Attack of the dummy urls -- what to do?
-
It occurs to me that a malicious program could set up thousands of links to dummy pages on a website:
www.mysite.com/dynamicpage/dummy123
www.mysite.com/dynamicpage/dummy456
etc..
How is this normally handled? Does a developer have to look at all the parameters to see if they are valid and if not, automatically create a 301 redirect or 404 not found? This requires a table lookup of acceptable url parameters for all new visitors.
I was thinking that bad url names would be rare so it would be ok to just stop the program with a message, until I realized someone could intentionally set up links to non existent pages on a site.

Hello,
I am also having this issue with hundreds of dummy urls that never existed as a part of our website's blog. Do I go into parameters and specify each of the dummy urls to avoid this?
Thanks in advance for any help!!!! (and sorry to piggyback this question Theodore-hope you don't mind!)

Thanks Ray. Appreciate the advice!

It's great that you've identified issues like this. I also suggest that if you know certain parameters are generated often and not necessary to index, that you go into your Google Webmaster Tools account > Crawl > URL Parameters and proactively set the crawl rate to 'No URLs' is appropriate. I do this with certain custom parameters for sites that are prone to having these extra URLs indexed mistakenly.

Hi Ray-pp,
Thanks for your answer. I'm not getting anything significant, but occasionally a bot will come with extra stuff added to the parameter names, so it got me to thinking a malicious program or nasty competitor might want to do that to cause havoc. My understanding is that 404s don't hurt SEO ranking from Google, but I was thinking that the way things are set up now no-one would get a 404 and in fact Google would index the 'bad' pages, so maybe I needed to do something proactively to 404 or 301 such pages so they would never get put into an index at all.
Since my site has lots of dynamically generated pages, I've had my share of surprises, and am just trying to avoid any new ones!

Hi Theodore - You pose an interesting problem, are you currently experiencing this issue? I don't see why someone would create a bunch of random non-existent links to your site, but if they did (and the pages were receiving low quality traffic) then I would proactively disavow those domains that created the links. That would be enough to prevent any penalties you're afraid of receiving.
If, however, you're noticing that specific 404 pages are receiving quality traffic (maybe an old page was removed but good traffic is still sent to the page) then you would want to 301 that page to its closest relative page that deserves the traffic and authority.
Does that help? Maybe a little more information around you specific problem would allow me to tailor the advice better.

Help with facet URLs in Magento
Hi Guys, Wondering if I can get some technical help here... We have our site britishbraces.co.uk , built in Magento. As per eCommerce sites, we have paginated pages throughout. These have rel=next/prev implemented but not correctly ( as it is not in is it in ) - this fix is in process. Our canonicals are currently incorrect as far as I believe, as even when content is filtered, the canonical takes you back to the first page URL. For example, http://www.britishbraces.co.uk/braces/x-style.html?ajaxcatalog=true&brand=380&max=51.19&min=31.19 Canonical to... http://www.britishbraces.co.uk/braces/x-style.html Which I understand to be incorrect. As I want the coloured filtered pages to be indexed ( due to search volume for colour related queries ), but I don't want the price filtered pages to be indexed - I am unsure how to implement the solution? As I understand, because rel=next/prev implemented ( with no View All page ), the rel=canonical is not necessary as Google understands page 1 is the first page in the series. Therefore, once a user has filtered by colour, there should then be a canonical pointing to the coloured filter URL? ( e.g. /product/black ) But when a user filters by price, there should be noindex on those URLs ? Or can this be blocked in robots.txt prior? My head is a little confused here and I know we have an issue because our amount of indexed pages is increasing day by day but to no solution of the facet urls. Can anybody help - apologies in advance if I have confused the matter. Thanks

URL structure change and xml sitemap
At the end of April we changed the url structure of most of our pages and 301 redirected the old pages to the new ones. The xml sitemaps were also updated at that point to reflect the new url structure. Since then Google has not indexed the new urls from our xml sitemaps and I am unsure of why. We are at 4 weeks since the change, so I would have thought they would have indexed the pages by now. Any ideas on what I should check to make sure pages are indexed?

Weird 404 URL Problem - domain name being placed at end of urls
Hey there. For some reason when doing crawl tests I'm finding pages with the domain name being tacked on the end and causing 404 errors.

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.

