How hard would it be to take a well-linked site, completely change the subject matter & still retain link authority?
-
So, this would be taking a domain with a domain authority of 50 (200 root domains, 3500 total links) and, for fictitious example, going from a subject matter like "Online Deals" to "The History Of Dentistry"... just totally unrelated new subject for the old/re-purposed domain. The old content goes away entirely.
The domain name itself is a super vague .com name and has no exact match to anything either way. I'm wondering, if the DNS changed to different servers, it went from 1000 pages to a blog, ownership/contacts stayed the same, the missing pages were 301'd to the homepage, how would that fare in Google for the new homepage focus and over what time frame? Assume the new terms are a reasonable match to the old domain authority and compete U.S.-wide... not local or international.
Bonus points for answers from folks who have actually done this.
Thanks... Darcy

Still Need to Write Title & Description Tag?
My SEO has advised me that Google has stopped using title and description tags for search results and as such, it is no longer necessary to write specific title and description tags. I see that Yoast seems to pull text to create these tags and sometimes it looks like it reflects the best elements of the content, sometimes it does not. Should I be asking our SEO team to write dedicated title and description tags or is it best practices to leave it to the Yoast plugin? My SEO is of the opinion that writing these tags is not a productive use of time as Google will serve results based on the user inquiry rather than the content on his tags. It sounds logical but it would be reassuring to receive further confirmation of this. Thoughts?"

Unpaid Followed Links & Canonical Links from Syndicated Content
I have a user of our syndicated content linking to our detailed source content. The content is being used across a set of related sites and driving good quality traffic. The issue is how they link and what it looks like. We have tens of thousands of new links showing up from more than a dozen domains, hundreds of sub-domains, but all coming from the same IP. The growth rate is exponential. The implementation was supposed to have canonical tags so Google could properly interpret the owner and not have duplicate syndicated content potentially outranking the source. The canonical are links are missing and the links to us are followed. While the links are not paid for, it looks bad to me. I have asked the vendor to no-follow the links and implement the agreed upon canonical tag. We have no warnings from Google, but I want to head that off and do the right thing. Is this the right approach? What would do and what would you you do while waiting on the site owner to make the fixes to reduce the possibility of penguin/google concerns? Blair

How to identify 404 that get links from external sites (but not search engines)?
one of our site had a poor site architecture causing now about 10.000s of 404 being currently reported in google webmaster tools. Any idea about easily detecting among these thousands of 404, which ones are coming from links from external websites (so filtering out 404 caused by links from our own domain and 404 from search engines)? crawl bandwidth seems to be an issue on this domain. Anything that can be done to accelerate google removing these 404 pages from their index? Due to number of 404 manual submission in google wbt one by one is not an option.

Or do you believe that google automatically will stop crawling these 404 pages within a month or so and no action needs to be taken? thanks0 -
How do I best deal with pages returning 404 errors as they contain links from other sites?
I have over 750 URL's returning 404 errors. The majority of these pages have back links from sites, however the credibility of these pages from what I can see is somewhat dubious, mainly forums and sites with low DA & PA. It has been suggested placing 301 redirects from these pages, a nice easy solution, however I am concerned that we could do more harm than good to our sites credibility and link building strategy going into 2013. I don't want to redirect these pages if its going to cause a panda/penguin problem. Could I request manual removal or something of this nature? Thoughts appreciated.

On-site links
Hi everybody, There's a lot of information about getting sitewide backlinks, but so few about on-site optimization. Is there a maximum of links to put on a page ? Is there a maximum of link that a page should receive ? etc ... ? So, what is the optimal strategy ? And I'm only concerned about on-page and on-site link, not backlinks commming from other sites. Thanks
