      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

              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.

                        How Many Links to Disavow at Once When Link Profile is Very Spammy?

                        We are using link detox (Link Research Tools) to evaluate our domain for bad links. We ran a Domain-wide Link Detox Risk report. The reports showed a "High Domain DETOX RISK" with the following results: -42% (292) of backlinks with a high or above average detox risk
                        -8% (52) of backlinks with an average of below above average detox risk
                        -12% (81) of backlinks with a low or very low detox risk
                        -38% (264) of backlinks were reported as disavowed. This look like a pretty bad link profile. Additionally, more than 500 of the 689 backlinks are "404 Not Found", "403 Forbidden", "410 Gone", "503 Service Unavailable". Is it safe to disavow these? Could Google be penalizing us for them> I would like to disavow the bad links, however my concern is that there are so few good links that removing bad links will kill link juice and really damage our ranking and traffic. The site still  ranks for terms that are not very competitive. We receive about 230 organic visits a week. Assuming we need to disavow about 292 links, would it be safer to disavow 25 per month while we are building new links so we do not radically shift the link profile all at once? Also, many of the bad links are 404 errors or page not found errors. Would it be OK to run a disavow of these all at once? Any risk to that? Would we be better just to build links and leave the bad links ups? Alternatively, would disavowing the bad links potentially help our traffic? It just seems risky because the overwhelming majority of links are bad.

                        SEO friendly H1 tag with 2 text lines

                        Hi everyone, I am trying to add span tags in H1, break tag on 2 lines and style each line of H1 differently: Example: Line 1Line 2 I might add a smaller font for line 2 as well... Is this SEO friendly? Will crawlers read entire text or can interfere and block it. Thank you!

                        SEO Advice for Angular JS

                        We are changing our homepage (and gradually the rest of the site) to Angular JS.
                        In order not to lose anything in terms of SEO we are implementing Hashbangs + escaped fragment snapshots. Are there any other SEO considerations you think we should have and/or additional elements that we could add to the page to improve it in terms of SEO?

                        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 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!

                        Site wide footer links vs. single link for websites we design

                        I’ve been running a web design business for the past 5 years, 90% or more of the websites we build have a “web design by” link in the footer which links back to us using just our brand name or the full “web design by brand name” anchor text. I’m fully aware that site-wide footer links arent doing me much good in terms of SEO, but what Im curious to know is could they be hurting me? More specifically I’m wondering if I should do anything about the existing links or change my ways for all new projects, currently we’re still rolling them out with the site-wide footer links. I know that all other things being equal (1 link from 10 domains > 10 links from 1 domain) but is (1 link from 10 domains > 100 links from 10 domains)? I’ve got a lot of branded anchor text, which balances out my exact match and partial match keyword anchors from other link building nicely. Another thing to consider is that we host many of our clients which means there are quite a few on the same server with a shared IP. Should I? 1.) Go back into as many of the sites as I can and remove the link from all pages except the home page or a decent PA sub page- keeping a single link from the domain. 2.) Leave all the old stuff alone but start using the single link method on new sites. 3.) Scratch the site credit and just insert an exact-match anchor link in the body of the home page and hide with with CSS like my top competitor seems to be doing quite successfully. (kidding of course.... but my competitor really is doing this.)
