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!

How do internal search results get indexed by Google?
Hi all, Most of the URLs that are created by using the internal search function of a website/web shop shouldn't be indexed since they create duplicate content or waste crawl budget. The standard way to go is to 'noindex, follow' these pages or sometimes to use robots.txt to disallow crawling of these pages. The first question I have is how these pages actually would get indexed in the first place if you wouldn't use one of the options above. Crawlers follow links to index a website's pages. If a random visitor comes to your site and uses the search function, this creates a URL. There are no links leading to this URL, it is not in a sitemap, it can't be found through navigating on the website,... so how can search engines index these URLs that were generated by using an internal search function? Second question: let's say somebody embeds a link on his website pointing to a URL from your website that was created by an internal search. Now let's assume you used robots.txt to make sure these URLs weren't indexed. This means Google won't even crawl those pages. Is it possible then that the link that was used on another website will show an empty page after a while, since Google doesn't even crawl this page? Thanks for your thoughts guys.

Rel=canonical and internal links
Hi Mozzers, I was musing about rel=canonical this morning and it occurred to me that I didnt have a good answer to the following question: How does applying a rel=canonical on page A referencing page B as the canonical version affect the treatment of the links on page A? I am thinking of whether those links would get counted twice, or in the case of ver-near-duplicates which may have an extra sentence which includes an extra link, whther that extra link would count towards the internal link graph or not. I suspect that google would basically ignore all the content on page A and only look to page B taking into account only page Bs links. Any thoughts? Thanks!

Images Returning 404 Error Codes. 301 Redirects?
We're working with a site that has gone through a lot of changes over the years - ownership, complete site redesigns, different platforms, etc. - and we are finding that there are both a lot of pages and individual images that are returning 404 error codes in the Moz crawls. We're doing 301 redirects for the pages, but what would the best course of action be for the images? The images obviously don't exist on the site anymore and are therefore returning the 404 error codes. Should we do a 301 redirect to another similar image that is on the site now or redirect the images to an actual page? Or is there another solution that I'm not considering (besides doing nothing)? We'll go through the site to make sure that there aren't any pages within the site that are still linking to those images, which is probably where the 404 errors are coming from. Based on feedback below it sounds like once we do that, leaving them alone is a good option.

Multiple Internal links to same destinations
My company is redoing our homepage and there will be 4 links to our main play pages (5 games). 2 in the menu and 2 within the content. I was thinking I should no follow one of the links on the homepage + 1 in the menu so that we don't have link dilution from having multiple internal links to the same destination within 1 page. Does this make sense? Any downside of this or suggestions of a solution that may be more effective? Thanks!

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:

Location.href vs href?
I just got off a Google Hangout with John Mueller and was left a little confused about his response to my question. If I have an internal link in a div like widgetwill it have the same SEO impact as widget John said that as you are unable to attribute a nofollow in an onclick event it would be treated as a naked link and would not pass pagerank but still be crawled. Can anyone confirm that I understood it correctly? If so should all my links that have such an onclickevent also have an html ahref in the too? Such as widget Many times it is more useful for the customer to click on any area of a large div and not just the link to get to the destination intended? Clarification on this subject would be very useful, there is nothing easily found online to confirm this. Thanks

Duplicate internal links on page, any benefit to nofollow
Link spam is naturally a hot topic amongst SEO's, particularly post Penguin. While digging around forums etc, I watched a video blog from Matt Cutts posted a while ago that suggests that Google only pays attention to the first instance of a link on the page As most websites will have multiple instances of a links (header, footer and body text), is it beneficial to nofollow the additional instances of the link? Also as the first instance of a link will in most cases be within the header nav, does that then make the content link text critical or can good on page optimisation be pulled from the title attribute? I would appreciate the experiences and thoughts Mozzers thoughts on this thanks in advance!

Site Architecture: Cross Linking vs. Siloing
I'm curious to know what other mozzers think about silo's... Can we first all agree that a flat site architecture is the best practice? Relevant pages should be grouped together. Shorter, broader and (usually) therefore higher volume keywords should be towards the top of each category. Navigation should flow from general to specific. Agreed? As Google say's on page 10 of their SEO Starter Guide, "you should think about how visitors will go from a general page (your root page) to a page containing more specific content ." OK, we all agree so far, right? Great! Enter my question: Bruce Clay (among others) seem to recommend siloing as a best practice. While Richard Baxter (and many others @ SEOmoz), seem to view silos as a problem. Me? I've practiced (relevant) internal cross linking, and have intentionally avoided siloing in almost all cases. What about you? Is there a time and place to use silos? If so, when and where? If not, how do we rectify the seemingly huge differences of opinions between expert folks such as Baxter and Clay?
