Should I rename URLs to use hyphens instead of underscores?
-
Hello.
We are about to launch a redesigned and significantly expanded site that has traditionally used underscores as separators between words in its URLs.
Would you recommend replacing all the underscores with hyphens? That would then require many 301 redirects to maintain any links that might be out there.
Thank you!

Thank you, Nitin.

Thank you very much, Peter!

I'd tend to agree with Nakul on proceeding with caution - while Google doesn't necessarily treat "_" as a word separator, the URL is just one relatively small ranking factor. There are many risks in a site-wide 301-redirect, especially when you're redesigning. If the redesign runs into SEO trouble, you're not going to be able to separate the many changes, and that could delay fixing any problems.
The exception would be if you're planning to change a lot of the URLs anyway, as part of the redesign. Then, I'd go ahead and do it all at once. Hyphens are a nice-to-have - I'm just not sure that, practically, the risks outweigh the rewards. It does depend a lot on how you're currently ranking and whether the URLs are causing you any major headaches.

You should use a hyphen for your SEO URLs. Google treats a hyphen as a word separator, but does ****nottreat an underscore that way. Google treats underscore as a word joiner — so seo_moz is the same as seomoz to Google. In fact using dashes over underscores will have a (minor) ranking benefit.
Also Note that 301 redirects passes 90%-99% value to redirected link so earlier you do it the better.
Hope it makes sense.

Thanks, Nakul!

If you are just doing a redesign that does not entail any URL changes, I would suggest keep them as is.
On a side note, how are you ranking compared to your competition ?
You could potentially test 1-2 pages on your site, change _ to - and see if it makes any difference. And yes, you would need to do 301 redirects and that would pass most (not all) of your link juice. It can and still work fine. So before you do something like this on a large scale, test it on a small scale if you can.
It also depends on how much authority your site has in Google ? Do your breadcrumbs show up in Google SERPS ? And so on.
I hope this helps you come to the right conclusion.

After you remove a 301 redirect that Google has processed, will the new URL retain any of the link equity from the old URL?
Lets say you 301 redirect URL A to URL B, and URL A has some backlinks from other sites. Say you left the 301 redirect in place for a year, and Google had already replaced the old URL with the new URL in the SERPs, would the new URL (B) retain some of the link equity from URL A after the 301 redirect was removed, or does the redirect have to remain in place forever?

301 Redirect Attribute-Based Dynamic URL to Renamed Attributes
I work with a number of ecommerce sites that have dynamically-created urls based off of product attributes we've assigned in our cms. I am updating a handful of these attributes to more seo-friendly terms because they are outdated but am not certain how to go about redirecting all the urls that each attribute is in/could be in. For example: If I had the attributes hoagie and beanie and changed them to sandwich and headwear, a dynamic url might change like this: .com/hoagie/french-bread ---> .com/sandwich/french-bread .com/beanie/hoagie/novelty ----> .com/headwear/sandwich/novelty Since the urls are dynamically created, I am not sure how I go about redirecting all of them, or if I need to redirect all of them at all (instead just redirecting the urls indexed by Google, etc.) I also have a number of links within copy on each of the sites that contain linked anchor text using attributes that will be changing. I am assuming I will need to 301 each of these or update them manually to reflect the new attributes. I am new to the seo field and would appreciate any and all advice or direction to guides and tutorials that could aid me with this project. Thanks!

Should I change by URL's
I started with a static website and then moved to Wordpress. At the time I had a few hundred pages and wanted to keep the same URL structure so I use a plugin that adds .html to every page. Should I change the structure to a more common URL structure and do 301 directs from the .html page to the regular page?

Using a non-visible H1
I have a developer that wants to use style="text-indent:-9999px" to make the H1 non-visible to the user. Being the conservative person I am, I've never tried this before and worry that Search Engines may think this is a form of cloaking. Am I worrying about nothing? And apologies if it's already been covered here. I couldn't find it. Thanks in advance!!!!

Using the Canonical Tag
Hi, I have an issue that can be solve with a canonical tag, but I am not sure yet, we are developing a page full of statistics, like this: www.url.com/stats/ But filled with hundreds of stats, so users can come and select only the stats they want to see and share with their friends, so it becomes like a new page with their slected stats: www.url.com/stats/?id=mystats The problems I see on this is: All pages will be have a part of the content from the main page 1) and many of them will be exactly the same, so: duplicate content. My idea was to add the canonical tag of "www.url.com/stats/" to all pages, similar as how Rand does it here: http://www.seomoz.org/blog/canonical-url-tag-the-most-important-advancement-in-seo-practices-since-sitemaps But I am not sure of this solution because the content is not exactly the same, page 2) will only have a part of the content that page 1) has, and in some cases just a very small part. Is the canonical tag useful in this case? Thank you!
