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.

Can I add external links to my sitemap?
Hi, I'm integrating with a service that adds 3rd-party images/videos (owned by them, hosted on their server) to my site. For instance, the service might have tons of pictures/videos of cars; and then when I integrate, I can show my users these pictures/videos about cars I might be selling. But I'm wondering how to build out the sitemap--I would like to include reference to these images/videos, so Google knows I'm using lots of multimedia. How's the most white-hat way to do that? Can I add external links to my sitemap pointing to these images/videos hosted on a different server, or is that frowned upon? Thanks in advance.

Multiple H2 tags
Is it advisable to use only one H2 tag? The template designs for some reason is ended up with multiple H2 tags, I realise if any think it's that each one is that are important and it is all relative. Just trying to assess if it's worth the time and effort to rehash the template. Has anyone done any testing or got any experience? Thanks

Should I add no-follow tags to my widget links?
Matt Cutts recommended in a video in 2013 to add rel="nofollow" on widget links that link back to your website. Some background of my company: We're a software company for website chat. There's a 'powered by' link in our widgets that links back from our users' websites to our website. Currently these are all follow links. I checked out the links of our competitors, and it seems none of them have no follow on their widget backlinks. This, together with the fact that the video is quite old and information on this issue rather scarce, makes me doubt whether we should change our widget backlinks to no follow. Does anyone have thoughts on this?

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.

Do I have to many internal links which is diluting link juice to less important pages
Hello Mozzers, I was looking at my homepage and subsequent category landing pages on my on my eCommerce site and wondered whether I have to many internal links which could in effect be diluting link juice to much of the pages I need it to flow. My homepage has 266 links of which 114 (43%) are duplicate links which seems a bit to much to me. One of my major competitors who is a national company has just launched a new site design and they are only showing popular categories on their home page although all categories are accessible from the menu navigation. They only have 123 links on their home page. I am wondering whether If I was to not show every category on my homepage as some of them we don't really have any sales from and only concerntrate on popular ones there like my competitors , then the link juice flowing downwards in the site would be concerntated as I would have less links for them to flow ?... Is that basically how it works ? Is there any negatives with regards to duplicate links on either home or category landing page. We are showing both the categories as visual boxes to select and they are also as selectable links on the left of a page ? Just wondered how duplicate links would be treated? Any thoughts greatly appreciated thanks Pete

Do 404 Pages from Broken Links Still Pass Link Equity?
Hi everyone, I've searched the Q&A section, and also Google, for about the past hour and couldn't find a clear answer on this. When inbound links point to a page that no longer exists, thus producing a 404 Error Page, is link equity/domain authority lost? We are migrating a large eCommerce website and have hundreds of pages with little to no traffic that have legacy 301 redirects pointing to their URLs. I'm trying to decide how necessary it is to keep these redirects. I'm not concerned about the page authority of the pages with little traffic...I'm concerned about overall domain authority of the site since that certainly plays a role in how the site ranks overall in Google (especially pages with no links pointing to them...perfect example is Amazon...thousands of pages with no external links that rank #1 in Google for their product name). Anyone have a clear answer? Thanks!

Is it better "nofollow" or "follow" links to external social pages?
Hello, I have four outbound links from my site home page taking users to join us on our social Network pages (Twitter, FB, YT and Google+). if you look at my site home page, you can find those 4 links as 4 large buttons on the right column of the page: http://www.virtualsheetmusic.com/ Here is my question: do you think it is better for me to add the rel="nofollow" directive to those 4 links or allow Google to follow? From a PR prospective, I am sure that would be better to apply the nofollow tag, but I would like Google to understand that we have a presence on those 4 social channels and to make clearly a correlation between our official website and our official social channels (and then to let Google understand that our social channels are legitimate and related to us), but I am afraid the nofollow directive could prevent that. What's the best move in this case? What do you suggest to do? Maybe the nofollow is irrelevant to allow Google to correlate our website to our legitimate social channels, but I am not sure about that. Any suggestions are very welcome. Thank you in advance!
