Image search and CDNs
-
Hi,
Our site has a very high domain strength. Although our site ranks well for general search phrases, we rank poorly for image search (even though our site has very high quality images). Our images are hosted on a separate CDN with a different domain. Although there are a number of benefits to doing this, since they are on a different domain, are we not able to capitalize on our my site's domain strength? Is there any way to associate our CDN to our main site via Google webmaster tools? Has anyone researched the search ranking impacts due to storing your images on a CDN, given that your domain strength is very high?
Curious on people's thoughts?

Hi NicB1,
We use Amazon CloudFront here at SEOmoz and it allows us to setup a CNAME for our CDN. So if you look at our images you will see we use a few different ones, such as cdn.seomoz.org, profile1.seomoz.org and profile2.seomoz.org. While I haven't done any studies on this, I can tell you that we have not seen a major change in image traffic in making the CDN switch a few months ago.
I'd check with your CDN people and see if you can setup a CNAME and place it on a subdomain.

I'll leave it to others who might have done serious testing on this to discuss findings. I will say this though - if the CDN is not a domain you own, or can readily show through other optimization efforts that you own it, it's at least partly a matter of "how do we know this site owns these images?". Purely from SEO best practices thinking, when a site hosts their images, there's a much lower threshold of being able to have them recognized for consideration, let alone associated with image names, alt attributes, and page topical focus.

Why has my search traffic suddenly tanked?
On 6 June, Google search traffic to my Wordpress travel blog http://www.travelnasia.com tanked completely. There are no warnings or indicators in Webmaster Tools that suggest why this happened. Traffic from search has remained at zero since 6 June and shows no sign of recovering. Two things happened on or around 6 June. (1) I dropped my premium theme which was proving to be not mobile friendly and replaced it with the ColorMag theme which is responsive. (2) I relocated off my previous hosting service which was showing long server lag times to a faster host. Both of these should have improved my search performance, not tanked it. There were some problems with the relocation to the new web host which resulted in a lot of "out of memory" errors on the website for 3-4 days. The allowed memory was simply not enough for the complexity of the site and the volume of traffic. After a few days of trying to resolve these problems, I moved the site to another web host which allows more PHP memory and the site now appears reliably accessible for both desktop and mobile. But my search traffic has not recovered. I am wondering if in all of this I've done something that Google considers to be a cardinal sin and I can't see it. The clues I'm seeing include: Moz Pro was unable to crawl my site last Friday. It seems like every URL it tried to crawl was of the form http://www.travelnasia.com/wp-login.php?action=jetpack-sso&redirect_to=http://www.travelnasia.com/blog/bangkok-skytrain-bts-mrt-lines which resulted in a 500 status error. I don't know why this happened but I have disabled the Jetpack login function completely, just in case it's the problem. GWT tells me that some of my resource files are not accessible by GoogleBot due to my robots.txt file denying access to /wp-content/plugins/. I have removed this restriction after reading the latest advice from Yoast but I still can't get GWT to fetch and render my posts without some resource errors. On 6 June I see in Structured Data of GWT that "items" went from 319 to 1478 and "items with errors" went from 5 to 214. There seems to be a problem with both hatom and hcard microformats but when I look at the source code they seem to be OK. What I can see in GWT is that each hcard has a node called "n [n]" which is empty and Google is generating a warning about this. I see that this is because the author vcard URL class now says "url fn n" but I don't see why it says this or how to fix it. I also don't see that this would cause my search traffic to tank completely. I wonder if anyone can see something I'm missing on the site. Why would Google completely deny search traffic to my site all of a sudden without notifying any kind of penalty? Note that I have NOT changed the content of the site in any significant way. And even if I did, it's unlikely to result in a complete denial of traffic without some kind of warning.

Inurl: search shows results without keyword in URL
Hi there, While doing some research on the indexation status of a client I ran into something unexpected. I have my hypothesis on what might be happing, but would like a second opinion on this. The query 'site:example.org inurl:index.php' returns about 18.000 results. However, when I hover my mouse of these results, no index.php shows up in the URL. So, Google seems to think these (then duplicate content) URLs still exist, but a 301 has changed the actual goal URL? A similar things happens for inurl:page. In fact, all the 'index.php' and 'page' parameters were removed over a year back, so there in fact shouldn't be any of those left in the index by now. The dates next to the search results are 2005, 2008, etc. (i.e. far before 2013). These dates accurately reflect the times these forums topic were created. Long story short: are these ~30.000 'phantom URLs' in the index out of total of ~100.000 indexed pages hurting the search rankings in some way? What do you suggest to get them out? Submitting a 100% coverage sitemap (just a few days back) doesn't seem to have any effect on these phantom results (yet).

Why is my site jumping around in google search ?
Hi I've been trying to get my page up in google results and I was wondering why the constant fluctuation. For example, on one day the pages is nr. 26, the next day it's nr. 65 then jumps back on say 30 and then in a few more days it's going back to 50. What's the logic behind that ? Thanks Cezar

What happens when you put an image in an H1 tag?
I am currently updating some H1 tags for my site but the tags are generated automatically by the text that is entered into a field on our content manager software. However because we need an image in this area as well, the entire field including the code for the image is surrounded by an H1 tag. Is this bad for SEO?

How to stop Search Bot from crawling through a submit button
On our website http://www.thefutureminders.com/, we have three form fields that have three pull downs for Month, Day, and year. This is creating duplicate pages while indexing. How do we tell the search Bot to index the page but not crawl through the submit button? Thanks Naren
