      Hello

      Client got website with javascript generated content. All links there (from mainpage to some deeper page) are js generated. In code there're only javascripts and other basic typical code but no text links (<a href...="" ).<="" p=""></a>

      <a href...="" ).<="" p="">The question is: are those js links got the same "seo power" as typical html href links?.For example majestic.com can't scan website properly and can't show seo metrics for pages. I know google crawls them (links and pages) but are they as good as typical links?</a>

      <a href...="" ).<="" p="">Regards,</a>

          Hi Krzysztof,

          Not too much information out there regarding how much link equity is passed through a javascript link, however, this study published by Branded3.com shows their evidence that 'pagerank' is passed through JavaScript redirects. Again, I don't know how much equity is being lost due to the JavaScript redirect (if any) but I imagine links would be treated in a similar manner.

            I think the same but need some more "proofs" like a/b tests or something.

              Hi Krzysztof,

              It's best practice for internal links to have href attributes. My understanding is although Google will be able to find internal links dependant on JavaScript, they're not treated the same, and that the passing of page rank will be negatively impacted.

                Link juice through URL parameters

                Hi guys, hope you had a fantastic bank holiday weekend. Quick question re URL parameters, I understand that links which pass through an affiliate URL parameter aren't taken into consideration when passing link juice through one site to another. However, when a link contains a tracking URL parameter (let's say gclid=), does link juice get passed through? We have a number of external links pointing to our main site, however, they are linking directly to a unique tracking parameter. I'm just curious to know about this. Thanks, Brett

                Do I have to many internal links which is diluting link juice to less important pages

                Hello Mozzers, I was looking at my homepage and subsequent category landing pages on my on my eCommerce site and wondered whether I have to many internal links which could in effect be diluting link juice to much of the pages I need it to flow. My homepage has 266 links of which 114 (43%) are duplicate links which seems a bit to much to me. One of my major competitors who is a national company has just launched a new site design and they are only showing popular categories on their home page although all categories are accessible from the menu navigation. They only have 123 links on their home page. I am wondering whether If I was to not show every category on my homepage as some of them we don't really have any sales from and only concerntrate on popular ones there like my competitors , then the link juice flowing downwards in the site would be concerntated as I would have less links for them to flow ?... Is that basically how it works ? Is there any negatives with regards to duplicate links on either home or category landing page. We are showing both the categories as visual boxes to select and they are also as selectable links on the left of a page ? Just wondered how duplicate links would be treated? Any thoughts greatly appreciated thanks Pete

                Do 404s really 'lose' link juice?

                It doesn't make sense to me that a 404 causes a loss in link juice, although that is what I've read.  What if you have a page that is legitimate -- think of a merchant oriented page where you sell an item for a given merchant --, and then the merchant closes his doors.  It makes little sense 5 years later to still have their merchant page so why would removing them from your site in any way hurt your site?  I could redirect forever but that makes little sense.  What makes sense to me is keeping the page for a while with an explanation and options for 'similar' products, and then eventually putting in a 404.  I would think the eventual dropping out of the index actually REDUCES the overall link juice (ie less pages), so there is no harm in using a 404 in this way.  It also is a way to avoid the site just getting bigger and bigger and having more and more 'bad' user experiences over time. Am I looking at it wrong? ps I've included this in 'link building' because it is related in a sense -- link 'paring'.

                Do 404 pages pass link juice? And best practices...

                Last year Google said bad links to 404 pages wouldn't hurt your site. Could that still be the case in light of recent Google updates to try and combat spammy links and negative SEO? Can links to 404 pages benefit a website and pass link juice? I'd assume at the very least that any link juice will pass through links FROM the 404 page? Many websites have great 404 pages that get linked to: http://www.opensiteexplorer.org/links?site=http%3A%2F%2Fretardzone.com%2F404 - that was the first of four I checked from the "60 Really Cool...404 Pages" that actually returned the 404 HTTP Status! So apologies if you find the word 'retard' offensive. According to Open Site Explorer it has a decent Page Authority and number of backlinks - but it doesn't show in Google's SERPs. I'd never do it, but if you have a particularly well-linked to 404 page, is there an argument for giving it 200 OK Status? Finally, what are the best practices regarding 404s and address bar links? For example, if
                www.examplesite.com/3rwdfs returns a 404 error, should I make that redirect to
                www.examplesite.com/404 or leave it as is? Redirecting to www.examplesite.com/404 might not be user-friendly as people won't be able to correct the URL in the address bar. But if I have a great  404 page that people link to, I don't want links going to loads of random pages do I? Is either way considered best practice? If I did a 301 redirect I guess it would send the wrong signal to the crawlers? Should I use a 302 redirect, or even a 304 Not Modified redirect?

                De-indexed Link Directory

                Howdy Guys, I'm currently working through our 4th reconsideration request and just have a couple of questions. Using Link Detox (www.linkresearchtools.com) new tool they have flagged up a 64 links that are Toxic and should be removed. After analysing them further alot / most of them are link directories that have now been de-indexed by Google. Do you think we should still ask for them to be removed or is this a pointless exercise as the links has already been removed because its been de-indexed. Would like your views on this guys.

                Maximum number of links

                Hi there, I have just written an article that is due to be posted on an external blog, the article has potentially 3 links that could link to 3 different pages on my website, is this too much? what do you recommend being the maximum number of links? Thanks for any help

                Noindex,follow is a waste of link juice?

                On my wordpress shopping cart plugin, I have three pages /account, /checkout and /terms on which I have added “noindex,follow” attribute.   But I think I may be wasting link juice on these pages as they are not to be indexed anyway, so is there any point giving them any link juice? I can add “noindex,nofollow” on to the page itself. However, the actual text/anchor link to these pages on the site header will remain “follow” as I have no means of amending that right now. So this presents the following two scenarios –   No juice flows from homepage to these 3 pages (GOOD) – This would be perfect then, as the pages themselves have nofollow attribute.   Juice flows from homepage to these pages (BAD) - This may mean that the juice flows from homepage anchor text links to these 3 pages BUT then STOPS there as they have “nofollow” attribute on that page. This will be a bigger problem and if this is the case and I cant stop the juice from flowing in, then ill rather let it flow out to other pages.   Hope you understand my question, any input is very much appreciated. Thanks

                Increasing Internal Links But Avoiding a Link Farm

                I'm looking to create a page about Widgets and all of the more specific names for Widgets we sell: ABC Brand Widgets, XYZ Brand Widgets, Big Widgets, Small Widgets, Green Widgets, Blue Widgets, etc. I'd like my Widget page to give a brief explanation about each kind of Widget with a link deeper into my site that gives more detail and allows you to purchase. The problem is I have a lot of Widgets and this could get messy: ABC Green Widgets, Small XYZ Widgets, many combinations. I can see my Widget page teetering on being a link farm if I start throwing in all of these combos. So where should I stop? How much do I do? I've read more than 100 links on a page being considered a link farm, is that a hardline number or a general guideline?
