Rewriting dynamic urls to static
-
We're currently working on an SEO project for http://www.gear-zone.co.uk/.
After a crawl of their site, tons of duplicate content issues came up. We think this is largely down to the use of their brand filtering system, which works like this:
By clicking on a brand, the site generates a url with the brand keywords in, for example:
http://www.gear-zone.co.uk/3-season-synthetic-cid77.html
filtered by the brand Mammut becomes:
http://www.gear-zone.co.uk/3-season-synthetic-Mammut-cid77.html?filter_brand=48
This was done by a previous SEO agency in order to prevent duplicate content. We suspect that this has made the issue worse though, as by removing the dynamic string from the end of the URL, the same content is displayed as the unfiltered page.
For example
http://www.gear-zone.co.uk/3-season-synthetic-Mammut-cid77.html
shows the same content as:
http://www.gear-zone.co.uk/3-season-synthetic-cid77.html
Now, if we're right in thinking that Google is unlikely to the crawl the dynamic filter, this would seem to be the root of the duplicate issue.
If this is the case, would rewriting the dynamic URLs to static on the server side be the best fix? It's a Windows Server/asp site.
I hope that's clear! It's a pretty tricky issue and it would be good to know your thoughts.
Thanks!

I use canonical references on all my pages no matter what. Most professional sites I encounter do as well. You will notice they are used on SEOmoz.
I would use a rewrite rule mainly to do something alone the lines of directing all your non www traffic to their www counterpart. For the type of issue you are working on, I would use canonical tags on every page.

Thanks for answering so quickly. We were going to add a canonical tag as well to make sure, but I thought a rewrite might be the best bet to start with. Would you do both, or just the canonical?

Canonicalizing your pages will solve your issue.
You can have a page and present it to visitors with various URLs. What Google needs to understand is which is the primary version of the page. Using your example:
http://www.gear-zone.co.uk/3-season-synthetic-cid77.html
http://www.gear-zone.co.uk/3-season-synthetic-Mammut-cid77.html
You can put the following tag on the pages:
That tag lets Google know that you have a single page which you are presenting to visitors with different URLs. This is a very common practice. For example, you may have a product page and sort it ascending by price, descending by product name, etc. These pages all offer the same content but just presented a bit differently for your visitor's benefit.

Google Only Indexing Canonical Root URL Instead of Specified URL Parameters
We just launched a website about 1 month ago and noticed that Google was indexing, but not displaying, URLs with "?location=" parameters such as: http://www.castlemap.com/local-house-values/?location=great-falls-virginia and http://www.castlemap.com/local-house-values/?location=mclean-virginia. Instead, Google has only been displaying our root URL http://www.castlemap.com/local-house-values/ in its search results -- which we don't want as the URLs with specific locations are more important and each has its own unique list of houses for sale. We have Yoast setup with all of these ?location values added in our sitemap that has successfully been submitted to Google's Sitemaps: http://www.castlemap.com/buy-location-sitemap.xml I also tried going into the old Google Search Console and setting the "location" URL Parameter to Crawl Every URL with the Specifies Effect enabled... and I even see the two URLs I mentioned above in Google's list of Parameter Samples... but the pages are still not being added to Google. Even after Requesting Indexing again after making all of these changes a few days ago, these URLs are still displaying as Allowing Indexing, but Not On Google in the Search Console and not showing up on Google when I manually search for the entire URL. Why are these pages not showing up on Google and how can we get them to display? Only solution I can think of would be to set our main /local-house-values/ page to noindex in order to have Google favor all of our other URL parameter versions... but I'm guessing that's probably not a good solution for multiple reasons.

Trailing Slashes on URLs
Hi we currently have a site on Wordpress which has two version of each URL trailing slash on URLs and one without it. Example: www.domain.com/page (preferred version - based on link data) www.domain.com/page**/** The non-slash version of the URL has most of the external links pointing to them, so we are going to pick that as the preferred version. However, currently, each version of every URL has rel canonical tag pointing to the non-preferred version. E.g. www.domain.com/page the rel canonical tag is: www.domain.com/page/ What would be the best way to clean up this setup? Cheers.

Link juice through URL parameters
Hi guys, hope you had a fantastic bank holiday weekend. Quick question re URL parameters, I understand that links which pass through an affiliate URL parameter aren't taken into consideration when passing link juice through one site to another. However, when a link contains a tracking URL parameter (let's say gclid=), does link juice get passed through? We have a number of external links pointing to our main site, however, they are linking directly to a unique tracking parameter. I'm just curious to know about this. Thanks, Brett

URLs with parameters + canonicals + meta robots
Hi Moz community! I'm posting a new question here as I couldn't find specific answer to the case I'm facing. Along with canonical tags, we are implementing meta robots on our pages (e-commerce website with thousands of pages). Most of the cases have been covered but I still have one unanswered case: our products are linked from list pages (mostly categories) but they almost always include a tracking parameter (ie /my-product.html?ref=xxx) products urls are secured with a canonical tag (referring only to the clean url /my-product.html) but what would be the best solution regarding the meta robots? For now we opted for a meta robot 'noindex, follow' for non canonical urls (so the ones unfortunately linked from our category/list pages), but I'm afraid that it could hurt our SEO (apparently no juice is given from URLs with a noindex robots), and even maybe prevent bots from crawling our website properly ... Would it be best to have no meta robots at all on these product urls with parameters? (we obviously can't have 'index, follow' when the canonical ref points to another url!). Thanks for your help!

I get warnings for overly dynamic urls, but have canonical links in place.
Hi, Seomoz gives me warnings for overly dynamic urls. This is mostly caused by a crumbtrail system. I have a canonical link in the header for all the urls I receive warnings on, should I still worry about this? Thanks!

Page URL keywords
Hello everybody, I've read that it's important to put your keywords at the front of your page title, meta tag etc, but my question is about the page url. Say my target keywords are exotic, soap, natural, and organic. Will placing the keywords further behind the URL address affect the SEO ranking? If that's the case what's the first n number of words Google considers? For example, www.splendidshop.com/gift-set-organic-soap vs www.splendidshop.com/organic-soap-gift-set Will the first be any less effective than the second one simply because the keywords are placed behind?

Duplicate URL home page
I just got a duplicate URL error on by SEOMOZ report - and I wonder if I should worry about it Assume my site is named www.widgets.com I'm getting duplicate url from http://www.widgets.com & http://www.widgets.com/ Do the search engines really see this as different on the home page? The general drift on the web is that You site should look like Home page = http://www.widgets.com And subpages http://www.widgets.com/widget1/ Of course it seems as though the IIS7 slash tool will rewrite everything Including the home page to a slash.
