Thoughts on using a CDN?
-
I'm trying to decide if I should use a CDN to speed up my site. I've never used one before, but I do know that there are a lot of images on my site and I think that could help a great deal.
Are they hard to set up? Are there any down sides? And are the pricey?
Also I'm not sure even sure if it would make a difference for me, but I want to work on getting my site faster.
Thanks.

This in no way endorses or not any one cdn but I will share what has happened to me over the last few months.
My hosting company gave me the option of using a well known cdn free with my hosting package. Now as my site is hosted in the US and most of my visitors are from the UK I thought that would be a good idea. So end of August I enable the cdn for my site.
From mid sept the time it took googlebot to crawl an individual page on my site went up from average 150ms to over 4000ms. The number of pages crawled per day remain the same.
However looking at the index status the number of pages not selected has increase by some 30% when I have not been adding any content to the site.
At end of Sept for most of my page my ranking fell by about 950 places. There were no messages in WMT and a reconderation request came back saying no manual penalty.
At the end of Oct I disable the CDN and immeadiately the time googlebot took on each page fell back down to the 150ms mark. Rankings are yet to improve so I am not saying this was the only cause of the drop in rankings.
I am now getting a lot of 404 not found appearing in my wmt crawl errors for pages that have never exisited on my site but have no mention of the cdn in them either.
I am talking with the cdn provider at the moment so have not named them here.

Hi, I work at Incapsula and I've just recently wrote a 2 part Blog Post that look and CDN from a SEO point-of-view. The first post deals with SEO & CDN Myths and the second one covered CDN related SEO Benefits. I hope you`ll find this helpful.
Admittedly, I do work for a CDN provider, but I also have 7+ year of prior SEO experience (both as Freelancer, Senior Adviser, CTO and SEO/SEM Department Manager) and so, in my post, I insisted on conduction balanced discussion, using only Google official statements to prove my point.
Hope this helps.

I've just signed upto http://www.incapsula.com/
It was the most pain free setup compared to another I have tried.
They have various versions available. Also stopped all my spam registrations!

i used amazon cdn and was not impressed with the service but i have been told there are some good ones out there, it is just finding the good ones.

No problem. Be sure to let me know if you end up trying one.

I was suspicious that it might cause a rankings problem. Thanks for sharing what you read.
I would like to read an evaluation of the service done by a top SEO with deep technical knowledge. What happens when you start bouncing every visitor from a high traffic country? Will I lose image search traffic when my files are modified out to their service? What else do they add to my site or change? Sucking any linkjuice?

Yah, I read up on CloudFrare, but it looks like a lot of people don't like them / suggest them. Some people even saying they lost a lot of rankings after using them.

I was looking at CloudFlare.
I wanted to speed up the site, limit access to certain countries, and get some of their security enhancements.
The cost can be free if you use minimal services or $20/month if you want a lot more.
I didn't do it because I had some concerns about their use of my data, how they might rewrite URLs on my site with affiliate codes, how blocking certain countries might impact search rankings, and more.
I really like their services but have research to do before I decide that it is a good thing for me.

Moving servers which means moving ip address but using the same URL. Would it harm the website's SEO?
Hello everyone, The server (in-house) which we use to host our website is a bit old. We are using CDN77 for our static content. What if I move all our website to the CDN service? meaning I use their storage capability and just have our url point to the IP address they provide. Would that hurt our rankings?

What do you use for test rendering your dev site?
I'm redesigning our company ecommerce site and need to test render an infinite scroller to ensure that it is as SEO friendly as possible. My problem is that I cannot view it in Webmaster Tools since I am blocking the site from crawlers using robots.txt. I know I could simply unblock Google temporarily but I really would rather not make my dev site available to search engine crawlers.

