Are 404 Errors a bad thing?
-
Good Morning...
I am trying to clean up my e-commerce site and i created a lot of new categories for my parts...
I've made the old category pages (which have had their content removed) "hidden" to anyone who visits the site and starts browsing. The only way you could get to those "hidden" pages is either by knowing the URLS that I used to use or if for some reason one of them is spidering in Google.
Since I'm trying to clean up the site and get rid of any duplicate content issues, would i be better served by adding those "hidden" pages that don't have much or any content to the Robots.txt file or should i just De-activate them so now even if you type the old URL you will get a 404 page...
In this case, are 404 pages bad? You're typically not going to find those pages in the SERPS so the only way you'd land on these 404 pages is to know the old url i was using that has been disabled.
Please let me know if you guys think i should be 404'ing them or adding them to Robots.txt
Thanks

Hello Prime85,
Both these answers are correct in their own way, but let me clarify and add my 2 cents.
1. 404s don't hurt your rankings directly, but they can provide a poor user experience.
2. If you keep URLs "live" - then Google can keep these URLs in their index indefinitely. This means search engines may waste time and crawling resources visiting pages you don't want in the index, while ignoring your other pages. This CAN hurt your SEO.
Long story short, (like Brian says) if the page is no longer relevant, you should remove it from the index or redirect it to another URL.
3. Returning a 404 kills all link juice that may have gone to the page, and it can also send confusing signals to search engines about the structure of your site if you have a bunch of pages returning 404s at the same time you have a bunch of new, but similar, pages popping into existence.
The best policy is to set up a 301 redirect from your outdated pages to the most relevant new pages. Don't redirect everything to a single page like the homepage, but instead the redirect to the page that would be most relevant and useful for the user.
On the other hand, if it's a low-value page and there's really no need to redirect it, you should remove it from the index. There's a couple ways to do this:
- Put a meta robots "NOINDEX" tag in the head and wait for Google to crawl the page and process the noindex. It helps if the URL is listed in your sitemap so that they can more easily "find" the url.
- Block the URL through robots.txt, then use Google's Remove URL tool in Webmaster tools
- Return a 404, and use the Remove URL tool
Hope this helps! Best of luck with your SEO.

Hi,
Here is what google says about 404s
"Q: Do the 404 errors reported in Webmaster Tools affect my site’s ranking?
A: 404s are a perfectly normal part of the web; the Internet is always changing, new content is born, old content dies, and when it dies it (ideally) returns a 404 HTTP response code. Search engines are aware of this; we have 404 errors on our own sites, as you can see above, and we find them all over the web. In fact, we actually prefer that, when you get rid of a page on your site, you make sure that it returns a proper 404 or 410 response code (rather than a “soft 404”). "" If some URLs on your site 404, this fact alone does not hurt you or count against you in Google’s search results. However, there may be other reasons that you’d want to address certain types of 404s. For example, if some of the pages that 404 are pages you actually care about, you should look into why we’re seeing 404s when we crawl them! If you see a misspelling of a legitimate URL (www.example.com/awsome instead of www.example.com/awesome), it’s likely that someone intended to link to you and simply made a typo. Instead of returning a 404, you could 301 redirect the misspelled URL to the correct URL and capture the intended traffic from that link. You can also make sure that, when users do land on a 404 page on your site, you help them find what they were looking for rather than just saying “404 Not found."
http://googlewebmastercentral.blogspot.com/2011/05/do-404s-hurt-my-site.html
I would recommend you to 301 redirect them to the appropriated page and 404 what you dont find a good page to redirect.

Are on-site content carousel bad for SEO?
Hi, I didn't find an answer to my question in the Forum. I attached an example of content carousel, this is what I'm talking about. I understand that Google has no problem anymore with tabbed contents and accordeons (collapsible contents). But now I'm wondering about textual carousels. I'm not talking about an image slider, I'm talking about texts. Is text carousel harder to read for Google than plain text or tabs? Of course, i'm not talking about a carousel using Flash. Let's say the code is proper... Thanks for your help. spfra5

Hundreds of 404 errors are showing up for pages that never existed
For our site, Google is suddenly reporting hundreds of 404 errors, but the pages they are reporting never existed. The links Google shows are clearly spam style, but the website hasn't been hacked. This happened a few weeks ago, and after a couple days they disappeared from WMT. What's the deal? Screen-Shot-2016-02-29-at-9.35.18-AM.png

Self Referencing Links - Good or Bad?
As an agency we get quite a few of our clients come to us saying "Ooo, this company just contacted me saying they've run an SEO report on my site and we need to improve on these following things" We had one come through the other day that had reported on something we had not seen in any others before. They called them self-referencing links and marked it as a point of action should be taken. They had stated that 100% of the pages on our clients website had self-referencing links. The definition of self-referencing is when there is a link on a page that is linking to the page you are currently on. So for example you're on the home page and there is a link in the nav bar at the top that says "Home" with a link to the home page, the page you are already currently on. Is it bad practice? And if so can we do anything about it as it would seem strange from a UI point of view not to have a consistent navigation. I have not heard anything about this before but I wanted to get confirmation before going back to our client and explaining. Thanks Mozzers!

Will bad things happen if I cancel 301 site redirect?
Hi, please someone help! We have two identical websites, say A & B. Because of the not so good SEO establishment, site B was built and site A was 301 redirected to site B weeks ago. For some reasons, we have to reuse site A, which means we have to cancel the 301 redirection. (Sound a little crazy) So the question are: 1. Can we conduct the action? 2. If we cant, what's the reason? 3. If we can, what would be the best practice? Thanks for help in advance! Plus: we also CARE what would happen to site B if the 301 is cancelled? Will it grow healthy like a new site?

Is it bad (black hat) to have an H1 text as a text indent?
Is it bad practice to use a text indent through CSS for H1 text on a homepage(basically hiding h1 text)? I'm just trying to compensate for the fact that some text that should really be in the h1 tag is actually an image.

404 crawl errors from "tel:" link?
I am seeing thousands of 404 errors. Each of the urls is like this: abc.com/abc123/tel:1231231234 Everything is normal about that url except the "/tel:1231231234" these urls are bad with the tel: extension, they are good without it. The only place I can find this character string is on each page we have this code which is used for Iphones and such. What are we doing wrong? Code: Phone: <a href="[tel:1231231234](tel:7858411943)"> (123) 123-1234a>
