SEO Impact of External links in JS tag

[kvivek05]

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 ?

**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

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.