Thoughts about Comment Luv?
What do you think about the Comment Luv pro plugin for your blog? My goal is this would help me get traffic and comments on my posts..... Make it easy to promote my own content.... the unlimited version is $97, I thought about purchasing this for my site and all my clients but wasn't sure if this was just one more tool that I spend money on and 6 months later I don't use it because I have learned about a better option (that is usually free). I am sure many of you can relate to doing that 🙂 Thank you very much for any suggestions!!! Have a superb week everybody! Matthew

Nav / Sitemap Question. Using a "services" page vs just linking directly to individual service page?
Okay, so our company offers video production, web design, and web marketing services. While we do offer these services individually, our goal is to get our clients to integrate these services together. Our nav is currently like so : home - about - video - web design - web marketing - blog - contact Now I've seen businesses and agencies also use a nav with a "services" button instead of listing out their service offerings (if they have more than 1, like us). The services button usually links to a category page or has a drop down with links to the company's individual services. I'm wondering if there is any benefit to having a main services page like this and linking to the individual pages off of it (video ,web design, marketing, etc). Or if we should just keep it the way we have it now (since we've already got some page authority on the individual service pages). I know this may not be the most important aspect of our site and we may be over-thinking it but any thoughts/ideas would be greatly appreciated, thanks!

Thoughts on my site structure? (And a quick thank you!)
I've learned a lot through this site (and the community built around it) about everything SEO related. It's been extremely helpful in helping us help others to learn that all people (even those with a "disability") deserve respect and integrity. (Wow, that's a lot of helps!) So I wanted to give a quick thanks to everyone on this site who has helped, supported, and encouraged us. We really appreciate it. One thing I've been trying to do on my site is look at my categories and over all site structure. I've pruned a lot of things from the menu bar; pruned away and tightened up the categories, and even rearranged the navigation of the site. As you can see, I have several drop down categories up top. I wanted to see if I could get some feedback on how what I'm doing looks thus far, specifically as it relates to my categories / menus / navigation. Although any feedback you'd like to provide would be more than appreciated. One thing I'm curious about (and not sure how to tackle it) is regarding the top most item in the main menus. For instance you'll see I have a top level category called "Down Syndrome Resources" which takes them to all of the posts in that category. Under that, there is a drop down menus that gives them other categories, and even some pages that fall under the topic of Down syndrome resources. I'm not sure if people would know the top most item is a link, or just look at the ones below it. (If that makes sense.) (On a side note I have therapy as a category as well as parenting, the truth is those could all be sub-categories I guess since everything on my site pretty much could fall under "down syndrome resources." Maybe this is a huge FAIL I made when setting up my categories.) I'm also not sure if I should use some sub-categories as well. For instance I have a main category for Therapy. Under that I have posts about speech therapy, physical therapy, and occupational therapy. Right now they are all grouped into therapy. Do you think I should use sub-categories on those 3 terms, leave as is, or perhaps another option? Another question I have is regarding landing pages. It seems like I need to have a landing page for my top "key words." For example therapy. Now if you visit my /therapy you get the category index page, not a "landing page." Same would go for the sub-categories if I were to create them. So I'm not sure if I should make a new post or page naming it something else (maybe "Down syndrome therapy" another named "Down-syndrome-physical-therapy" etc) or something else. (Although therapy isn't really the keyword I want to rank for, I'm thinking more along the lines of children therapy, pediatric therapy, therapy for children with Down syndrome, etc. So maybe I need to rename my categories? I was going for shorter names, so I very well may have done this incorrectly.) All of these questions are things I'm not to sure about, so I'd appreciate any feedback or advice you can give me. And since I'm learning, I could be doing things wrong that I don't even know to ask. So feel free to tell me what you see that's wrong, you won't hurt my feelings. I promise. 🙂 Thanks in advance.

Is there any difference in using an underscore vs. a dash in the directory portion of the url?
A friend who is a software developer asked this question regarding the directory portion of the url: Is it better to use dashes or underscores? I know in the domain name Matt Cutts recommends dashes, but what about the directory extension?
