      Will registered trademark symbol within a URL be bad? I know some special characters are unsafe (#, >, etc.) but can not find anything that mentions registered trademark.

      Thanks!

        Jen - I agree with Eli.  It's best not to use the TM symbol in a URL string  - it will confuse the end user when it's URL encoded and scrambled.  Rather, put the mark on your pages and in images.

        If you have gone through the registration process with the USPTO (United States Patent and Trademark Office), you should be using the ® symbol next to your mark, and not the TM symbol.

        According to the Trademark FAQs on the USPTO site: http://www.uspto.gov/faq/trademarks.jsp#_Toc275426682

        Do federal regulations govern the use of the designations "TM" or "SM" or the ® symbol?

        If you claim rights to use a mark, you may use the "TM" (trademark) or "SM" (service mark) designation to alert the public to your claim of a “common-law” mark.  No registration is necessary to use a "TM" or "SM" symbol and you may continue to use these symbols even if the USPTO refuses to register your mark.  Those symbols put people on notice that you claim rights in the mark, although common law doesn't give you all the rights and benefits of federal registration.

        You may only use the federal registration symbol "®" after the USPTO actually registers a mark, not while an application is pending.  And it may only be used on or in connection with the goods/services listed in the federal trademark registration and while the registration is still alive (you may not continue to use it if you don’t maintain the registration or it expires).  Although there are no specific requirements on where the symbol should be placed relative to the mark, most businesses use the symbol in the upper right corner of the mark.  Note: Because several foreign countries use “®” to indicate that a mark is registered in that country, use of the symbol by the holder of a foreign registration may be proper.

        From another section_:  There are no specific requirements on where the “®” symbol should be placed relative to the mark, but most businesses use the symbol in the upper right corner of the mark._

        Hope this helps!

          Jen,

          I'm not sure if it will be bad based on research, but based on what you aim for in a URL (clarity, what the article is about, user experience, descriptive keywords, etc...) the TM Registered may not fit well.

          Plus, be careful, your TM (if using symbols) will get changed to ® (®) or ™ (™) in the URL - making it less user friendly to type in (let alone look at)..

          Hope this Helps!

            Trailing slash URLs and canonical links

            Hi, I've seen a fair amount of topics speaking about the difference between domain names ending with or without trailing slashes, the impact on crawlers and how it behaves with canonical links.
            However, it sticks to domain names only.
            What about subfolders and pages then? How does it behaves with those? Say I've a site structured like this:
            https://www.domain.com
            https://www.domain.com/page1 And for each of my pages, I've an automatic canonical link ending with a slash.
            Eg. rel="canonical" href="https://www.domain.com/page1/" /> for the above page. SEM Rush flags this as a canonical error. But is it exactly?
            Are all my canonical links wrong because of that slash? And as subsidiary question, both domain.com/page1 and domain.com/page1/ are accessible. Is it this a mistake or it doesn't make any difference (I've read that those are considered different pages)? Thanks!
            G

            URL - Well Formed or Malformed

            Hi Mozzers, I've been mulling over whether my URLs could benefit a little SEO tweaking. I'd be grateful for your opinion. For instance, we've a product, a vintage (second hand), red Chanel bag. At the moment the URL is: www.vintageheirloom.com/vintage-chanel-bags/2.55-bags/red-2.55-classic-double-flap-bag-1362483150 Broken down... vintage-chanel-bags = this is the main product category, i.e. vintage chanel bags 2.55-bags = is a sub category of the main category above. They are vintage Chanel 2.55 bags, but I've not included 'vintage' again. 2.55 bags are a type of Chanel bag. red-2.55-classic-double-flap-bag = this is the product, the bag **1362483150 **= this is a unique id, to prevent the possibility of duplicate URLs As you no doubt can see we target, in particular, the phrase **vintage. **The actual bag / product title is: Vintage Chanel Red 2.55 classic double flap bag 10” / 25cm With this in mind, would I be better off trying to match the product name with the end of the URL as closely as possible? So a close match below would involve not repeating 'chanel' again: www.vintageheirloom.com/chanel-bags/2.55-bags/vintage-red-2.55-classic-double-flap-bag or an exact match below would involve repeating 'chanel': www.vintageheirloom.com/chanel-bags/2.55-bags/vintage-chanel-red-2.55-classic-double-flap-bag This may open up more flexibility to experiment with product terms like second hand, preowned etc. Maybe this is a bad idea as I'm removing the phrase 'vintage' from the main category. But this logical extension of this looks like keyword stuffing !! www.vintageheirloom.com/vintage-chanel-bags/vintage-2.55-bags/vintage-chanel-red-2.55-classic-double-flap-bag Maybe this is over analyzing, but I doubt it? Thanks for looking. Kevin

