SEO Impact of External links in JS tag
-
We have our JS tag and iframe tag being used over by 100 leading websites. What would be the SEO impact if we added a follow link in the iframe. Would it have any negative impact ?

No, I know that you're not trying to do anything malicious however unfortunately
it will not pass juice unless you rig it to do something completely black hat
Here are examples of what 00 tags are being considered by antivirus and malware services you really should be able to pass this with a regular redirect, not anything that is hidden in a clear photo

I hope this helps,

I have my JS tag ( which loads a 0X0 iframe also) is over 100 sites. If I add a follow link in the iframe, will it help in building my domain authority.

I don't disagree with you about Dom or Google successfully crawling Java/Ajax the issue is the I-frame's I do not believe that the current time they are an ideal situation. It may be possible I think the future has Java written all over it but if I were going to bed on it I would not use I-frames.
Great article I wish it covered the I-frame itself

Google can crawl pretty much but it wants but does it advise you to here is the answer

Alright. Any supporting article that talks about this ?

I wish I had the ability to be in for a computer and give you a more complete answer but using I-frames and hoping Google will index them is a recipe for disaster.

Lightboxes and SEO
Do lightboxes (AKA popup boxes when you click "learn more" type CTAs) have any negative effect on SEO? We are looking at revamping our sites to have more of a tiled approach, and a lightbox with summary content popping out with additional CTAs, directing to pages with more information or free trial pages. Is there any downside to this approach from an organic perspective? is there anything specific to keep in mind when creating these if not?

If I nofollow outbound external links to minimize link juice loss > is it a good/bad thing?
OK, imagine you have a blog, and you want to make each blog post authoritative so you link out to authority relevant websites for reference. In this case it is two external links per blog post, one to an authority website for reference and one to flickr for photo credit. And one internal link to another part of the website like the buy-now page or a related internal blog post. Now tell me if this is a good or bad idea. What if you nofollow the external links and leave the internal link untouched so all internal links are dofollow. The thinking is this minimizes loss of link juice from external links and keeps it flowing through internal links to pages within the website. Would it be a good idea to lay off the nofollow tag and leave all as do follow? or would this be a good way to link out to authority sites but keep the link juice internal? Your thoughts are welcome. Thanks.

Null Alt Image Tags vs Missing Alt Image Tags
Hi, Would it be better for organic search to have a null alt image tag programatically added to thousands of images without alt image tags or just leave them as is. The option of adding tailored alt image tags to thousands of images is not possible. Is having sitewide alt image tags really important to organic search overall or what? Right now, probably 10% of the sites images have alt img tags. A huge number of those images are pages that aren Thanks!

CDN for SEO (or not)?
Does CDN impact on SEO or not? There seems conflicting ideas as to whether they impact positively or negatively, I realise that if the page loads quicker this is a good thing for SEO and usability of course. Does Google see CDN as just cheating and a get-around for not doing the work from the ground up and using good hosting etc? Do you have any direct experience? All constructive input much appreciated!

Should I use **tags or h1/h2 tags for article titles on my homepage**
I recently had an seo consultant recommend using tags instead of h1/h2 tags for article titles on the homepage of my news website and category landing pages. I've only seen this done a handful of times on news/editorial websites. For example: http://www.muscleandfitness.com/ Can anyone weigh in on this?

Link Age as SEO factor?
Hi Guys
Intermediate & Advanced SEO | Jun 23, 2011, 4:27 PM | VividLime
I have a client who ranks well within a competitive sector of the travel industry. They are planning CMS move which will involve changing from .cfm to .aspx We will be doing the standard redirects etc However Matt's statement here on 301 redirects got me thinking
http://www.youtube.com/watch?v=zW5UL3lzBOA&t=0m24s He says that basically you loose a bit of page rank when you do a 301 redirect. Now, we will be potentially redirecting 1000s of links and my thinking is 'a lot of a little, adds up to a lot' In other words, 1000s of redirects may have a big enough impact to loose some rankings in a very competitive and aggressive space. So recommended that we contact the sites who has the link highest value and ask them to manually change the links from cfm to aspx. This will then mean that there are no loss value as with a 301 redirect. -But now I have another dilemma which I'm unsure about. So the main question:
Is link age factor in rankings ? If I update any links, this will make said link new to Google, so if link age is a factor, would this also lessen the value passed initially?0
