How many categories should you have within a blog / Wordpress Site for SEO?
-
Hi Guys
I am just wondering whether or not for SEO purposes it is better to have a small number of categories for your blog posts to fit into as opposed to numerous ones. The reason I ask is that I have one site which is fairly new to the search engines - 8 months old which has 7 general categories within the blog for instance "rail contractors", "railway construction" "airport construction" etc I have another site which is 10 years old which has built up 25 different types of categories for instance brand design, brand development, brand management (i guess you could put all these under 1 category "branding"? We've been writing lots of press for both sites... yet the younger site is getting more coverage on Google page 1. Would this be because the blogs / press are more concentrated under a specific category as opposed to being spread thinly throughout the site? Any help would be appreciated.

The number of categories on your blog can grow over time if you write about a diversity of topics. To justify a category you should have a few existing posts in that category or anticipate generating a few posts within a reasonable amount of time.
Extremely active blogs can support, and probably should have, a large diversity of categories simply to organize the content better and gain keyword reach in the search engines.
Another factor is the power of your site. If you have a new site without a lot of power then busting out 100 categories could be like dead weight on your entire site.
I have a blog that over the past several years has received 25 to 60 posts per week. It has over 150 categories and each post goes into at least two categories (one for geographic location and one for topic area). Most of the blog's search engine traffic flows in through category pages because they rank well for high traffic terms.
-
The number of categories you have on your WordPress blog should accurately reflect the content you write about. If you have a legitimate need for 50 categories, then by all means, 50 categories it is. If your content all falls under 5 categories, then that is all you should need.
Essentially, let your content dictate how many categories your blog has. Remember to look out for duplicate content, or pages with little to no content. It's possible that you have a single blog post that is tagged to two categories - and those categories have no other posts attributed to them. The category pages will then show short excerpts of the content (little to no content), and be essentially identical because the same post is tied to them (duplicate content).
-
Define the goal for your blog, categorize as appropriate for keywords and the content you will need to create to achieve your goal and then, create your blog posts to fit within your categories.
As far as which is getting more traffic and why, is the traffic you're looking at going to category pages or individual blog posts? More "coverage on Google page 1" doesn't mean anything if it's not earning traffic to the site. Are the blog posts bringing in search traffic? If they are and that traffic is going to the individual posts, then it may be that the posts are better optimizer or the topics you're writing about on the new blog are better chosen. If you're seeing traffic going to the category pages for category keywords on one site but not the other, maybe your keyword research for the category pages wasn't done well enough, maybe you just have to give it more time, or maybe you have to take a look at your internal and external links to see why one site is out performing the other.

You should have as many as you need. Do not create categories if there are no articles you can place within them. But do not group unrelated articles under the same category. Check into some keyword research to see if your broader categories get search volume and go from there.
For the example you gave, I would say to keep them all under a "branding" category and expand into those other keywords through articles.
If you have a more broad category it may get linked to more since it has more articles people may want. Therefore increasing its PA and ranks

Can We Publish Duplicate Content on Multi Regional Website / Blogs?
Today, I was reading Google's official article on Multi Regional website and use of duplicate content. Right now, We are working on 4 different blogs for following regions. And, We're writing unique content for each blog. But, I am thinking to use one content / subject for all 4 region blogs. USA: http://www.bannerbuzz.com/blog/ UK: http://www.bannerbuzz.co.uk/blog/ AUS: http://www.bannerbuzz.com.au/blog/ CA: http://www.bannerbuzz.ca/blog/ Let me give you very clear ideas on it. Recently, We have published one article on USA website. http://www.bannerbuzz.com/blog/choosing-the-right-banner-for-your-advertisement/ And, We want to publish this article / blog on UK, AUS & CA blog without making any changes. I have read following paragraph on Google's official guidelines and It's inspire me to make it happen. Which is best solution for it? Websites that provide content for different regions and in different languages sometimes create content that is the same or similar but available on different URLs. This is generally not a problem as long as the content is for different users in different countries. While we strongly recommend that you provide unique content for each different group of users, we understand that this may not always be possible. There is generally no need to "hide" the duplicates by disallowing crawling in a robots.txt file or by using a "noindex" robots meta tag. However, if you're providing the same content to the same users on different URLs (for instance, if both example.de/ and example.com/de/ show German language content for users in Germany), you should pick a preferred version and redirect (or use the rel=canonical link element) appropriately. In addition, you should follow the guidelines on rel-alternate-hreflang to make sure that the correct language or regional URL is served to searchers.

How long should a quality blog post be?
How long should a "quality" blog post be? General advice seems to be that a 300 word post just won't cut it, but advice on the optimum length is vague. I appreciate that all posts are different but is there a rule of thumb, is 1000 words good and 1500 too long...or should they are all aim to be 2000 words? Also with regards to pictures in blogs, can they just be taken from the web or are there sites that I should be using to source the pictures? Thanks

Should a business blog be on a separate site or on the ecommerce site itself?
Hey there. I'm a new Pro member and this will be my first question on the Q&A. Thanks in advance for your responses. I'm the owner of an ecommerce site that sells custom candles. www.prometheancandle.com in case anyone wants to take a peak. I've become somewhat of an expert on all-things-candles over the past 4 years and I am thinking about starting a candle related blog. My question is this. Should I build this blog on the ecommerce site itself, say @ www.prometheancandle.com/blog.php, or should I devote a separate site to answering candle related question, history of candles, etc? At first, I was thinking that the blog should remain on the ecommerce site so readers would have easy access to the shop to be able to purchase products. But then it occurred to me that people who may be interested in reading up on candle history, candle making, meditation & candles, etc., may not want to go to an obviously ecommerce site to do that. I know Google values informational sites more than ecommerce sites (at least I think they do), so that encourages me to lean towards the separate site. Well, I may have just answered this question myself, but I'd definitely be interested to hear feedback and opinions. Thanks so much guys and I look forward to hearing from you.

Can you have too many words on a page for SEO?
One line of thinking is that you can not have too many words on a page because the more words you have the higher the chances that a long tail phrase will attract traffic. But can you go overboard with this? Is there a limit to the number of words on a page in terms of SEO?
