Will Google Count Links Loaded from JavaScript Files After the Page Loads
-
Hi,
I have a simple question. If I want to put an image with a link to another site like a banner ad on my page, but do not want it counted by Google. Can I simply load the link and banner using jQuery onload from a separate .js file?
The ideal result would be for Google to index a script tag instead of a link.
-
Good Answer. I completely abandoned the banner I was thinking of using. It was from one of those directories that will list your site for free if you show their banner on your site. Their code of course had a link to them with some optimized text. I was looking for a way to display the banner without becoming a link farm for them.
Then I just decided that I did not want that kind of thing on my site even if it is in a javascript onload event if Google is going to crawl it anyway, so I just decided not to add it.
Then I started thinking about user generated links. How could I let people cite a source in a way that the user can click on without exposing my site to hosting spammy links. I originally used an ASP.Net linkbutton with a confirm button extender from the AJAX Control ToolKit that would display the url and ask the user if they wanted to go there. Then they would click the confirm button and be redirected. The problem was that the URL of the page was in the head part of the DOM.
I replaced that with a feature using a modal popup that calls a javascript function when the link button is clicked. That function then makes an ajax call to a webservice that gets the link from the database. Then the javascript writes an iframe to a div in the modal's panel. The result should be the user being able to see the source without leaving the site, but a lot of sites appear to be blocking the frame by using stuff like X-Frame-Options, so I'm probably going to use a different solution that uses the modal without the iframe. I am thinking of maybe using something like curl to grab content from the page to write to the modal panel along with a clickable link. All of this of course after the user clicks the linkbutton so none of that will be in the source code when the page loads.

I think what we really need to understand is, what is the purpose of hiding the link from Google? If it's to prevent the discovery of a URL or prevent the indexation of a certain page (or set of pages) - it's easier to achieve the same thing by using Meta no-index directives or wildcard-based robots.txt rules
or by simply denying Gooblebot's user-agent, access to certain pages entirely
Is is that important to hide the link, or is it that you want to prevent access to certain URLs from within Google's SERPs? Another option is obviously to block users / sessions referred from Google (specifically) from accessing the pages. There's lots can be done, but a bit of context would be cool
By the way, no-follow does not prevent Google from following links. It actually just stops PageRank from passing across. I know, it was named wrong
-
What about a form action? Where instead of an a element with a href attribute you add a form element with an action attribute to what the href would be in a link.
-
Thanks for that answer. You obviously know a lot about this issue. I guess they would be able to tell if the .js script file creates an a element with a specific href attribute and then add that element to a specific div tag after the page loads.
It sounds like it might be easier just to nofollow those links instead of going to all the trouble to redirect the .js file whenever Google Bot crawls the page. I fear that could be considered cloaking.
Another possibility would be a an alert that requires a user interaction before grabbing a url from a database. The user would click on the link without an href, the javascript onclick fires, the javascript grabs the the url from a database, the user is asked to click a button if they want to proceed, and then the user is redirected to the external url. That should keep the external URL out of the script code.

Google can crawl JavaScript and its contents, but most of the time they are unlikely to do so. In order to do this, Google has to do more than just a basic source code scrape. Like everyone else seeking to scrape data from inside of generated elements, Google has to actually check the modified source-code, after all of the scripts have run (the render) rather than the base (non-modified) source code before any scripts fire
Google's mission is to index the web. There's no doubt that, non-rendered crawls (which do not contain the generated HTML output of scripts) can be done in a fraction of the time it takes to get a rendered snapshot of the page-code. On average I have found rendered crawling to take 7x to 10x longer than basic source scraping
What we have found is that Google are indeed, capable of crawling generated text and links and stuff... but they won't do this all the time, or for everyone. Those resources are more precious to Google and they crawl more sparingly in that manner
If you deployed the link in the manner which you have described, my anticipation is that Google would not notice or evaluate the link for a month or two (if you're not super popular). Eventually, they would determine the presence of the link - at which point it would be factored and / or evaluated
I suppose you could embed the script as a link to a '.js' module, and then use Robots.txt to ban Google from crawling that particular JavaScript file. If they chose to obey that directive, the link would pretty much remain hidden from them. But remember, it's only a directive!
If you wanted to be super harsh you could block Googlebot (user agent) from that JS file and do something like, 301 them to the homepage when they tried to access it (instead of allowing them to open and read the JS file). That would be pretty hardcore but would stand a higher chance of actually working
Think about this kind of stuff though. It would be pretty irregular to go to such extremes and I'm not certain what the consequences of such action(s) would be

