but in the event there is no HTML, the PDF is shown
-
Yeah, we offer the same. The user is able to download the PDF or have it open in a new window. I haven't seen Google automatically present my PDF and so far my searches have shown my HTML page, but my question to Cole remains, could Google be comparing the PDF and HTML page with each other? What if in a search situation it would prefer showing the PDF higher than the HTML page?
On your next question, I don't get duplicate warning for PDF. I believe the PDFs are indeed being indexed as the text is readable. How well are they being indexed? I've got close to 22,000 search results for my subdomain so yeah, they are indexed.
I do have rel-canonical tags on the HTML page, but can't appear it on the PDF as it's a file and not a page.

Thanks for the replies
Cole - Google indexed our PDFs though. I tested this by doing a site:domain.com search term, and then a site:static.domain.com search term search.
Result:
site:static.domain.com search term
Google showed me the PDF document that is available for download from the HTML page that ranks high for that search term search.
So Google is indexing both the PDF and HTML. To answer your question as to why I don't want them indexed.. Well, my thinking was. If the PDF appears and if someone backlinks to it, I rather get that backlink to the HTML page. PDFs are hosted on my subdomain and I don't want the subdomain to get the rank. Back of my head, I'm also debating, whether my PDF and HTML are competing with each other?

The way I see it, I'm reducing duplicate content.
Anything you can do that helps with this, is a good move - nothing wrong with a little tidying up.
the PDF appearing when a HTML page doesn't, is another way of gaining real estate
Do you currently have this happen? PDF's can actually out-rank HTM pages on occasion - they aren't the preferred media type of Google, but like any page, it's all about the content.

Morning,
To my knowledge Google isn't able to open a PDF. You could always present the users with the option of downloading a PDF. Any tech website I have been to generally offers it in a download, or opens it in another window.
I don't know why it would automatically present a PDF, although, I probably don't work in the same industry! Ha!
The other question I have is, are you getting Duplicate content warnings? Are the PDF's currently being indexed? If so, how well are they being Indexed? Google can read an open PDF, or a PDF that automatically displays, but some are easier to read that others depending on the settings of the PDF.

Another option is the rel canonical tags?
Hope this helps!

"I'm reducing duplicate content " - Google cannot crawl PDFs, but they do index them and show them in search results.
So let me ask you - why do you not want them indexed?
I say let them be indexed.

When serving a 410 for page gone, should I serve an error page?
I'm removing a bunch of old & rubbish pages and was going to serve 410 to tell google they're gone (my understanding is it'll get them out of the index a bit quicker than a 404). I should still serve an error page though, right? Similar to a 404. That doesn't muddy the "gone" message that I'm giving Google? There's no need to 410 and die?

Why does Google rank a product page rather than a category page?
Hi, everybody In the Moz ranking tool for one of our client's (the client sells sport equipment) account, there is a trend where more and more of their landing pages are product pages instead of category pages. The optimal landing page for the term "sleeping bag" is of course the sleeping bag category page, but Google is sending them to a product page for a specific sleeping bag.. What could be the critical factors that makes the product page more relevant than the category page as the landing page?

Interlinking from unique content page to limited content page
I have a page (page 1) with a lot of unique content which may rank for "Example for sale". On this page I Interlink to a page (page 2) with very limited unique content, but a page I believe is better for the user with anchor "See all Example for sale". In other words, the 1st page is more like a guide with items for sale mixed, whereas the 2nd page is purely a "for sale" page with almost no unique content, but very engaging for users. Questions: Is it risky that I interlink with "Example for sale" to a page with limited unique content, as I risk not being able to rank for either of these 2 pages Would it make sense to "no index, follow" page 2 as there is limited unique content, and is actually a page that exist across the web on other websites in different formats (it is real estate MLS listings), but I can still keep the "Example for sale" link leading to page 2 without risking losing ranking of page 1 for "Example for sale"keyword phrase I am basically trying to work out best solution to rank for "Keyword for sale" and dilemma is page 2 is best for users, but is not a very unique page and page 2 is very unique and OK for users but mixed up writing, pictures and more with properties for sale.

Shopify Product Variants vs Separate Product Pages
Let's say I have 10 different models of hats, and each hat has 5 colors. I have two routes I could take: a) Make 50 separate product pages Pros: -Better usability for customer because they can shop for just masks of a specific color. We can sort our collections to only show our red hats. -Help SEO with specific kw title pages (red boston bruins hat vs boston bruins hat). Cons: -Duplicate Content: Hat model in one color will have almost identical description as the same hat in a different color (from a usability and consistency standpoint, we'd want to leave descriptions the same for identical products, switching out only the color) b) Have 10 products listed, each with 5 color variants Pros: -More elegant and organized -NO duplicate Content Cons: -Losing out on color specific search terms -Customer might look at our 'red hats' collection, but shopify will only show the 'default' image of the hat, which could be another color. That's not ideal for usability/conversions. Not sure which route to take. I'm sure other vendors must have faced this issue before. What are your thoughts?

I have been optimizing this page for a few weeks now and and have seen our page for up from 23rd to 11th on the serp's.

I am not sure what happened here but any advice on how I could fix this would be great. My site is www.mynaturalmarket.com and the keyword I'm working on is Zyflamend.

How to avoid content canibalizm? How do I control which page is the landing page?
Hi All, To clarify my question I will give an example. Let's assume that I have a laptop e-commerce site and that one of my main categories is Samsung Laptops. The category page shows lots of laptops and a small section of text. On the other hand, in my article section I have a HUGE article about Samsung Laptops. If we consider the two word phrases each page is targeting then the answer is the same - Samsung Laptops. On the article i point to the category page using anchor such as "buy samsung laptops" or "samsung laptops" and on the category page (my wishful landing page) I point to the article with "learn about samsung laptops" or "samsung laptops pros and cons". Thanks

Pricing Page vs. No Pricing Page
There are many SEO sites out there that have an SEO Pricing page, IMO this is BS. A SEO company cannot give every person the same quote for diffirent keywords. However, this is something we are currently debating. I don't want a pricing page, because it's a page full of lies. My coworker thinks it is a good idea, and that users look for a pricing page. Suggestions? If I had to build one (which I am debating against) is it better to just explain why pricing can be tricky? or to BS them like most sites do?
