      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 ?

        <a class="zippy index13 goog-zippy-expanded" tabindex="0" name="10" data-tracking-impression=""></a>Anatomy of pre-fetch tags

        **https://ad.doubleclick.net**: These parameters are the same as in standard tags.

        **ddm: **This is a new parameter that distinguishes DCM tags from the legacy product (DFA). It makes no difference to how you export or implement your tags. Learn more

        **pfadx**: Lets the ad server know that this is a pre-fetch (pf) tag and an ad command for XML (adx).

        _Nxxxx.site-keyname/Byyyyyy_;kw=[keyword];ord=[timestamp];dc_lat=_N_;dc_rdid=_Czzzz_;tag_for_child_directed_treatment=_I_: These parameters are the same as in standard tags.

        **sz=_widthxheight_: **Dimensions of the placement, in pixels. (The value of the sz parameter is always 0x0 for VAST placements.)

        **dcmt=_text/xml_**: MIME stands for Multipurpose Internet Mail Extensions, which tell the browser what type of content you're sending. In this case, the MIME type is text/xml, which means that the content being sent is text in the form of XML code.

        **dc_vast=3**: Formats the tag to be compliant with VAST 3.0 specifications.

        theoretically you could pass a regular tag through there as well so hopefully that is of some help

          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

              http://searchengineland.com/tested-googlebot-crawls-javascript-heres-learned-220157

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

                      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.

                        Hi mozzers, We just redesigned our homepage and discovered that our main nav is using JS and when disabling JS, no main nav links was showing up. Is this still considered bad practice for SEO? https://cl.ly/14ccf2509478 thanks

                        Deep linking with redirects & building SEO

                        Hi there. I'm using deep linking with unique URL's that redirect to our website homepage or app (depending on whether the user accesses the link from an iphone or computer) as a way to track attribution and purchases. I'm wondering whether using links that redirect negatively affects our SEO? Is the homepage still building SEO rank despite the redirects? I appreciate your time & thanks for your help.

                        SEO impact of 301 redirects based on IP addresses from a specific state

                        Hello Moz Community! We are facing an issue that may or may not be unique, but need some advice and/or clarification on the best way to address the issue. We recently rebranded and launched a new site under a new domain and things have been progressing well.  However, despite all the up front legwork on trademarks and licensing, we have recently encountered a hiccup that forces us to revert to the old URL/branding for one specific state.  This may be a temporary issue that lasts a couple of months or it could potentially be in the court system for a couple of years. One potential solution we have discussed is to redirect the new site to the old site based on IP addresses for the state in question.  Looking for any guidance on what type of impact this may have on SEO.  Also open to any other suggestions or guidance on dealing with this situation. 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!

                        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.

                        Outbound link to PDF vs outbound link to page

                        If you're trying to create a site which is an information hub, obviously linking out to authoritative sites is a good idea. However, does linking to a PDF have the same effect? e.g Linking to Google's SEO starter guide PDF, as opposed to linking to a google article on SEO. Thanks!

                        If you have an unlimited SEO budget, what would you do?

                        Here's a bit of background information: I've achieved the targets and is now being offered what is essentially an unlimited budget. I have a nice list of ideas but thought I would the brilliant people here at the SEOMOZ community what they would do. So as to promote as much response as possible, I'm going to keep my list to myself for now. And by "SEO", I mean I can do things like content strategy, blogging, infographics, etc. Shoot away!
