Multiple URLs for the same page
-
I am working with a client and recently discovered that they have several URLs that go to the same page.

http://www.maps.com/FunFacts
http://www.maps.com/funfacts.aspx?.nav=FFI am afraid this is happening all over the site. So, my question is:
Is this hurting the SEO and how?
If so what is the best way to go about fixing this problem?
Thanks for your help!

Prob not a good idea to post client URLs.

Hey, thanks guys for the great feedback!

Yes, it is hurting the SEO. For more information than you might ever wanted to know about this, see the comprehensive blog post that Dr. Pete (an SEOmoz associate) posted last night at http://www.seomoz.org/blog/duplicate-content-in-a-post-panda-world. That should be a good starting point to understand why you don't want this happening, and how to start to fix it. The comments touch on case sensitivity as well, even though he didn't include that in the post itself.

Hello,
This is seriously hurting your seo. The best way to get it over to implement canonical links in the head section of each page, so that it will tell google which page to display in the serps. You should choose the all lovercase letter one with no .aspx ending.

Yes this hurts SEO. Mostly in that search engines rank pages based on the URL as a the URL is the only unique identifier they have for a given page.
This means link popularity is split amongst the URLs and the same page is competing with its self to rank so Google usually picks one and ignores the others, and then you lose all of the link juice for links to the others.
So with that said there are multiple ways to fix this. The most useful one is to setup 301 redirects for every option and redirect the user to the one you want to use. This way even if an outside source links to one of the variations google will go through that link, hit the redirect, and see the final URL and use that for ranking. Going the 301 route also keeps your stats programs much cleaner as you won't see stats for various versions of the pages.
The hard part with 301s is catching all variations of a URL.
With that said you might have a 301 in place, but then have parameters passed to the URL often. This is where the rel=canonical tag comes in handy.
rel=canonical is a tag you can place in a page that tells anyone who cares (search bots mostly) that if you see this page at a URL other than the canonical URL you need to treat it as the same page as the canonical URL (that is a simplification, but works for the most part).
So, get 301's in place, and then in your template for each page get a rel=canonical tag setup with the base URL so you are taken care of on both fronts...
This can be rough on huge sites, but there is usually a programmatic way to do this to catch a good portion of your pages.

Page rank and menus
Hi, My client has a large website and has a navigation with main categories. However, they also have a hamburger type navigation in the top right. If you click it it opens to a massive menu with every category and page visible. Do you know if having a navigation like this bleeds page rank? So if all deep pages are visible from the hamburger navigation this means that page rank is not being conserved to the main categories. If you click a main category in the main navigation (not the hamburger) you can see the sub pages. I think this is the right structure but the client has installed this huge menu to make it easier for people to see what there is. From a technical SEO is this not bad?

URL structure - Page Path vs No Page Path
We are currently re building our URL structure for eccomerce websites. We have seen a lot of site removing the page path on product pages e.g. https://www.theiconic.co.nz/liberty-beach-blossom-shirt-680193.html versus what would normally be https://www.theiconic.co.nz/womens-clothing-tops/liberty-beach-blossom-shirt-680193.html Should we be removing the site page path for a product page to keep the url shorter or should we keep it? I can see that we would loose the hierarchy juice to a product page but not sure what is the right thing to do.

Best-practice URL structures with multiple filter combinations
Hello, We're putting together a large piece of content that will have some interactive filtering elements. There are two types of filters, topics and object types. The architecture under the hood constrains us so that everything needs to be in URL parameters. If someone selects a single filter, this can look pretty clean: www.domain.com/project?topic=firstTopic
Intermediate & Advanced SEO | | digitalcrc
or
www.domain.com/project?object=typeOne The problems arise when people select multiple topics, potentially across two different filter types: www.domain.com/project?topic=firstTopic-secondTopic-thirdTopic&object=typeOne-typeTwo I've raised concerns around the structure in general, but it seems to be too late at this point so now I'm scratching my head thinking of how best to get these indexed. I have two main concerns: A ton of near-duplicate content and hundreds of URLs being created and indexed with various filter combinations added Over-reacting to the first point above and over-canonicalizing/no-indexing combination pages to the detriment of the content as a whole Would the best approach be to index each single topic filter individually, and canonicalize any combinations to the 'view all' page? I don't have much experience with e-commerce SEO (which this problem seems to have the most in common with) so any advice is greatly appreciated. Thanks!0 -
Location Pages On Website vs Landing pages
We have been having a terrible time in the local search results for 20 + locations. I have Places set up and all, but we decided to create location pages on our sites for each location - brief description and content optimized for our main service. The path would be something like .com/location/example. One option that has came up in question is to create landing pages / "mini websites" that would probably be location-example.url.com. I believe that the latter option, mini sites for each location, would be a bad idea as those kinds of tactics were once spammy in the past. What are are your thoughts and and resources so I can convince my team on the best practice.

Date of page first indexed or age of a page?
Hi does anyone know any ways, tools to find when a page was first indexed/cached by Google? I remember a while back, around 2009 i had a firefox plugin which could check this, and gave you a exact date. Maybe this has changed since. I don't remember the plugin. Or any recommendations on finding the age of a page (not domain) for a website? This is for competitor research not my own website. Cheers, Paul

Where to put a page ID in a URL?
Hello, My company is going to change URLs to example.com/category or example.com/product. When we will change the URLs to product or category pages somehow we have to check whether the requested page is from category table in DB or from products table (this gives much speed to page load time). So we have to choose how to make the different product and category pages.
Intermediate & Advanced SEO | | komeksimas
Programmers said that we need to insert id to URL. So the question is: Which is the better way to place an id to an URL? example.com/product-name?id=111 example.com/product-name/111 example.com/product_name-111 Or maybe we should use some other punctuation mark to separate id from product name? p.s. I have read Dynamic URLs vs. static URLs by Google and it still didn't answered which is the best for all of the pages. Somehow others solve this problem by typing only the names to the URL, but could anyone tell what that technology should be?0 -
Dynamic pages - ecommerce product pages
Hi guys, Before I dive into my question, let me give you some background.. I manage an ecommerce site and we're got thousands of product pages. The pages contain dynamic blocks and information in these blocks are fed by another system. So in a nutshell, our product team enters the data in a software and boom, the information is generated in these page blocks. But that's not all, these pages then redirect to a duplicate version with a custom URL. This is cached and this is what the end user sees. This was done to speed up load, rather than the system generate a dynamic page on the fly, the cache page is loaded and the user sees it super fast. Another benefit happened as well, after going live with the cached pages, they started getting indexed and ranking in Google. The problem is that, the redirect to the duplicate cached page isn't a permanent one, it's a meta refresh, a 302 that happens in a second. So yeah, I've got 302s kicking about. The development team can set up 301 but then there won't be any caching, pages will just load dynamically. Google records pages that are cached but does it cache a dynamic page though? Without a cached page, I'm wondering if I would drop in traffic. The view source might just show a list of dynamic blocks, no content! How would you tackle this? I've already setup canonical tags on the cached pages but removing cache.. Thanks
