      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 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!

                        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?

                        Ecommerce Site homepage , Is it okay to have Links as H2 Tags as that is relevant to the page ?

                        Hi All, I have a Rental site and I am bit confused with how best do my H Tags on my homepage I know the H1 is the most important, Then H2 Tags and so on.. and that these tags should really be titles for content. However, I have a few categories (links) on my homepage so I am wondering if I could put these as H2 Tags given that it is relevant to the page . H3 Tags will my News and Guides etc , H4 Tags will the whats on the footer. I am attached a made up screenshot of what I propose for my homepage  if someone could please  give it a quick look ,  it would be very much appreciated. I have looked at what some competitors do a lot of them don't seem to have h2's etc but I know it's an important factor for rankings etc. Many thanks Pete dJSFQwI

                        Domain Forwarding - SEO Impacts?

                        I have a site that has been active for years - thinkbiglearnsmart.com. Awhile ago I had purchased about 50 domain names that were relevant to my company. I still have those urls and would like to use them to point to different pages on my site - just because they have good key words in the URLs. For example - one is dreamweavertrainingclassesonlinelive.com.  Currently they are all redirecting to my homepage. A. is that hurting me? B. I would like to redirect to the more relevant page. ie the page dedicated to Dreamweaver training (http://thinkbiglearnsmart.com/dreamweaver-creative-cloud-training-course/ ) Will this hurt my Dreamweaver keyword for example because there is already a 301 redirect on that page from a very old Dreamweaver link which was something like thinkbiglearnsmart.com/dreamweaver C. On my hosting account where I can select where the URL forwards to - it has an option for "Location forwarding" and "Frame forwarding" - currently they are set to Frame forwarding - which one is best? Any help is much appreciated!!! Thank you!

                        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!

                        Link Research Tools - Detox Links

                        Hi, I was doing a little research on my link profile and came across a tool called "LinkRessearchTools.com". I bought a subscription and tried them out. Doing the report they advised a low risk but identified 78 Very High Risk to Deadly (are they venomous?) links, around 5% of total and advised removing them. They also advised of many suspicious and low risk links but these seem to be because they have no knowledge of them so default to a negative it seems. So before I do anything rash and start removing my Deadly links, I was wondering if anyone had a). used them and recommend them b). recommend detoxing removing the deadly links c). would there be any cases in which so called Deadly links being removed cause more problems than solve. Such as maintaining a normal looking profile as everyone would be likely to have bad links etc... (although my thinking may be out on that one...). What do you think? Adam

                        tags inside <a>tags - is this bad?</a>

                        Hi, I'm currently redesigning my website, and in many places, I've now decided to make links a little bit more obvious for the user, using tags within a <a>tag in order to make the entire block of text clickable.  I was just wondering if this could have a negative impact in the search engines.  My gut feeling is no, since I'm actually improving usability, but I guess it could have an impact on how Google looks at the anchor text?  An example of the HTML is as follows: </a> <a></a> <a></a> [Cristal Night Club Hotels <address>1045 5th Street
                        Miami Beach, FL33139</address> 6.4 miles from Miami Dade County Auditorium](http://localhost:8080/frontend/venue-hotels/cristal-night-club-hotels/301022 "Hotels near Cristal Night Club") Thanks for your thoughts and comments, Best wishes Mike

                        Migrating online store to subdomain using shopify and effects on seo and energy down the road for seo

                        I'm looking for some clarity... Looking at using Shopify for an existing online store that we have to migrate. Setting up the store with shopify means we will be using a subdomain such as shop.mywebsite.com instead of mywebsite.com/shop. The following are points to consider when responding The client currently has an online store, however it's a proprietary shopping store and CMS that has since gone defunct and they need to migrate to an alternative in order to survive online against new CMS systems that allow the site and its content to be better optimized. There is a lot of existing SEO done on the current site that we don't want to loose PR on. There is roughly 2000 products Client has a fixed budget, dealing with checkout issues, custom work and various other "bugs" seems to be easier controlled with Shopify...thus budget can be used more on content/strategy and migration We want to run the main site in Wordpress and are wanting to use Shopify since it supports a gateway, has great features and seems like it would allow us to get more bang for the buck and can focus more on the main site and content strategy and drive traffic to the subdomain store if needed Or main concern is the effort of migrating 2000+ products to shopify and the traffic and PR it gives the current site will have a negative effect on the main domain itself. Should we really be considering this path? The domain is diveidc.com One main benefit to the subdomain is the ability to clearly segment products from the service portion of the site in the analytics and focus 2 clear strategies and track it in a very defined manner. We're really on the fence with this...any thoughts are welcome.
