URL Injection Hack - What to do with spammy URLs that keep appearing in Google's index?
-
A website was hacked (URL injection) but the malicious code has been cleaned up and removed from all pages. However, whenever we run a site:domain.com in Google, we keep finding more spammy URLs from the hack. They all lead to a 404 error page since the hack was cleaned up in the code. We have been using the Google WMT Remove URLs tool to have these spammy URLs removed from Google's index but new URLs keep appearing every day. We looked at the cache dates on these URLs and they are vary in dates but none are recent and most are from a month ago when the initial hack occurred.
My question is...should we continue to check the index every day and keep submitting these URLs to be removed manually? Or since they all lead to a 404 page will Google eventually remove these spammy URLs from the index automatically?
Thanks in advance Moz community for your feedback.

If the urls follow any particular pattern then you can use a htaccess redirect and return the header code 410 / 403 / 404 to Google. (I suggest 410) They will soon drop out of the index.
I don't know the exact .htaccess syntax off the top of my head but it will be something like this:
If they all come from the same folder then it would look something like this:
RedirectMatch 410 ^/folder/.*$If they have a common character string after the forward slash (such as xyz) then it would look something like this:
RedirectMatch 410 ^/xyz.*$If they have any common character string footprints at all (such as xyz) then it would look something like this (now I'm guessing):
RedirectMatch 410 ^/()xyz.$This would be a pretty easy fix if all of those spammy urls have any common characters after the forward slash or they all originate from a certain folder.

You might get a little quicker removal if you send them with a 410 status code. That will let Google know that the page is gone for good. http://searchenginewatch.com/sew/how-to/2340728/matt-cutts-on-how-google-handles-404-410-status-codes

No problem at all! These new URLs do not actually exist on the website. Since we cleaned up the malicious code all of these URLs redirect to our 404 page.
-
Sorry to misunderstand the problem. Do those new urls actually exist on your site or just in search?
-
Hi 94501,
Thanks for taking the time to respond. Just to be clear, we are not submitting multiple removals for the same URL and I don't think Google WMT even allows you to do that. Completely new URLs are appearing each day after removing the older ones.
My main concern is having spammy URLs indexed and associated with my website and the negative effects it can have from an SEO perspective.

Hi Pete,
It sounds like you've done what you can. I wouldn't submit multiple removals for the same url.
I assume it's out of your site map and you're not still being hacked and have figured out how it happened and taken steps to fix it.
Google will eventually figure it out. I'd try to move on to new stuff.
Best... Mike

