      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.

                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.

                Does google credit links from iFrames or created by Javascript, if so, is one more powerful than the other?

                Consider this example, because I want to be clear about what I mean.  You have two websites.  Lets all them www.a.com and www.b.com. On www.a.com/some/page, there is an iframe something like this:
                <iframe src="www.b.com/some/special/path"></iframe>
                Then content of this iframe is a bunch of pictures, text and numbers, as well as a group of links, linking each picture to www.b.com for example the links might be:
                www.b.com/content/1
                www.b.com/content/2
                www.b.com/content/3 Questions: When google crawls **www.a.com/some/page, **does it pass link juice to www.b.com/content/*? Does google instead consider these to be internal links within b.com itself.  because links to www.b.com/content/ ** are actually from b.com itself, since the domain of the iframe is actually: www.b.com/some/special/path 3) Is there any amount of link juice passed from www.a.com/some/page to* www.b.com/some/special/path **because this is the src= element of an iframe that a.com is hosting? Consider an alternative setup.  Where instead of using an iframe the contents of the above described iFrame is actually added the the page dynamically using javascript, and a call to an API endpoint at b.com.  Resulting in these links being added directly to the body of a.com without being wrapped in an iframe element. Questions:
                4) Do these links that were created after page load still get crawled and credited by google? (i have heard in the past that google was going to start crawling javascript, i just don't know if this is known for a fact yet).
                5) Do links created on the client side hold the same weight as a link that was served directly via the backend html generation? If both the links within the iframe and the links within the javascript embed method pass link juice.  Is one preferred over the other? is one known to be more effective than the other? Thanks!

                Does Disavowing Links Negate Anchor Text, or Just Negates Link Juice

                I'm not so sure that disavowing links also discounts the anchor texts from those links. Because nofollow links absolutely still pass anchor text values. And disavowing links is supposed to be akin to nofollowing the links. I wonder because there's a potential client I'm working on an RFP for and they have tons of spammy directory links all using keyword rich anchor texts and they lost 98% of their traffic in Pengiun 1.0 and haven't recovered. I want to know what I'm getting into. And if I just disavow those links, I'm thinking that it won't help the anchor text ratio issues. Can anyone confirm?

                Link Juice + multiple links pointing to the same page

                Scenario
                The website has a menu consisting of 4 links Home | Shoes | About Us | Contact Us Additionally within the body content we write about various shoe types. We create a link with the anchor text "Shoes" pointing to www.mydomain.co.uk/shoes In this simple example, we have 2 instances of the same link pointing to the same url location.
                We have 4 unique links.
                In total we have 5 on page links. Question
                How many links would Google count as part of the link juice model?
                How would the link juice be weighted in terms of percentages?
                If changing the anchor text in the body content to say "fashion shoes" have a different impact? Any other advise or best practice would be appreciated. Thanks Mark

                Does a 302 redirect pass penalties?

                I'm having problems finding a definitive answer to this question, there is a lot of rumour and gossip out there but nothing I can rely on. I'm working with a site that received an unnatural links notice followed by a massive drop in search traffic. Looking at the link profile it's pretty much jacked beyond repair and I have recommended that we move over to a fresh domain. However, it's an established brand with many more sources of traffic than organic search. There's no way we can burn all their repeat visits, loyal customers, brand recognition that they've built up over the years so I want to redirect from the old domain to the new.  This is not to try and make any SEO gain from the previous site, frankly we don't give a crap about that. We just want to maintain the brand. A 302 is a temporary redirect, this will be a permanent move BUT a 301 will pass on the penalty.  So can we safely use a 302 redirect in this situation or is there a better alternative (meta refresh?) Thanks for your help! MB.

                Can penalties be passed via 301 redirect?

                I have a well established domain that's been hit with some penalties. It hasn't been nuked off the map, just downgraded, especially on short-tail, one word type queries. I'm planning on redirecting this domain to another well established domain. The domains already have a history of lots of interlinking and are very similar from a subject matter standpoint. I feel that the penalized domain has been hit with an "over-optimization" of link anchor text penalty (I'm hoping it's algorithmic, but it could be manual). My question is if anyone has ever heard of a penalty like this being transferred to another domain through a 301 redirect. My hope is that the penalty just puts a cap on how much juice the redirect can pass, rather than transferring the penalty to the other domain itself. Any thoughts on this?

                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?

                Switching to masked affiliate links

                Hi there, I run a content affiliate website where I introduce products in articles and then link to merchants where the user can buy the respective product. Currently I am using regular affiliate links here with the "nofollow" attribute. With growing size of the site, I would like to switch to masked affiliate links, so instead of a link like "jdoqocy.com/click-123" I want to use "mydomain.com/recommend/123". My question here is: When switching to masked affiliate links, does it makes sense to also convert all the older unmasked affiliate links? If yes, what would be the best way to do that - Convert all old links at once or convert them over time (e.g. over a few month)? Currently about 2/3 of my site's outbound links are unmasked, external affiliate links. So I am afraid that changing this relatively large share of links from unmasked external affiliate links to masked links doenst look natural at all... Thank you for your advice!
