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.

Mass URL changes and redirecting those old URLS to the new. What is SEO Risk and best practices?
Hello good people of the MOZ community, I am looking to do a mass edit of URLS on content pages within our sites. The way these were initially setup was to be unique by having the date in the URL which was a few years ago and can make evergreen content now seem dated. The new URLS would follow a better folder path style naming convention and would be way better URLS overall. Some examples of the **old **URLS would be https://www.inlineskates.com/Buying-Guide-for-Inline-Skates/buying-guide-9-17-2012,default,pg.html

https://www.inlineskates.com/Learn/Buying-Guide-for-Inline-Hockey-Skates,default,pg.html
https://www.inlineskates.com/Learn/Buying-Guide-for-Aggressive-Skates,default,pg.html My worry is that we do rank fairly well organically for some of the content and don't want to anger the google machine. The way I would be doing the process would be to edit the URLS to the new layout, then do the redirect for them and push live. Is there a great SEO risk to doing this?
Is there a way to do a mass "Fetch as googlebot" to reindex these if I do say 50 a day? I only see the ability to do 1 URL at a time in the webmaster backend.
Is there anything else I am missing? I believe this change would overall be good in the long run but do not want to take a huge hit initially by doing something incorrectly. This would be done on 5- to a couple hundred links across various sites I manage. Thanks in advance,

Why is this SERP displaying an incorrect URL for my homepage?
The full URL of a particular site's homepage is something like http://www.example.com/directory/.
Intermediate & Advanced SEO | | TheEspresseo
The canonical and og URLs match.
The root domain 301 redirects to it using the absolute path. And yet the SERP (and the cached version of the page) lists it simply as http://www.example.com/. What gives? Could the problem be found at some deeper technical level (.htaccess or DirectoryIndex or something?) We fiddled with things a bit this week, and while our most recent changes appear to have been crawled (and cached), I am wondering whether I should give it some more time before I proceed as if the SERP won't ever reflect the correct URL. If so, how long? [EDIT: From the comments, see here: https://www.youtube.com/watch?v=z8QKIweOzH4#t=2838]0 -

301 Redirection and apostrophes in URLs
Hi I am experiencing trouble getting any redirects with apostrophes in the URLs to 301 redirect in order to eliminate 404 errors. I have tried replacing the instance of the apostrophe in the source URL field to %27 and variations of this but to no avail. The site is a wordpress site (the old URLS are legacies from the old Business Catalyst site) and I am using the redirection plug in. I have gone into some detail with a helpful soul here http://wordpress.org/support/topic/how-to-deal-with-apostrophes-in-source-url but unfortunately to no result. If anyone has any idea how to solve this puzzle I would be grateful for the help.

Overly-Dynamic URL
Hi, We have over 5000 pages showing under Overly-Dynamic URL error Our ecommerce site uses Ajax and we have several different filters like, Size, Color, Brand and we therefor have many different urls like, http://www.dellamoda.com/Designer-Pumps.html?sort=price&sort_direction=1&use_selected_filter=Y http://www.dellamoda.com/Designer-Accessories.html?sort=title&use_selected_filter=Y&view=all http://www.dellamoda.com/designer-handbags.html?use_selected_filter=Y&option=manufacturer%3A&page3 Could we use the robots.txt file to disallow these from showing as duplicate content? and do we need to put the whole url in there? like: Disallow: /*?sort=price&sort_direction=1&use_selected_filter=Y if not how far into the url should be disallowed? So far we have added the following to our robots,txt Disallow: /?sort=title Disallow: /?use_selected_filter=Y Disallow: /?sort=price Disallow: /?clearall=Y Just not sure if they are correct. Any help would be greatly appreciated. Thank you,Kami