Forwarded vanity domains, suddenly resolving to 404 with appended URL's ending in random 5 characters
We have several vanity domains that forward to various pages on our primary domain.
Intermediate & Advanced SEO | | SS.Digital
e.g. www.vanity.com (301)--> www.mydomain.com/sub-page (200) These forwards have been in place for months or even years and have worked fine. As of yesterday, we have seen the following problem. We have made no changes in the forwarding settings. Now, inconsistently, they sometimes resolve and sometimes they do not. When we load the vanity URL with Chrome Dev Tools (Network Pane) open, it shows the following redirect chains, where xxxxx represents a random 5 character string of lower and upper case letters. (e.g. VGuTD) EXAMPLE:
www.vanity.com (302, Found) -->
www.vanity.com/xxxxx (302, Found) -->
www.vanity.com/xxxxx (302, Found) -->
www.vanity.com/xxxxx/xxxxx (302, Found) -->
www.mydomain.com/sub-page/xxxxx (404, Not Found) This is just one example, the amount of redirects, vary wildly. Sometimes there is only 1 redirect, sometimes there are as many as 5. Sometimes the request will ultimately resolve on the correct mydomain.com/sub-page, but usually it does not (as in the example above). We have cross-checked across every browser, device, private/non-private, cookies cleared, on and off of our network etc... This leads us to believe that it is not at the device or host level. Our Registrar is Godaddy. They have not encountered this issue before, and have no idea what this 5 character string is from. I tend to believe them because per our analytics, we have determined that this problem only started yesterday. Our primary question is, has anybody else encountered this problem either in the last couple days, or at any time in the past? We have come up with a solution that works to alleviate the problem, but to implement it across hundreds of vanity domains will take us an inordinate amount of time. Really hoping to fix the cause of the problem instead of just treating the symptom.0 -
Should I Add Location to ALL of My Client's URLs?
Hi Mozzers, My first Moz post! Yay! I'm excited to join the squad 🙂 My client is a full service entertainment company serving the Washington DC Metro area (DC, MD & VA) and offers a host of services for those wishing to throw events/parties. Think DJs for weddings, cool photo booths, ballroom lighting etc. I'm wondering what the right URL structure should be. I've noticed that some of our competitors do put DC area keywords in their URLs, but with the moves of SERPs to focus a lot more on quality over keyword density, I'm wondering if we should focus on location based keywords in traditional areas on page (e.g. title tags, headers, metas, content etc) instead of having keywords in the URLs alongside the traditional areas I just mentioned. So, on every product related page should we do something like: example.com/weddings/planners-washington-dc-md-va
Intermediate & Advanced SEO | | pdrama231
example.com/weddings/djs-washington-dc-md-va
example.com/weddings/ballroom-lighting-washington-dc-md-va OR example.com/weddings/planners
example.com/weddings/djs
example.com/weddings/ballroom-lighting In both cases, we'd put the necessary location based keywords in the proper places on-page. If we follow the location-in-URL tactic, we'd use DC area terms in all subsequent product page URLs as well. Essentially, every page outside of the home page would have a location in it. Thoughts? Thank you!!0 -
Should I include URLs that are 301'd or only include 200 status URLs in my sitemap.xml?
I'm not sure if I should be including old URLs (content) that are being redirected (301) to new URLs (content) in my sitemap.xml. Does anyone know if it is best to include or leave out 301ed URLs in a xml sitemap?

How to de-index old URLs after redesigning the website?
Thank you for reading. After redesigning my website (5 months ago) in my crawl reports (Moz, Search Console) I still get tons of 404 pages which all seems to be the URLs from my previous website (same root domain). It would be nonsense to 301 redirect them as there are to many URLs. (or would it be nonsense?) What is the best way to deal with this issue?

Best way to permanently remove URLs from the Google index?
We have several subdomains we use for testing applications. Even if we block with robots.txt, these subdomains still appear to get indexed (though they show as blocked by robots.txt. I've claimed these subdomains and requested permanent removal, but it appears that after a certain time period (6 months)? Google will re-index (and mark them as blocked by robots.txt). What is the best way to permanently remove these from the index? We can't use login to block because our clients want to be able to view these applications without needing to login. What is the next best solution?

Indexed Pages in Google, How do I find Out?
Is there a way to get a list of pages that google has indexed? Is there some software that can do this? I do not have access to webmaster tools, so hoping there is another way to do this. Would be great if I could also see if the indexed page is a 404 or other Thanks for your help, sorry if its basic question 😞

Posing QU's on Google Variables "aclk", "gclid" "cd", "/aclk" "/search", "/url" etc
I've been doing a bit of stats research prompted by read the recent ranking blog http://www.seomoz.org/blog/gettings-rankings-into-ga-using-custom-variables There are a few things that have come up in my research that I'd like to clear up. The below analysis has been done on my "conversions". 1/. What does "/aclk" mean in the Referrer URL? I have noticed a strong correlation between this and "gclid" in the landing page variable. Does it mean "ad click" ?? Although they seem to "closely" correlate they don't exactly, so when I have /aclk in the referrer Url MOSTLY I have gclid in the landing page URL. BUT not always, and the same applies vice versa. It's pretty vital that I know what is the best way to monitor adwords PPC, so what is the best variable to go on? - Currently I am using "gclid", but I have about 25% extra referral URL's with /aclk in that dont have "gclid" in - so am I underestimating my number of PPC conversions? 2/. The use of the variable "cd" is great, but it is not always present. I have noticed that 99% of my google "Referrer URL's" either start with:
Intermediate & Advanced SEO | | James77
/aclk - No cd value
/search - No cd value
/url - Always contains the cd variable. What do I make of this?? Thanks for the help in advance!0