Is using dots in URL path really a problem?
we have a couple of pages displaying a dot in the URL path like domain.com/mr.smith/widget-mr.smith It displays fine in chrome, firefox and IE and for the user it may actually look better than replacing it by _ or -. Did this ever cause problems to anybody?

Any statement from google about it?
Should I change existing URLs? If so, which other characters can I use in the URL instead of underscore and dash, since in our system dash and underscore are already used for rewriting other characters. Thanks0 -
How to deal with old, indexed hashbang URLs?
I inherited a site that used to be in Flash and used hashbang URLs (i.e. www.example.com/#!page-name-here). We're now off of Flash and have a "normal" URL structure that looks something like this: www.example.com/page-name-here Here's the problem: Google still has thousands of the old hashbang (#!) URLs in its index. These URLs still work because the web server doesn't actually read anything that comes after the hash. So, when the web server sees this URL www.example.com/#!page-name-here, it basically renders this page www.example.com/# while keeping the full URL structure intact (www.example.com/#!page-name-here). Hopefully, that makes sense. So, in Google you'll see this URL indexed (www.example.com/#!page-name-here), but if you click it you essentially are taken to our homepage content (even though the URL isn't exactly the canonical homepage URL...which s/b www.example.com/). My big fear here is a duplicate content penalty for our homepage. Essentially, I'm afraid that Google is seeing thousands of versions of our homepage. Even though the hashbang URLs are different, the content (ie. title, meta descrip, page content) is exactly the same for all of them. Obviously, this is a typical SEO no-no. And, I've recently seen the homepage drop like a rock for a search of our brand name which has ranked #1 for months. Now, admittedly we've made a bunch of changes during this whole site migration, but this #! URL problem just bothers me. I think it could be a major cause of our homepage tanking for brand queries. So, why not just 301 redirect all of the #! URLs? Well, the server won't accept traditional 301s for the #! URLs because the # seems to screw everything up (server doesn't acknowledge what comes after the #). I "think" our only option here is to try and add some 301 redirects via Javascript. Yeah, I know that spiders have a love/hate (well, mostly hate) relationship w/ Javascript, but I think that's our only resort.....unless, someone here has a better way? If you've dealt with hashbang URLs before, I'd LOVE to hear your advice on how to deal w/ this issue. Best, -G

Magento: URLs for Products in Multiple Categories
I am working in Magento to build out a large e-commerce site with several thousand products. It's a great platform, but I have run into the issue of what it does to URLs when you put a product into multiple categories. Basically, "a book" in two categories would make two URLs for one product: 1) /books/a-book 2) author-name/a-book So, I need to come up with a solution for this. It seems I have two options: Found this from a Magento SEO article: 'Magento gives you the ability to add the name of categories to path for product URL's. Because Magento doesn't support this functionality very well - it creates duplicate content issues - it is a very good idea to disable this. To do this, go to System => Configuration => Catalog => Search Engine Optimization and set "Use categories path for product URL's to "no".' This would solve the issues and be a quick fix, but I think it's a double edged sword, because then we lose the SEO value of our well named categories being in the URL. Use Canonical tags. To be fair, I'm not even sure this is possible. Even though it is creating different URLs and, thus, poses a risk of "duplicate content" being crawled, there really is only one page on the admin side. So, I can't go to all of the "duplicate" pages and put a canonical tag, because those duplicate pages don't really exist on the back-end. Does that make sense? After typing this out, it seems like the best thing to do probably will be to just turn off categories in the URL from the admin side. However, I'd still love any input from the community on this. Thanks!

Blocking Dynamic URLs with Robots.txt
Background: My e-commerce site uses a lot of layered navigation and sorting links. While this is great for users, it ends up in a lot of URL variations of the same page being crawled by Google. For example, a standard category page: www.mysite.com/widgets.html ...which uses a "Price" layered navigation sidebar to filter products based on price also produces the following URLs which link to the same page: http://www.mysite.com/widgets.html?price=1%2C250 http://www.mysite.com/widgets.html?price=2%2C250 http://www.mysite.com/widgets.html?price=3%2C250 As there are literally thousands of these URL variations being indexed, so I'd like to use Robots.txt to disallow these variations. Question: Is this a wise thing to do? Or does Google take into account layered navigation links by default, and I don't need to worry. To implement, I was going to do the following in Robots.txt: User-agent: * Disallow: /*? Disallow: /*= ....which would prevent any dynamic URL with a '?" or '=' from being indexed. Is there a better way to do this, or is this a good solution? Thank you!
