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

Internal blog with history and some SEO value versus new external blogs with specialized content?
We operate a blog inside a folder on our site and considering the launch of 4 highly focused blogs with specialized content which are now categories on the internal blog. Wondering if there is more value in using the external new blogs or just keep growing the internal blog content. Does fact that the internal blog is buried amongst millions of pages have any impact if we want the content indexed and value given to the links from the blog content to our main site pages.

Pages and categories with the same name?
I manage a wordpress based site that is needing to under go a site architecture overhaul. the site is christ.org and one of the problems is it has 89 pages but really only 4 are navigatable (not a word apparently). The site also has over 400 posts so categories and parent pages are both definitely needed. One option is I convert a lot of the pages into posts, but would that happen to break any links pointing to those pages turned posts? Or another option is to keep the pages and posts and create a bunch of subpages, then I would most likely end up with similarly named categories and top level pages. I would guess the name of the category needs to be unique from page titles right? And not just unique but very much differentiated than any page title (not posts but page titles). Maybe what I need to do is convert the pages that are not really unique into posts and put them in the category it fits with. And then keep those that are unique as top level pages. The architecture needs some serious work I think 🙂 Any help would be greatly appreciated.

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.

Onsite Blogging Vs Guest Blogging
Hey all! I have a limited amount of time allocated to writing instructional blog posts for my company. When I complete an article I can do whatever I want with it: pitch it as a guest post on an industry blog, or post it on my company's onsite blog. I know there's not a magical solution regarding the percentage of time one should devote to guest blogging v. focusing on the company blog, but I figured I'd throw the conundrum out to the Mozzers anyway. In your opinion, how many of your writing resources should be devoted to guest posts, and how many should be devoted to maintaining the onsite blog? What if our onsite blog isn't currently receiving a lot of traffic? Thanks! Meg

How many pages is too many to add to a site at one time?
I have quite a bit of excellent content articles at my disposal and we would like to increase the number of pages on our site. I could, theoretically add 100's of pages at a time. Does anyone have a good sense of how much content added to a sight in mass looks bad to Google? My plan is to add approximately 50 pages a week to our site, which already has 4000 pages of content. This is relevant content, since we are a custom writing service and all topics are covered. Our content is what gives us great organic hits and orders. However, I would like to add more than 50 a week...how many is too many? Thanks and I appreciate thoughts and feedback! Karen
