We're trying to standardize the use of tags on our site amongst writers/editors, and I'm trying to come up a list of tags they can choose from to tag posts with - and telling them to use no more than 10 (absolute maximum) per post. We are also in the process of migrating to a new CMS, and have 8 defined categories that will all have their own landing page within our "News" section. TLDR: Do blog tags have any impact on SEO anymore? Are they solely meant to help users find articles related on popular topics, or does creating a tag for a popular topic help to improve organic visibility? Full Question: With the tag standardization, I want to make sure we're creating the most useful and effective tags; and the UX/SEO sides of my brain are conflicted. To my understanding, creating a tag about a high volume topic in an industry helps establish the website's relevance to Google/other search engines about that topic and improves overall relevance; but the tag feed page (ex: http://freshome.com/tag/home-protection/) isn't really meant for organic search visibility. So my other question is, is it worth it to noindex the tag pages in the robots.txt? Will that affect any benefit to increased relevance for Google (if there is any)? I'm interested to hear others' thoughts and suggestions. Thanks in advance!

Hello, I have a main domain example.com where I have my main content and then I created 3 subdomains one.example.com, two.example.com and three.example.com I think the low ranking of my subdomains is affecting the ranking of my main domain, the one I care the most. So, I decided to get rid of the subdomains. The thing is that only for one.example.com I could transfer the content to my main domain and create 301 redirects. For the other two subdomains I cannot integrate the content in my main domain as it doesn't make sense. Whats the cleanest way to make them dissapear? (just put a redirect to my main domain even if the content is not the same) or just change the robots to "noindex" and put a 404 page in the index of each subdomain. I want to use the way that will harm the least the performance with Google. Regards!

I just signed up for Moz recently, and have noticed that in my crawl errors, I have hundreds of issues with my title tag being too long. My business is selling prints for landscape/travel/nature photography, and I've built these pages dynamically to where the title tag for pages selling individual photos has the title of the photo for sale followed by a hyphen and then the brand name. The same goes for gallery pages "Gallery Name | Brand Name". Would it be worth it to shorten the title tags by removing the brand name from these pages? Or will that actually harm more than help? Thanks in advance!

I've noticed that when I change my blog's template the traffic goes down dramatically, about of 40% decrease. I know that new themes can have some problems but I have tried this with 2 different themes. First try was with genesis framework(Paid one) and just in one day traffic went down and when I reverted the old theme, the traffic became normal. Should I wait for 1 week to see what happens? What could be the potential reason of this?

I recently removed about 600 'thin' pages from my site which are now showing as 404 errors in WMT as expected. As I understand it I should just let these pages 404 and eventually they'll be dropped from the index. There are no inbound links pointing at them so I don't need to 301 them. They keep appearing in WMT as 404's though so should I just 'mark as fixed' until they stop appearing? Is there any other action I need to take?

My categories are indexed and I want to change the category page title. At present it just defaults to the category name but I want to set a different page title. For example I want the category to be 'Motor Cars' but I want the category page title to be 'Buy Motor Cars - New And Used'. How can I do this?

I just recently learned that changing your page title earns you a google penalty.  Unfortunately i learned this after playing around with my page titles a bit to get the most optimal page titles.  Does anybody know how long this google penalty lasts? is it forever? or just temporary?

What is the best SEO page/link structure for a blog with, say 100 posts that grows at a rate of 4 per month? Each post is 500+ words with charts/graphics; they're not simple one paragraph postings. Rather than use a CMS I have a hand crafted HTML/CSS blog (for tighter integration with the parent site, some dynamic data effects, and in general to have total control). I have a sidebar with headlines from all prior posts, and my blog home page is a 1 line summary of each article. I feel that after 100 articles the sidebar and home page have too many links on them. What is the optimal way to split them up? They are all covering the same niche topic that my site is about. I thought of making the side bar and home page only have the most recent 25 postings, and then create an archive directory for older posts. But categorizing by time doesn't really help someone looking for a specific topic. I could tag each entry with 2-3 keywords and then make the sidebar a sorted list of tags. Clicking on a tag would then show an intermediate index of all articles that have that tag, and then you could click on an article title to read the whole article. Or is there some other strategy that is optimal for SEO and the indexing robots? Is it bad to have a blog that is too heirarchical (where articles are 3 levels down from the root domain) or too flat (if there are 100s of entries)? Thanks for any thoughts or pointers.
