      Hi guys,

      Does anyone know why a site can contain duplicate URLs ending with hastag & exclamation mark e.g.

      https://site.com.au/#!

      We are finding a lot of these URLs (as duplicates) and i was wondering what they are from developer standpoint?

      And do you think it's worth the time and effort adding a rel canonical tag or 301 to these URLs eventhough they're not getting indexed by Google?

      Cheers,

      Chris

          The URL you displayed as an example looks like in-page bookmarking and as far as my knowledge goes this does not make the content duplicated.

          But as far as the canonicals are concern, adding a canonical URL on the website is better as it can save you from any unforeseen problems but as far as the problem you are mentioning is concern, I don’t think this will create a duplicate content within your website.

          Hope this helps!

            Duplicate content on recruitment website

            Hi everyone, It seems that Panda 4.2 has hit some industries more than others. I just started working on a website, that has no manual action, but the organic traffic has dropped massively in the last few months. Their external linking profile seems to be fine, but I suspect usability issues, especially the duplication may be the reason. The website is a recruitment website in a specific industry only. However, they posts jobs for their clients, that can be very similar, and in the same time they can have 20 jobs with the same title and very similar job descriptions. The website currently have over 200 pages with potential duplicate content. Additionally, these jobs get posted on job portals, with the same content (Happens automatically through a feed). The questions here are: How bad would this be for the website usability, and would it be the reason the traffic went down? Is this the affect of Panda 4.2 that is still rolling What can be done to resolve these issues? Thank you in advance.

            Does Google Read URL's if they include a # tag? Re: SEO Value of Clean Url's

            An ECWID rep stated in regards to an inquiry about how the ECWID url's are not customizable, that "an important thing is that it doesn't matter what these URLs look like, because search engines don't read anything after that # in URLs. " Example http://www.runningboards4less.com/general-motors#!/Classic-Pro-Series-Extruded-2/p/28043025/category=6593891 Basically all of this: #!/Classic-Pro-Series-Extruded-2/p/28043025/category=6593891 That is a snippet out of a conversation where ECWID said that dirty urls don't matter beyond a hashtag... Is that true? I haven't found any rule that Google or other search engines (Google is really the most important) don't index, read, or place value on the part of the url after a # tag.

            How to deal with URLs and tabbed content

            Hi All, We're currently redesigning a website for a new home developer and we're trying to figure out the best way to deal with tabbed content in the URL structure. The design of the site at the moment will have a page for a development and within that you can select your house type, then when on the house type page there will be tabs displayed for the user to see things like the plot map, availability and pricing, specifications, etc. The way our development team are looking at handling this is for the URL to use a hashtag or a query string at the end of it so we can still land users on these specific tabs for PPC for example. My question is really, has anyone had any experience with this? Any recommendations on how to best display the urls for SEO? Thanks

            No-index pages with duplicate content?

            Hello, I have an e-commerce website selling about 20 000 different products. For the most used of those products, I created unique high quality content. The content has been written by a professional player that describes how and why those are useful which is of huge interest to buyers. It would cost too much to write that high quality content for 20 000 different products, but we still have to sell them. Therefore, our idea was to no-index the products that only have the same copy-paste descriptions all other websites have. Do you think it's better to do that or to just let everything indexed normally since we might get search traffic from those pages? Thanks a lot for your help!

            Avoiding Duplicate Content with Used Car Listings Database: Robots.txt vs Noindex vs Hash URLs (Help!)

