Product sorting and dynamic urls
-
On our weekly SEOmoz crawls, we get thousands of warnings about overly dynamic URLs as a result of our product sorting options at the top of our category pages. It seems like the ability to sort products by price, name, etc., is nice for the customer. For SEO is this really a problem or can we ignore these warnings?

I see, thank you.

Thank you for the details.

Thank you, I was guessing that might be the thing to do.

Yes rel canonical is an option too - BUT please be sure to do it correctly if you have pagination. Don't point page 2, page 3 etc back at page 1...
So you should end up with canonical's like this:
or
or
etc

James is absolutely correct.This is a SEO issue, and you do need to address it. I would like to add a bit more clarification.
Let's say you have a page that shows sweaters. You can sort that page by the metrics you indicated. When that happens you have various pages as follows:
mysite.com/sweaters?sort=price&dir=asc
mysite.com/sweaters?sort=price&dir=desc
mysite.com/sweaters?sort=name&dir=asc
If you have no sort options, then you have 1 sweater page. If you have 7 sort options, you have 15 sweater pages. Which one should google index? Customer #1 links to the page sorted by price, meanwhile customer #2 links to the page sorted alphabetically. Google doesn't know what to do...unless you tell them.
All the various pages should be canonicalized. Each of these pages should contain a line of code in their header similar to:
That tag tells search engines that the original URL is the one you wish indexed in search engines, and that all the various pages offering different sort orders are copies of the original page.

Yes, you should fix it. Make sure that only one version of that page is indexed - presumably the one that a user first sees before sorting/filtering/etc. When I say one version though, I really mean one version for each category, and don't forget paging - let the SE's index each page.
Just hide all the sorting/filtering versions, the best method is to add a noindex, follow meta tag

Changing Url structure to incorporate Woo Commerce
Advise needed please We have rankings coming along nicely with a website that uses page content but we now need to start online shopping with woo commerce The url structure has always been a bit of a mess, but its quite in depth We are looking to move small paragraphs about each product cat (formerly put on Pages) information into the Product Category and then the Product information into the product page and redirect the old urls to the new urls. It would mean updating the permalinks also - My concern if there is less leverage with product categories - do these rank just as well as pages, are we going to see our rankings change dramatically in doing so? Added to that - is it best doing this change gradually or all at once (like staging site to get the set up ready) and then pushing live

Dynamic URL Parameters + Woocommerce create 404 errors
Hi Guys,
On-Page Optimization | | jeeyer
Our latest Moz crawl shows a lot of 404-errors for pages that create dynamical links for users? (I guess it are dynamic links, not sure). Situation: On a page which shows products from brand X users can use the pagination icons on the bottom, or click on: View: / 24/48/All.
When a user clicks 48 the end of the link will be /?show_products=48
I think there were some pages that could show 48 products but do not exist anymore (because products are sold out for example), and that's why they show 404's and Moz reports them. How do I deal with these 404-errors? I can't set a 301-redirect because it depends on how many products are shown (it changes every time).
Should I just ignore these kind of 404-errors? Or what is the best way to handle this situation?0 -

What are the benefits of the URL meta tag?
We have too many meta tags and want to get rid of all the outdated ones. However, we don't want to eliminate valuable meta tags by mistake. So, before we say goodbye to the URL meta tag, we want to make sure we understand the pros and cons, if any. By the way, we are not referring to canonical URL tags, just URL as in:

URL length... is >115 now >255?
I've been having detailed discussions with a CMS provider on behalf of a client. Long URLs are the least of their problems however, the developer is arguing that Google has amended their algorithm and will now read URLs that are up to 255 characters long. I have stated that as far as I am aware, Google will still not read URLs over 115 characters... Before I stamp my feet, can someone confirm what is actually happening? SEOmoz still classes URLs >115 characters long as an amber issue. Thanks

URL Rewrite
(By Google Traductor) Hello, I wanted to ask about some changes that we are evaluating for the issue of passing the url with variables to be more descriptive, for example: http://www.agroads.com.ar/detalle.asp?clasi=139592 tohttp://www.agroads.com.ar/humedimetro-para-cereales-draminski-gmm-139592.html In this case corresponds to the breakdown of a product if you have long published andcan be well positioned to change the title of this position would be lost unless youmanage it with a 301, as one would manage when you have more than 30000 products and title may change several times? There are tools to manage this? Finally, we must apply this to all listed with their respective filters, recommends doingtheir part with 301 redirects and analyze what funciene well to continue with the rest or implement a complete change? I hope I can bring a little light to implement this. Greetings and thanks! Roberto

Unique Product Descriptions Vs. Speedy Launch
We are close to launching a new property and are also in the process of writing completely unique product descriptions for every product. This will continue to take a lot of time. We are debating the following two options: A. Launch soon with about 10-15% of descriptions being very unique and the rest being standard (mostly manufacture supplied). Then continue to update product content as we complete new fresh descriptions. B. Wait to launch until everything is unique. This will probably set us back 2 Months. We of course would like to go live sooner than later, but don't want to jeopardize anything as it pertains to rankings. The fear internally with launching now is that product pages get crawled, but don't make our best 1st impression with the engines. The counter argument is that it doesn't matter much, pages will get crawled again, and the fresh new content will be considered. Any inputs on this? Is '1st impression' with Google key, or is there no harm in launching and updating. Everything else is very sound -- architecture, on-site optimization, usability/crawlability etc. It's just the matter of the unique vs. generic product page content. Many thanks!

Attributes vs. Separate Products?
I carry a line of products that come in 4 sizes and 15 colors. Is it better to have separate products for each combination (Red Large, Blue Small, etc), or a product for each size with attributes for the color, or something else? Also, should I put the brand name in each product name, or only put it in the category that contains that brand? Thanks.
