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

Does Google ignore content styled with 'display:none'?
Do you know if an H1 within a div that has a 'display: none' style applied will still be crawled and evaluated by Google? We have that situation on this page on line 136: view-source:https://www.junk-king.com/services/items-we-take/foreclosure-cleanouts Of course we also have an H1 up at the top of the page and are concerned that the second one will cause interference with our SEO efforts. I've seen conflicting and inconclusive information on line - not sure. Thanks for any help.

Magento: Should we disable old URL's or delete the page altogether
Our developer tells us that we have a lot of 404 pages that are being included in our sitemap and the reason for this is because we have put 301 redirects on the old pages to new pages. We're using Magento and our current process is to simply disable, which then makes it a a 404. We then redirect this page using a 301 redirect to a new relevant page. The reason for redirecting these pages is because the old pages are still being indexed in Google. I understand 404 pages will eventually drop out of Google's index, but was wondering if we were somehow preventing them dropping out of the index by redirecting the URL's, causing the 404 pages to be added to the sitemap. My questions are: 1. Could we simply delete the entire unwanted page, so that it returns a 404 and drops out of Google's index altogether? 2. Because the 404 pages are in the sitemap, does this mean they will continue to be indexed by Google?

How can I get a list of every url of a site in Google's index?
I work on a site that has almost 20,000 urls in its site map. Google WMT claims 28,000 indexed and a search on Google shows 33,000. I'd like to find what the difference is. Is there a way to get an excel sheet with every url Google has indexed for a site? Thanks... Mike

Why are bit.ly links being indexed and ranked by Google?
I did a quick search for "site:bit.ly" and it returns more than 10 million results. Given that bit.ly links are 301 redirects, why are they being indexed in Google and ranked according to their destination? I'm working on a similar project to bit.ly and I want to make sure I don't run into the same problem.

After reading of Google's so called "over-optimization" penalty, is there a penalty for changing title tags too frequently?
In other words, does title tag change frequency hurt SEO ? After changing my title tags, I have noticed a steep decline in impressions, but an increase in CTR and rankings. I'd like to once again change the title tags to try and regain impressions. Is there any penalty for changing title tags too often? From SEO forums online, there seems to be a bit of confusion on this subject...

How is Google crawling and indexing this directory listing?
We have three Directory Listing pages that are being indexed by Google: http://www.ccisolutions.com/StoreFront/jsp/ http://www.ccisolutions.com/StoreFront/jsp/html/ http://www.ccisolutions.com/StoreFront/jsp/pdf/ How and why is Googlebot crawling and indexing these pages? Nothing else links to them (although the /jsp.html/ and /jsp/pdf/ both link back to /jsp/). They aren't disallowed in our robots.txt file and I understand that this could be why. If we add them to our robots.txt file and disallow, will this prevent Googlebot from crawling and indexing those Directory Listing pages without prohibiting them from crawling and indexing the content that resides there which is used to populate pages on our site? Having these pages indexed in Google is causing a myriad of issues, not the least of which is duplicate content. For example, this file <tt>CCI-SALES-STAFF.HTML</tt> (which appears on this Directory Listing referenced above - http://www.ccisolutions.com/StoreFront/jsp/html/) clicks through to this Web page: http://www.ccisolutions.com/StoreFront/jsp/html/CCI-SALES-STAFF.HTML This page is indexed in Google and we don't want it to be. But so is the actual page where we intended the content contained in that file to display: http://www.ccisolutions.com/StoreFront/category/meet-our-sales-staff As you can see, this results in duplicate content problems. Is there a way to disallow Googlebot from crawling that Directory Listing page, and, provided that we have this URL in our sitemap: http://www.ccisolutions.com/StoreFront/category/meet-our-sales-staff, solve the duplicate content issue as a result? For example: Disallow: /StoreFront/jsp/ Disallow: /StoreFront/jsp/html/ Disallow: /StoreFront/jsp/pdf/ Can we do this without risking blocking Googlebot from content we do want crawled and indexed? Many thanks in advance for any and all help on this one!

Include Cross Domain Canonical URL's in Sitemap - Yes or No?
I have several sites that have cross domain canonical tags setup on similar pages. I am unsure if these pages that are canonicalized to a different domain should be included in the sitemap. My first thought is no, because I should only include pages in the sitemap that I want indexed. On the other hand, if I include ALL pages on my site in the sitemap, once Google gets to a page that has a cross domain canonical tag, I'm assuming it will just note that and determine if the canonicalized page is the better version. I have yet to see any errors in GWT about this. I have seen errors where I included a 301 redirect in my sitemap file. I suspect its ok, but to me, it seems that Google would rather not find these URL's in a sitemap, have to crawl them time and time again to determine if they are the best page, even though I'm indicating that this page has a similar page that I'd rather have indexed.

Does Google crawl the pages which are generated via the site's search box queries?
For example, if I search for an 'x' item in a site's search box and if the site displays a list of results based on the query, would that page be crawled? I am asking this question because this would be a URL that is non existent on the site and hence am confused as to whether Google bots would be able to find it.