            Hi Guys, We have developed a plugin that allows us to display used vehicle listings from a centralized, third-party database. The functionality works similar to autotrader.com or cargurus.com, and there are two primary components: 1. Vehicle Listings Pages: this is the page where the user can use various filters to narrow the vehicle listings to find the vehicle they want.
            2. Vehicle Details Pages: this is the page where the user actually views the details about said vehicle. It is served up via Ajax, in a dialog box on the Vehicle Listings Pages. Example functionality:  http://screencast.com/t/kArKm4tBo The Vehicle Listings pages (#1), we do want indexed and to rank. These pages have additional content besides the vehicle listings themselves, and those results are randomized or sliced/diced in different and unique ways. They're also updated twice per day. We do not want to index #2, the Vehicle Details pages, as these pages appear and disappear all of the time, based on dealer inventory, and don't have much value in the SERPs. Additionally, other sites such as autotrader.com, Yahoo Autos, and others draw from this same database, so we're worried about duplicate content. For instance, entering a snippet of dealer-provided content for one specific listing that Google indexed yielded 8,200+ results:  Example Google query. We did not originally think that Google would even be able to index these pages, as they are served up via Ajax. However, it seems we were wrong, as Google has already begun indexing them. Not only is duplicate content an issue, but these pages are not meant for visitors to navigate to directly! If a user were to navigate to the url directly, from the SERPs, they would see a page that isn't styled right. Now we have to determine the right solution to keep these pages out of the index:  robots.txt, noindex meta tags, or hash (#) internal links. Robots.txt Advantages: Super easy to implement Conserves crawl budget for large sites Ensures crawler doesn't get stuck. After all, if our website only has 500 pages that we really want indexed and ranked, and vehicle details pages constitute another 1,000,000,000 pages, it doesn't seem to make sense to make Googlebot crawl all of those pages. Robots.txt Disadvantages: Doesn't prevent pages from being indexed, as we've seen, probably because there are internal links to these pages. We could nofollow these internal links, thereby minimizing indexation, but this would lead to each 10-25 noindex internal links on each Vehicle Listings page (will Google think we're pagerank sculpting?) Noindex Advantages: Does prevent vehicle details pages from being indexed Allows ALL pages to be crawled (advantage?) Noindex Disadvantages: Difficult to implement (vehicle details pages are served using ajax, so they have no tag. Solution would have to involve X-Robots-Tag HTTP header and Apache, sending a noindex tag based on querystring variables, similar to this stackoverflow solution. This means the plugin functionality is no longer self-contained, and some hosts may not allow these types of Apache rewrites (as I understand it) Forces (or rather allows) Googlebot to crawl hundreds of thousands of noindex pages.  I say "force" because of the crawl budget required.  Crawler could get stuck/lost in so many pages, and my not like crawling a site with 1,000,000,000 pages, 99.9% of which are noindexed. Cannot be used in conjunction with robots.txt. After all, crawler never reads noindex meta tag if blocked by robots.txt Hash (#) URL Advantages: By using for links on Vehicle Listing pages to Vehicle Details pages (such as "Contact Seller" buttons), coupled with Javascript, crawler won't be able to follow/crawl these links.  Best of both worlds:  crawl budget isn't overtaxed by thousands of noindex pages, and internal links used to index robots.txt-disallowed pages are gone. Accomplishes same thing as "nofollowing" these links, but without looking like pagerank sculpting (?) Does not require complex Apache stuff Hash (#) URL Disdvantages: Is Google suspicious of sites with (some) internal links structured like this, since they can't crawl/follow them? Initially, we implemented robots.txt--the "sledgehammer solution." We figured that we'd have a happier crawler this way, as it wouldn't have to crawl zillions of partially duplicate vehicle details pages, and we wanted it to be like these pages didn't even exist. However, Google seems to be indexing many of these pages anyway, probably based on internal links pointing to them. We could nofollow the links pointing to these pages, but we don't want it to look like we're pagerank sculpting or something like that. If we implement noindex on these pages (and doing so is a difficult task itself), then we will be certain these pages aren't indexed. However, to do so we will have to remove the robots.txt disallowal, in order to let the crawler read the noindex tag on these pages. Intuitively, it doesn't make sense to me to make googlebot crawl zillions of vehicle details pages, all of which are noindexed, and it could easily get stuck/lost/etc. It seems like a waste of resources, and in some shadowy way bad for SEO. My developers are pushing for the third solution:  using the hash URLs. This works on all hosts and keeps all functionality in the plugin self-contained (unlike noindex), and conserves crawl budget while keeping vehicle details page out of the index (unlike robots.txt). But I don't want Google to slap us 6-12 months from now because it doesn't like links like these (). Any thoughts or advice you guys have would be hugely appreciated, as I've been going in circles, circles, circles on this for a couple of days now. Also, I can provide a test site URL if you'd like to see the functionality in action.

            Does having a ? on the end of your URL affect your SEO?

            I have some redirects that were done with at "?" at the end of the URL to include google coding (i.e. you click on an adwords link and the google coding follows the redirected link). When there is not coding to follow the link just appears as "filename.html?". Will that affect us negatively SEO-wise? Thank you.

            Overly-Dynamic URL

            Hi, We have over 5000 pages showing under Overly-Dynamic URL error Our ecommerce site uses Ajax and we have several different filters like, Size, Color, Brand and we therefor have many different urls like, http://www.dellamoda.com/Designer-Pumps.html?sort=price&sort_direction=1&use_selected_filter=Y http://www.dellamoda.com/Designer-Accessories.html?sort=title&use_selected_filter=Y&view=all http://www.dellamoda.com/designer-handbags.html?use_selected_filter=Y&option=manufacturer%3A&page3 Could we use the robots.txt file to disallow these from showing as duplicate content? and do we need to put the whole url in there? like: Disallow: /*?sort=price&sort_direction=1&use_selected_filter=Y if not how far into the url should be disallowed? So far we have added the following to our robots,txt Disallow: /?sort=title Disallow: /?use_selected_filter=Y Disallow: /?sort=price Disallow: /?clearall=Y Just not sure if they are correct. Any help would be greatly appreciated. Thank you,Kami

            URL Structure for Directory Site

            We have a directory that we're building and we're not sure if we should try to make each page an extension of the root domain or utilize sub-directories as users narrow down their selection. What is the best practice here for maximizing your SERP authority? Choice #1 - Hyphenated Architecture (no sub-folders): State Page /state/ City Page /city-state/ Business Page /business-city-state/
            4) Location Page  /locationname-city-state/ or.... Choice #2 - Using sub-folders on drill down: State Page /state/ City Page /state/city Business Page /state/city/business/
            4) Location Page  /locationname-city-state/ Again, just to clarify, I need help in determining what the best methodology is for achieving the greatest SEO benefits. Just by looking it would seem that choice #1 would work better because the URL's are very clear and SEF. But, at the same time it may be less intuitive for search. I'm not sure. What do you think?
