Rel Noindex Nofollow tag vs meta noindex nofollow
-
Hi Mozzers
I have a bit of thing I was pondering about this morning and would love to hear your opinion on it.
So we had a bit of an issue on our client's website in the beginning of the year. I tried to find a way around it by using wild cards in my robots.txt but because different search engines treat wild cards differently it dint work out so well and only some search engines understood what I was trying to do. so here goes,
I had a parameter on a big amount of URLs on the website with ?filter being pushed from the database we make use of filters on the site to filter out content for users to find what they are looking for much easier, concluding to database driven ?filter URLs (those ugly &^% URLs we all hate so much*.
So what we looking to do is implementing nofollow noindex on all the internal links pointing to it the ?filter parameter URLs, however my SEO sense is telling me that the noindex nofollow should rather be on the individual ?filter parameter URL's metadata robots instead of all the internal links pointing the parameter URLs. Am I right in thinking this way? (reason why we want to put it on the internal links atm is because the of the development company states that they don't have control over the metadata of these database driven parameter URLs)
If I am not mistaken noindex nofollow on the internal links could be seen as page rank sculpting where as onpage meta robots noindex nofolow is more of a comand like your robots.txt
Anyone tested this before or have some more knowledge on the small detail of noindex nofollow?
PS: canonical tags is also not doable at this point because we still in the process of cleaning out all the parameter URLs so +- 70% of the URLs doesn't have an SEO friendly URL yet to be canonicalized to.
Would love to hear your thoughts on this.
Thanks,
Chris Captivate.

I'm not a fan of doubling up, but only because it makes the results really hard to measure. If you implement both, you won't know which one worked, ultimately. I'm not sure it's actually harmful - it just can be hard to track.
If you're just trying to prevent future problems (and don't have any immediate issues), I'd probably pick one and give it a few weeks.

Hi Dr Pete
Thank you so much for your input, I really appreciate it. Always fun learning something new
I also don't prefer the engine-specific approach. However, could it hurt implementing both solutions?
Regards,
Chris Captivate.

A couple of options here. First off, though, there's really no rel="noindex" at the link level. You can "nofollow" a link, and that generally disrupts indexing, but it's not guaranteed. You're right that it can look like PR sculpting, although that's not a huge issue if your usage makes sense. In other words, if you're using rel=nofollow to keep the crawlers away from content with low search value, I generally think that's ok.
You could META noindex, nofollow the target pages, although then Google has to crawl those. The advantage is that I find the META Robots approach to be a bit more powerful.
The other option is to use parameter handling in Google Webmaster Tools (Bing has a similar function) to tell Google to ignore the "?filter" parameter. The purist in me doesn't love the engine-specific approach, but it's easier, you don't need to change the site itself, and it typically works fairly well.

Is it Okay to Nofollow all External Links
So, we all "nofollow" most of the external links or all external links to hold back the page rank. Is it correct? As per Google, only non-trusty and paid links must be nofollow. Is it all same about external links and nofollow now?

Title Tag : use comma, pipe or colon (:)
Hi, If Title has two and three keywords then which one is better option to separate them either with comma or pipe or colon. Example : Arvixe Review, Coupons (Jun 2015) and Uptime Report (I used (,) as a separator) Arvixe Review is primary keywords and Coupons and Uptime are secondary keywords. Aim is rank on keywords like Arvixe Review, Arvixe Coupons and Arvixe Uptime.

Also, including current month and year with Title tag and it will change every month. Its means every month our title is changed.
Is this effect in SEO? Suggest best possible title for keywords like Arvixe Review, Coupons (Jun 2015) and Uptime Report. Rajiv0 -
Real Vs. Virtual Directory Question
Hi everyone. Thanks in advance for the assistance. We are reformatting the URL structure of our very content rich website (thousands of pages) into a cleaner stovepipe model. So our pages will have a URL structure something like http://oursite.com/topic-name/category-name/subcategory-name/title.html etc. My question is… is there any additional benefit to having the path /topic-name/category-name/subcategory-name/title.html literally exist on our server as a real directory? Our plan was to just use HTACCESS to point that URL to a single script that parses the URL structure and makes the page appropriately. Do search engine spiders know the difference between these two models and prefer one over the other? From our standpoint, managing a single HTACCESS file and a handful of page building scripts would be infinitely easier than a huge, complicated directory structure of real files. And while this makes sense to us, the HTACCESS model wouldn't be considered some kind of black hat scheme, would it? Thank you again for the help and looking forward to your thoughts!

Should I delete Meta Keywords from a website?
Hi Guys, I've been reading various posts on the Q&A section here at Moz about Meta keywords. I understand that meta keywords are not relevant with Google and that Bing signals this as spam. I'm optimising existing websites which already have meta keywords in the html coding. My question is: If I delete ALL meta keyword coding will this have any negative impact whatsoever? Thanks Mozers Jason 🙂

Tags on WordPress Sites, Good or bad?
My main concern is about the entire tags strategy. The whole concept has really been first seen by myself on WordPress which seems to be bringing positive results to these sites and now there are even plugins that auto generate tags. Can someone detail more about the pros and cons of tags? I was under the impression that google does not want 1000's of pages auto generated just because of a simple tag keyword, and then show relevant content to that specific tag. Usually these are just like search results pages... how are tag pages beneficial? Is there something going on behind the scenes with wordpress tags that actually bring benefits to these wp blogs? Setting a custom coded tag feature on a custom site just seems to create numerous spammy pages. I understand these pages may be good from a user perspective, but what about from an SEO perspective and getting indexed and driving traffic... Indexed and driving traffic is my main concern here, so as a recap I'd like to understand the pros and cons about tags on wp vs custom coded sites, and the correct way to set these up for SEO purposes.

Subdomains vs. Subfolders Wordpress Multisite
I am in the process redesigning my organization's website using wordpress multisite. I am currently planning on creating subdomains for each of the locations, as I thought that having a keyword saturated domain name would provide the best rankings. So the Omaha office would look like this: omaha.example.com Would it be better to go with example.com/omaha? Things to consider: Google adwords is currently a huge source of our traffic. Despite having very good organic rankings, we receive most of our traffic from pay-per-click sources. The "display URL" has dramatic effect on our CTR, so I want to avoid subfolders if possible. (example OmahaEmergencyDental.com receives far more click thru's than EmergencyDental.com) Each location currently has it's own domain and website (omahaemergencydental.com) these sites/pages have been in place for several years Thanks in advance!
