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

Does Google avoid indexing pages that include registered trademark signs?
I am suspecting that Google often hesitates to index pages that have registered trademarks on them that are marked with a ®. For example EGOL® used in the title tag or in the tag at the top of the page. Registered trademarks are everywhere and most retail product pages contain at least one of them. However, most people use the registered trademark names as text in their writing without adding the registered trademark sign of ®. Have you experienced a problem getting such pages indexed or have you read any articles about how Google treats registered trademarks?

How will it effect SEO to have multiple h1 tags on a page?
I have a client who recieved this advice from his marketing consultant: "If there are multiple h1 tags on a page, this can confuse Google and it may have a negative impact on the keyword rankings. If you could ask your web developer to go in and remove the h1 tags on the header images that would be helpful. This way it will be easier for Google to index your site and will help your keyword rankings." How will it effect SEO to have multiple h1 tags on a page?

In counting words for a "long article," do comments count in the word count?
As Moz and others have proven, long articles help ranking, linking and sharing. My question is, do the comments at the end of an article count in the word count as Google counts it.

Analyzing word count on page SEO
Hey guys quick question, when I am analyzing/ doing word count for a particluar key word and I want to make sure that i am no where near Keyword stuffing, does Google consider the alt and title tags keywords of images as part of the KW count when looking for on page Keyword stuffing. For example. let say I have a page that i just created with 1000 words. and Only 2 of the words are my target Keywords. Then, if i add a picture and add the keyword to both the alt and title tag and description of the image, does google now consider the "page" to have a total of 5 keywords? Also, a lot has changed recently since penguin and panda, is there a good rule of thumb for what ratio to stay under as far as keywords to text.?
