Is 404'ing a page enough to remove it from Google's index?
-
We set some pages to 404 status about 7 months ago, but they are still showing in Google's index (as 404's). Is there anything else I need to do to remove these?
-
Nice information John. I hadn't thought of adding a temporary page with a noindex tag but that sounds like a way to go for faster results.
I know Google has automatically removed 404 pages in the past. I noticed the issue Michelle is sharing and the information you shared offers great details on the process.

Setting pages to 404 should be enough to remove them after Google indexes your page enough times. Google has to be careful about this, because when many sites crash or have site maintenance, they return 404 instead of 503, so Google wouldn't want to remove pages from their index until they're sure the page is gone.
Google talks about removing pages from there index here. The Google Webmaster Tools URL removal tool is only intended for pages that urgently need to be removed, so I wouldn't recommend that. Google recommends:
- If the page no longer exists, make sure that the server returns a 404 (Not Found) or 410 (Gone) HTTP status code. This will tell Google that the page is gone and that it should no longer appear in search results.
- If the page still exists but you don't want it to appear in search results, use robots.txt to prevent Google from crawling it. Note that in general, even if a URL is disallowed by robots.txt we may still index the page if we find its URL on another site. However, Google won't index the page if it's blocked in robots.txt and there's an active removal request for the page.
- Alternatively, you can use a noindex meta tag. When we see this tag on a page, Google will completely drop the page from our search results, even if other pages link to it. This is a good solution if you don't have direct access to the site server. (You will need to be able to edit the HTML source of the page).
Is there a reason you are 404'ing these pages rather than redirecting them? If these pages have new pages with similar content, you should do a 301 redirect to keep the link juice flowing and to take advantage of these pages being linked to. If you do continue returning 404 for these pages (or even if you don't...), make sure your 404 page is a useful one, that helps users find the page they're looking for (Google help article).
Also, Ryan, I'd be interested in hearing the results of using the 410 status code. I would imagine that status code would do the trick! I'm surprised I haven't read about this more, or why it's not mentioned in the help file linked to above.

I have experienced this same issue with Google.
I just began a test by making a change on my site to one of the URLs. I am bookmarking this Q&A and will try to remember to update it if I see a change. It can take Google some time to check any individual link so it could take weeks.
In case you are curious, I have added a 410 status code for one of the pages involved. 410 means the resource is gone, while 404 is simply not found. Perhaps the 410 header code will send the right message to Google.

How will changing my website's page content affect SEO?
Our company is looking to update the content on our existing web pages and I am curious what the best way to roll out these changes are in order to maintain good SEO rankings for certain pages. The infrastructure of the site will not be modified except for maybe adding a couple new pages, but existing domains will stay the same. If the domains are staying the same does it really matter if I just updated 1 page every week or so, versus updating them all at once? Just looking for some insight into how freshening up the content on the back end pages could potentially hurt SEO rankings initially. Thanks!

Online Coupons and Shopping Savings for Automotix. Coupon codes for online discounts on Vehicles & Parts products. This is because I recently changed my program to redirect all urls with uppercase in them to lower case, as it appears that all lowercase is strongly recommended. I assume that having 2 indexed urls for the same content dilutes link juice. Can I safely remove all of my UpperCase indexed pages from Google without it affecting the indexing of the lower case urls? And if, so what is the best way -- there are thousands.0 -
Should you allow an auto dealer's inventory to be indexed?
Due to the way most auto dealership website populate inventory pages, should you allow inventory to be indexed at all? The main benefit us more content. The problem is it creates duplicate, or near duplicate content. It also creates a ton of crawl errors since the turnover is so short and fast. I would love some help on this. Thanks!

Dev Subdomain Pages Indexed - How to Remove
I own a website (domain.com) and used the subdomain "dev.domain.com" while adding a new section to the site (as a development link). I forgot to block the dev.domain.com in my robots file, and google indexed all of the dev pages (around 100 of them). I blocked the site (dev.domain.com) in robots, and then proceeded to just delete the entire subdomain altogether. It's been about a week now and I still see the subdomain pages indexed on Google. How do I get these pages removed from Google? Are they causing duplicate content/title issues, or does Google know that it's a development subdomain and it's just taking time for them to recognize that I deleted it already?

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...

Do you add 404 page into robot file or just add no index tag?
Hi, got different opinion on this so i wanted to double check with your comment is. We've got /404.html page and I was wondering if you would add this page to robot text so it wouldn't be indexed or would you just add no index tag? What would be the best approach? Thanks!

Does Google index url with hashtags?
We are setting up some Jquery tabs in a page that will produce the same url with hashtags. For example: index.php#aboutus, index.php#ourguarantee, etc. We don't want that content to be crawled as we'd like to prevent duplicate content. Does Google normally crawl such urls or does it just ignore them? Thanks in advance.

Culling 99% of a website's pages. Will this cause irreparable damage?
I have a large travel site that has over 140,000 pages. The problem I have is that the majority of pages are filled with dupe content. When Panda came in, our rankings were obliterated, so I am trying to isolate the unique content on the site and go forward with that. The problem is, the site has been going for over 10 years, with every man and his dog copying content from it. It seems that our travel guides have been largely left untouched and are the only unique content that I can find. We have 1000 travel guides in total. My first question is, would reducing 140,000 pages to just 1,000 ruin the site's authority in any way? The site does use internal linking within these pages, so culling them will remove thousands of internal links throughout the site. Also, am I right in saying that the link juice should now move to the more important pages with unique content, if redirects are set up correctly? And finally, how would you go about redirecting all theses pages? I will be culling a huge amount of hotel pages, would you consider redirecting all of these to the generic hotels page of the site? Thanks for your time, I know this is quite a long one, Nick
