External 404 vs Internal 404
-
Which one is bad?
External - when someone adds an incorrect link to your site, maybe does a typo when linking to an inner page. This page never existed on your site, google shows this as a 404 in Webmaster tools.
Internal - a page existed, google indexed it, and you deleted it and didnt add a 301.
Internal ones are in the webmaster's control, and i can understand if google gets upset if it sees a 404 for a URL that existed before, however surely "externally created" 404 shoudnt cause any harm cause that page never existed. And someone has inserted an incorrect link to your site.
-
What exactly do you mean by "bad?"
They are both undesired. You certainly won't be penalized for having a 404 specifically, but you may see a decrease in ranking if it affects your site structure or if the pages you lost were passing along page authority to other pages.
You should do everything you can to limit both. Both are equally bad.
Let me know if I understood the question correctly. Cheers!

Two websites vs each other owned by same company
My client owns a brand and came to me with two ecommerce websites. One website sells his specific brand product and the other sells general products in his niche (including his branded product). Question is my client wants to rank each website for basically the same set of keywords. We have two choices I'd like feedback on- Choice 1 is to rank both websites for same keyword groupings so even if they are both on page 1 of the serps then they take up more real estate and share of voice. are there any negative possibilities here? Choice 2 is to recommend a shift in the position of the general industry website to bring it further away from the industry niche by focusing on different keywords so they don't compete with each other in the serps. I'm for choice 1, what about you?

Using Canonical URL to poin to an external page
I was wondering if I can use a canonical URL that points to a page residing on external site? So a page like:

Lowercase VS. Uppercase Canonical tags?
Hi MOZ, I was hoping that someone could help shed some light on an issue I'm having with URL structure and the canonical tag. The company I work for is a distributor of electrical products and our E-commerce site is structured so that our URL's (specifically, our product detail page URL's) include a portion (the part #) that is all uppercase (e.g: buy/OEL-Worldwide-Industries/AFW-PG-10-10). The issue is that we have just recently included a canonical tag in all of our product detail pages and the programmer that worked on this project has every canonical tag in lowercase instead of uppercase. Now, in GWT, I'm seeing over 20,000-25,000 "duplicate title tags" or "duplicate descriptions". Is this an issue? Could this issue be resolved by simply changing the canonical tag to reflect the uppercase URL's? I'm not too well versed in canonical tags and would love a little insight. Thanks!

What are Soft 404's and are they a problem
Hi, I have some old pages that were coming up in google WMT as a 404. These had links into them so i thought i'd do a 301 back to either the home page or to a relevant category or page. However these are now listed in WMT as soft 404's. I'm not sure what this means and whether google is saying it doesn't like this? Any advice welcomed.

Do search engines crawl links on 404 pages?
I'm currently in the process of redesigning my site's 404 page. I know there's all sorts of best practices from UX standpoint but what about search engines? Since these pages are roadblocks in the crawl process, I was wondering if there's a way to help the search engine continue its crawl. Does putting links to "recent posts" or something along those lines allow the bot to continue on its way or does the crawl stop at that point because the 404 HTTP status code is thrown in the header response?

Outbound link to PDF vs outbound link to page
If you're trying to create a site which is an information hub, obviously linking out to authoritative sites is a good idea. However, does linking to a PDF have the same effect? e.g Linking to Google's SEO starter guide PDF, as opposed to linking to a google article on SEO. Thanks!

Increasing Internal Links But Avoiding a Link Farm
I'm looking to create a page about Widgets and all of the more specific names for Widgets we sell: ABC Brand Widgets, XYZ Brand Widgets, Big Widgets, Small Widgets, Green Widgets, Blue Widgets, etc. I'd like my Widget page to give a brief explanation about each kind of Widget with a link deeper into my site that gives more detail and allows you to purchase. The problem is I have a lot of Widgets and this could get messy: ABC Green Widgets, Small XYZ Widgets, many combinations. I can see my Widget page teetering on being a link farm if I start throwing in all of these combos. So where should I stop? How much do I do? I've read more than 100 links on a page being considered a link farm, is that a hardline number or a general guideline?
