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 entirelyIs 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

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 is my contact us page ranking higher than my home page?
Hello, It doesn't matter what keyword I put into Google (when I'm not signed in and have cleaned down my browsing history) the contact us page ranks higher than the home page. I'm not sure why this is, the home page has a higher page authority, more links and more social media shares, the website is an established one. When I have checked Google Analytics my home page gets more people landing on it than the contact us page. It looks like people are ignoring the contact us page and scrolling down until they find the home page. I'd appreciate any help or advice you might have. Thank you.

Noindex child pages (whose content is included on parent pages)?
I'm sorry if there have been questions close to this before... I've using WordPress less like a blogging platform and more like a CMS for years now... For content management purposes we organize a lot of content around Parent/Child page (and custom-post-type) relationships; the Child pages are included as tabbed content on the Parent page. Should I be noindexing these child pages, since their content is already on the site, in full, on their Parent pages (ie. duplicate content)? Or does it not matter, since the crawlers may not go to all of the tabbed content? None of the pages have shown up in Moz's "High Priority Issues" as duplicate content but it still seems like I'm making the Parent pages suffer needlessly... Anything obvious I'm not taking into consideration? By the by, this is my first post here @ Moz, which I'm loving; this site and the forums are such a great resource! Anyways, thanks in advance!

301 redirects from several sub-pages to one sub-page
Hi! I have 14 sub-pages i deleted earlier today. But ofcourse Google can still find them, and gives everyone that gives them a go a 404 error. I have come to the understading that this wil hurt the rest of my site, at least as long as Google have them indexed. These sub-pages lies in 3 different folders, and i want to redirect them to a sub-page in a folder number 4. I have already an htaccess file, but i just simply cant get it to work! It is the same file as i use for redirecting trafic from mydomain.no to www.mydomain.no, and i have tried every kind of variation i can think of with the sub-pages. Has anyone perhaps had the same problem before, or for any other reason has the solution, and can help me with how to compose the htaccess file? 🙂 You have to excuse me if i'm using the wrong terms, missing something i should have seen under water while wearing a blindfold, or i am misspelling anything. I am neither very experienced with anything surrounding seo or anything else that has with internet to do, nor am i from an englishspeaking country. Hope someone here can light up my path 🙂 Thats at least something you can say in norwegian...

Prevent link juice to flow on low-value pages
Hello there! Most of the websites have links to low-value pages in their main navigation (header or footer)... thus, available through every other pages. I especially think about "Conditions of Use" or "Privacy Notice" pages, which have no value for SEO. What I would like, is to prevent link juice to flow into those pages... but still keep the links for visitors. What is the best way to achieve this? Put a rel="nofollow" attribute on those links? Put a "robots" meta tag containing "noindex,nofollow" on those pages? Put a "Disallow" for those pages in a "robots.txt" file? Use efficient Javascript links? (that crawlers won't be able to follow)

E-Commerce product pages that have multiple skus with unique pages.
Hey Guys, With the recent farm/panda update from google i'm at a cross roads as to how I should optimize product pages for a project i'm working on for a client. My client sells tires and one particular tire brand can have up to 15 models and each model can have up to 30 sizes. IE: 'Michelin Pilot Sport Cup' comes in 15 different sizes. Each size will have it's unique product page and description bringing me to my question. Should I use the same description on every size? I do plan on writting unique content for each tire model however i'm not sure if I should do it for every size. After all the tire model description is the same for every size, each size doesn't carry any unique characteristics that I can describe. Thanks in advance!