Is it safe to redirect multiple URLs to a single URL?
Hi, I have an old Wordress website with about 300-400 original pages of content on it. All relating to my company's industry: travel in Africa. It's a legitimate site with travel stories, photos, advice etc. Nothing spammy about. No adverts on it. No affiliates. The site hasn't been updated for a couple of years and we no longer have a need for it. Many of the stories on it are quite out of date. The site has built up a modest Mozrank value over the last 5 years, and has a few hundreds organically achieved inbound links. Recently I set up a swanky new branded website on ExpressionEngine on a new domain. My intention is to: Shut down the old site Focus all attention on building up content on the new website Ask the people linking to the old site to my new site instead (I wonder how many will actually do so...) Where possible, setup a 301 redirect from pages on the old site to their closest match on the new site Setup a 301 redirect from the old site's home page to new site's homepage Sounds good, right? But there is one issue I need some advice on... The old site has about 100 pages that do not have a good match on the new site. These pages are outdated or inferior quality, so it doesn't really make sense to rewrite them and put them on the new site. I call these my "black sheep pages". So... for these "black sheep pages" should I (A) redirect the urls to the new site's homepage (B) redirect the urls the old site's home page (which in turn, redirects to the new site's homepage, or (C) not redirect the urls, and let them die a lonely 404 death? OPTION A: oldsite.com/page1.php -> newsite.com
Intermediate & Advanced SEO | | AndreVanKets
oldsite.com/page2.php -> newsite.com
oldsite.com/page3.php -> newsite.com
oldsite.com/page4.php -> newsite.com
oldsite.com/page5.php -> newsite.com
oldsite.com -> newsite.com OPTION B: oldsite.com/page1.php -> oldsite.com
oldsite.com/page2.php -> oldsite.com
oldsite.com/page3.php -> oldsite.com
oldsite.com/page4.php -> oldsite.com
oldsite.com/page5.php -> oldsite.com
oldsite.com -> newsite.com OPTION 😄 oldsite.com/page1.php : do not redirect, let page 404 and disappear forever
oldsite.com/page2.php : do not redirect, let page 404 and disappear forever
oldsite.com/page3.php : do not redirect, let page 404 and disappear forever
oldsite.com/page4.php : do not redirect, let page 404 and disappear forever
oldsite.com/page5.php : do not redirect, let page 404 and disappear forever
oldsite.com -> newsite.com My intuition tells me that Option A would pass the most "link juice" to my new site, but I am concerned that it could also be seen by Google as a spammy redirect technique. What would you do? Help 😐1 -

Htaccess Redirect with %C2%A0 in URL
Below is my setup for redirects in .htaccess file in my root word press installation. The www to non-www works well, so no problems there Other page redirects work well, too (example: redirect 301 /some-page/ http://mysite.com/another-page/ (I didn't post those because I have a few too many : ) So here it goes... RewriteEngine On

As you can see I've tried using other varations of the "space" but no go. I also used a redirect in cPanel's Redirect screen; testing all the possible options + wildcard I've also tried this: http://serverfault.com/questions/201829/using-special-characters-in-apache-mod-rewrite-rule (perhaps unsuccessfully, because it caused a 500 server error and it's a different situation in my case) I also saw something here: http://www.webmasterworld.com/apache/3908682.htm but I don't know if it works and how I would implement that + do so without compromising ALL other redirects. Note: the URL displays with a space in the address bar of all major web browsers: http://mysite.com/10-college- majors/ and goes to a 404 page I have a goregous page / PR6 / high authority site linking to the URL on my site, but they copied the URL with a space somehow. I contacted the person responsible for the website and he claims it works fine (aka he didn't check it). Is there a clean way to redirect ONLY this problematic URL without compromising other redirects, etc? Any ideas would be great. I'll respond with progress. Thanks in advance. UPDATE the redirect works, and it did work. Even so, when looking at source of page linking to mine, the URL looks like this: ``` http://mysite.com/archives/10-college- majors/ Clicking the URL in Source View in FireFox takes me to ``` http://mysite.com/archives/10-college-%C2%A0majors/ none of my 301 redirects should direct there. I don't have any redirect plugins either.0