            Special characters in URL

            Hi There, We're in the process of changing our URL structure to be more SEO friendly. Right now I'm struggling to find a good way to handle slashes that are part of a targeted keyword. For example, if I have a product page and my product title is "1/2 ct Diamond Earrings in 14K Gold" which of the following URLs is the right way to go if I'm targeting the product title as the search keyword? example.com/jewelry/1-2-ct-diamond-earrings-in-14k-gold example.com/jewelry/12-ct-diamond-earrings-in-14k-gold example.com/jewelry/1_2-ct-diamond-earrings-in-14k-gold example.com/jewelry/1%2F2-ct-diamond-earrings-in-14k-gold Thanks!

            Is it a problem to have a homepage with a slug / URL ?

            Hi, We are designing a web site for one of our clients, and using a home made CMS. I don't know how this CMS has been built, but anyways, in the end the homepage has a URL format which looks like this : www.mydomain.com/my-custom-url.html. No www.mydomain.com. Is it dangerous for SEO to have a slug/URL directly on the homepage ? Do you have experiences, cases where it has impacted a site negatively ? The main problem I expect is duplicate content (with Google seeing both www.mydomain.com and www.mydomain.com/my-custom-url.html as being different pages) but apparently the CMS is doing a 302 redirect from the root domain to the URL (I told my colleague it should at least be a 301). Sorry if this question seems like basic SEO knowledge, but I really can't find a definitive answer on the subject. Thank you very much 🙂

            Optimal Structure for Forum Thread URL

            For getting forum threads ranked, which is best and why? site.com**/topic/**thread-title-goes-here site.com**/t/**thread-title-goes-here site.com**/**thread-title-goes-here I'd take comfort in knowing that SEOmoz uses the middle version, except that "q" is more meaningful to a human than "t".  The last option seems like the best bet overall, except that users could potentially steal urls that I may want to use in the future. My old structure was site.com/forum/topic/TOPIC_ID-thread-title-goes-here so obviously any of those would be a vast improvement, but I might as well make the best choice now so I only have to change once.

            404 errors on non-existent URLs

            Hey guys and gals, First Moz Q&A for me and really looking forward to being part of the community. I hope as my first question this isn't a stupid one but I was just struggling to find any resource that dealt with the issue and am just looking for some general advice. Basically a client has raised a problem with 404 error pages - or the lack thereof- on non-existent URLs on their site; let's say for example: 'greatbeachtowels.com/beach-towels/asdfas' Obviously content never existed on this page so its not like you're saying 'hey, sorry this isn't here anymore'; its more like- 'there was never anything here in the first place'. Currently in this fictitious example typing in 'greatbeachtowels.com/beach-towels/asdfas**'** returns the same content as the 'greatbeachtowels.com/beach-towels' page which I appreciate isn't ideal. What I was wondering is how far do you take this issue- I've seen examples here on the seomoz site where you can edit the URI in a similar manner and it returns the same content as the parent page but with the alternate address. Should 404's be added across all folders on a site in a similar way? How often would this scenario be and issue particularly for internal pages two or three clicks down? I suppose unless someone linked to a page with a misspelled URL... Also would it be worth placing 301 redirects on a small number of common mis-spellings or typos e.g. 'greatbeachtowels.com/beach-towles' to the correct URLs as opposed to just 404s? Many thanks in advance.

            Products with discrete URLs for each color

            here is the issue.  i have an ecommerce site that on a category page, shows each individual color for each product sold.  and there is a distinct URL for each color.  each product page shares the same content, with the only potentially differentiating factor being customer reviews (not nearly enough of these to differentiate anything). so we have URLs like: www.domain.com/product-green www.domain.com/product-yellow www.domain.com/product-red and so on. i am looking for a way to consolidate these URL while still showing all colors on the category page.  the first solution i am considering is using the hash tag.  so we would create www.domain.com/product#green, www.domain.com/product#yellow, www.domain.com/product#red.  if possible, i would set the canonical tag as www.domain.com/product. the second solution would be to use the canonical tag and keep the URLs as is.  the issue i see here is that we would need to create www.domain.com/product and show that page somewhere.  www.domain.com/product would the URL that the above color URLs would canonicalize to. what would be the preferred solution?  or is there something else?