Hello, Smart People!
On-Page Optimization | | Viktoriia1805
We need help solving the problem with Google indexing.
All pages of our website are crawled and indexed. All pages, including those mentioned, meet Google requirements and can be indexed. However, only this page is still not indexed.
Robots.txt is not blocking it.
We do not have a tag "nofollow"
We have it in the sitemap file.
We have internal links for this page from indexed pages.
We requested indexing many times, and it is still grey.
The page was established one year ago.
We are open to any suggestions or guidance you may have. What else can we do to expedite the indexing process?1 -
Google ranking content for phrases that don't exist on-page
I am experiencing an issue with negative keywords, but the “negative” keyword in question isn’t truly negative and is required within the content – the problem is that Google is ranking pages for inaccurate phrases that don’t exist on the page. To explain, this product page (as one of many examples) - https://www.scamblermusic.com/albums/royalty-free-rock-music/ - is optimised for “Royalty free rock music” and it gets a Moz grade of 100. “Royalty free” is the most accurate description of the music (I optimised for “royalty free” instead of “royalty-free” (including a hyphen) because of improved search volume), and there is just one reference to the term “copyrighted” towards the foot of the page – this term is relevant because I need to make the point that the music is licensed, not sold, and the licensee pays for the right to use the music but does not own it (as it remains copyrighted). It turns out however that I appear to need to treat “copyrighted” almost as a negative term because Google isn’t accurately ranking the content. Despite excellent optimisation for “Royalty free rock music” and only one single reference of “copyrighted” within the copy, I am seeing this page (and other album genres) wrongly rank for the following search terms: “free rock music”

“Copyright free rock music"
“Uncopyrighted rock music”
“Non copyrighted rock music” I understand that pages might rank for “free rock music” because it is part of the “Royalty free rock music” optimisation, what I can’t get my head around is why the page (and similar product pages) are ranking for “Copyright free”, “Uncopyrighted music” and “Non copyrighted music”. “Uncopyrighted” and “Non copyrighted” don’t exist anywhere within the copy or source code – why would Google consider it helpful to rank a page for a search term that doesn’t exist as a complete phrase within the content? By the same logic the page should also wrongly rank for “Skylark rock music” or “Pretzel rock music” as the words “Skylark” and “Pretzel” also feature just once within the content and therefore should generate completely inaccurate results too. To me this demonstrates just how poor Google is when it comes to understanding relevant content and optimization - it's taking part of an optimized term and combining it with just one other single-use word and then inappropriately ranking the page for that completely made up phrase. It’s one thing to misinterpret one reference of the term “copyrighted” and something else entirely to rank a page for completely made up terms such as “Uncopyrighted” and “Non copyrighted”. It almost makes me think that I’ve got a better chance of accurately ranking content if I buy a goat, shove a cigar up its backside, and sacrifice it in the name of the great god Google! Any advice (about wrongly attributed negative keywords, not goat sacrifice ) would be most welcome.0 -
Why are http and https pages showing different domain/page authorities?
My website www.aquatell.com was recently moved to the Shopify platform.  We chose to use the http domain, because we didn't want to change too much, too quickly by moving to https.  Only our shopping cart is using https protocol.  We noticed however, that https versions of our non-cart pages were being indexed, so we created canonical tags to point the https version of a page to the http version.  What's got me puzzled though, is when I use open site explorer to look at domain/page authority values, I get different scores for the http vs. https version.  And the https version is always better.  Example:  http://www.aquatell.com DA = 21 and https://www.aquatell.com DA = 27.  Can somebody please help me make sense of this?  Thanks,

Listing all services on one page vs separate pages per service
My company offers several generalized categories with more specific services underneath each category. Currently the way it's structured is if you click "Voice" you get a full description of each voice service we offer. I have a feeling this is shooting us in the foot. Would it be better to have a general overview of the services we offer on the "Voice" page that then links to the specified service? The blurb about the service on the overview page would be unique, not taken from the actual specific service's page.

Home page and category page target same keyword
Hi there, Several of our websites have a common problem - our main target keyword for the homepage is also the name of a product category we have within the website. There are seemingly two solutions to this problem, both of which not ideal: Do not target the keyword with the homepage. However, the homepage has the most authority and is our best shot at getting ranked for the main keyword. Reword and "de-optimise" the category page, so it doesn't target the keyword. This doesn't work well from UX point of view as the category needs to describe what it is and enable visitors to navigate to it. Anybody else gone through a similar conundrum? How did you end up going about it? Thanks Julian

How many outbound links is too many outbound links?
As a part of our SEO strategy, we have been focusing on writing several high quality articles with unique content.  In these articles we regularly link to other websites when they are high quality, authoritative sites. Typically, the articles are 500 words or more and have 3-5 outbound links, but in some cases there are as many as 7 or 8 outbound links. Before we get too carried away with outbound links, I wanted to get some opinions on how many outbound links we should be trying to include and more information on how the outbound links work. Do they pass our website's authority on to the other website? Could our current linking strategy cause future SEO problems?  Finally, do you have any suggestions for guidelines we should be using? Thank you for your help!
