      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.

                        SEO value of affiliate external links

                        There are websites that have linked to my site. Whenever I hover over link I see my direct website URL and I am not seeing "no follow" when viewing source code so I assume these are passing link juice. However when I click on link it directs briefly to shareasale (affiliate account) in web address bar, but then quickly directs back to my website URL as directed. I was curious if these good links I am acquiring truly pass juice or since they briefly pass through an affiliate site if that cancels or dilutes the link juice. Also I am noticing when inspecting element that after the HREF it says class="external-link" I am just not sure if my link building efforts are being ruined by having an affiliate account running.I did not tell them I had one. I guess they are searching to see that I have one and trying to make a few extra commission dollars.

                        Onsite SEO vs Offsite SEO

                        Hey I know the importance of both onsite & offsite, primarily with regard to outreach/content/social. One thing I am trying to determine at the moment, is how much do I invest in offsite. My current focus is to improve our onpage content on product pages, which is taking some time as we have a small team. But I also know our backlinks need to improve. I'm just struggling on where to spend my time. Finish the onsite stuff by section first, or try to do a bit of both onsite/offsite at the same time?

                        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!

                        How do 302 redirects from Akamai content targeting impact SEO?

                        How do 302 redirects from Akamai content targeting impact SEO? I'm using Akamai content targeting to get people from countries and languages to the right place (eg www.abc.123 to redirect to www.abc.123/NL-nl/default.aspx where folks from the Netherlands get their localized site in dutch) and from the edge server closest to them.  As far as I know Akamai doesn't allow me to use anything but a 302.  Anyone run across this?  is this 302 a problem?  I did a fetch as googlebot on my main domain and all I see is the Akamai 302.  I can't imagine this is the first time Akamai has run across this but I would like to know for sure.

                        If we have pages on our site that link to search results is that a bad thing? Should we set the links to "nofollow"?
