Welcome to the Q&A Forum

We made a change to our site where we all of a sudden we are creating a large number of 404 pages.  Is this effecting the crawl/indexing rate? Currently we've submitted 3.4 million pages, have over 834K indexed but have over and 330K pages not found.  Since the large increase in 404s we've noticed a decrease in pages crawled per day.  I found this Q & A in Webmasters (http://googlewebmastercentral.blogspot.com/2011/05/do-404s-hurt-my-site.html) but it seems like the 404s should not have an effect.  Is this article out of date? What do you think fellow Moz-ers? Is this a problem?

I am working with a site that recently deployed Angular.js on the site.  From an SEO standpoint its a little more tricky than we thought.  We have deployed a couple updates to render pages for the bots but we not seeing changes in Moz weekly reports. When it comes to Angular.js, will the Moz bots read/access the site the same as the other major engines?  I'm trying to figure out if our deployments are working or if there's something off in the Moz reports. Thanks.

I have a site where I have 500+ Page listing pages and I would like to rel=canonical them to the master page. Example: http://www.example.com//articles?p=18 OR http://www.example.com/articles?p=65 I plan on adding this to the section from of the page template so it goes to all pages - When I do this, I will also add the canonical to the page I am directing the canonical.  Is this a bad thing?  Or allowed?

Meaning, is there a way I could look at the Page Authority for 50 pages all in one place?  Or do I need to use the MozBar and go page by page? Just looking to save some time.  Thanks.

I have a site where dozens of page listings are showing in my report with a parameter showing the page number for the listings.  Is the best solution to canonical these page listings back a core page (all-products)?  Or, do I change my site configuration in Webmasters to ignore "page" parameters?  What's the solution? Example URL 1- http://mydomain.com/products/all-products?page=84 Example URL 2- http://mydomain.com/products/all-products?page=85 Example URL 3- http://mydomain.com/products/all-products?page=86 Thanks in advance for your direction.

I have found conflicting reports online whether or not dashes in domain names hurt/help ranking.  Example yourbrandonline.com vs your-brand-online.com? I found Rand's write up on how to select a domain and he suggests staying away from hyphens but mainly because its hard to remember or people my enter it in wrong.  Here's his comment. "Reject Hyphens and Numbers
Both hyphens and numbers make it hard to give your domain name verbally and falls down on being easy to remember or type. I'd suggest not using spelled-out or roman numerals in domains, as both can be confusing and mistaken for the other." Aside from people possibly struggling to get there directly because of the domain name, are they OK to use?  Or, are domains with hyphens considered spammy? Thanks in advance.
