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!

Click To Reveal vs Rollover Navigation Better For Organic?
Hi, Any thoughts, data or insights as which is better in a top navigation... click to reveal the nav links or rollover to reveal the nav links? Regular content in an accordion (click to reveal) is evidently not best practice. Does that apply to navigation as well? Thanks! Best... Mike

P.O Box VS. Actual Address
We have a website (http://www.delivertech.ca) that uses a P.O Box number versus an actual address as their "location". Does this affect SEO? Is it better to use an actual address? Thanks.

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?

Not found errors (404) due to being hacked
Hi Moz Guru's Our website was hacked a few months ago, since then we have taken various measures, last one being redesigning the website all together and removing it from a WordPress platform. So far all is going well, except that the 404 not found errors keeps coming up in Google Webmaster tools. The URLs are spam pages that were created by the virus. And these spam pages have been indexed by Google, and now we are struggling to get rid of them. Is there any way we can deal with these 404 spam pages links? Is marking all of them as fixed in the webmaster tools - search console- crawl errors helpful in any way? Can this have a negative impact on the SEO ? Looking forward to your answers. Many thanks.

Do internal links from non-indexed pages matter?
Hi everybody! Here's my question. After a site migration, a client has seen a big drop in rankings. We're trying to narrow down the issue. It seems that they have lost around 15,000 links following the switch, but these came from pages that were blocked in the robots.txt file. I was wondering if there was any research that has been done on the impact of internal links from no-indexed pages. Would be great to hear your thoughts! Sam

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.

Wordtracker vs Google Keyword Tool
When I find keyword opportunities in Wordtracker, I'll sometimes run them through Adwords Keyword tool only to find that Google says these keywords have 0 search volume. Would you use these keywords even though Google says users aren't searching for them?
