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 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.

Default Wordpress 301 Redirects of JS and CSS files. Bad for SEO & How to Fix?
Hi there: We are developers with some digital marketing expertise, but a current issue has us perplexed. An outside SEO firm has asked us to clean up a large number of 301 redirects. Most of these are 'default' Wordpress behavior that relate to calling the latest version of a JS or CSS file. For instance, a JS file is called with this: https://websitexyz.com/wp-includes/js/wp-embed.min.js?ver=4.9.1 but ultimately redirects to this: https://websitexyz.com/wp-includes/js/wp-embed.min.js. We are being asked to prevent the redirect from happening by, presumably, calling the ultimate file to begin with. The issue is that, as far as we know, there's no easy way to alter WP behavior to call the ultimate file to begin with. Does anyone have any thoughts on this? Thanks.

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.

Does collapsing content impact Google SEO signals?
Recently I have been promoting custom long form content development for major brand clients. For UX reasons we collapse the content so only 2-3 sentences of the first paragraph are visible. However there is a "read more" link that expands the entire content piece.

I have believed that the searchbots would have no problem crawling, indexing and applying a positive SEO signal for this content. However I'm starting to wonder. Is there any evidence that the Google search algorithm could possible discount or even ignore collapsed content?1 -
How does the use of Dynamic meta tags effect SEO?
I'm evaluating a new client site which was built buy another design firm. My question is they are dynamically creating meta tags and I'm concerned that it is hurting their SEO. When I view the page source this is what I see. <meta name="<a class="attribute-value">keywords</a>" id="<a class="attribute-value">keywordsGoHere</a>" content="" /> <meta name="<a class="attribute-value">description</a>" id="<a class="attribute-value">descriptionGoesHere</a>" content="" /> <title id="<a class="attribute-value">titleGoesHere</a>">title> To me it looks like the tags are not being added to the page, however the title is showing when you view it in a browser and if use a spider view tool, it sees the title. I'm guess it is being called from a DB. So I'm a little concerned though that the search engines are not really seeing the title and description. I'm not worried about the keywords tag. Can anyone shed some light on how this might work? Why it might not being showing the text for the description in the page code and if that will hurt SEO? Thanks for the help!

Do I need to use rel="canonical" on pages with no external links?
I know having rel="canonical" for each page on my website is not a bad practice... but how necessary is it for pages that don't have any external links pointing to them? I have my own opinions on this, to be fair - but I'd love to get a consensus before I start trying to customize which URLs have/don't have it included. Thank you.

Do links to PDF's on my site pass "link juice"?
Hi, I have recently started a project on one of my sites, working with a branch of the U.S. government, where I will be hosting and publishing some of their PDF documents for free for people to use. The great SEO side of this is that they link to my site. The thing is, they are linking directly to the PDF files themselves, not the page with the link to the PDF files. So my question is, does that give me any SEO benefit? While the PDF is hosted on my site, there are no links in it that would allow a spider to start from the PDF and crawl the rest of my site. So do I get any benefit from these great links? If not, does anybody have any suggestions on how I could get credit for them. Keep in mind that editing the PDF's are not allowed by the government. 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!
