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

Google Console returning 0 pages as being indexed
HI there, I submitted my site notebuster.net to Search Console over a month ago and it is showing 0 pages as being indexed under the index status report. I know this isn't right as I can see that in google alone by typing in (site:notebusters.net) there are 113 pages indexed. Any idea why this might be? Thanks

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.

Why does Google pick a low priority page on my site?
Hi Guys. One of my pages ranks quite well for "mid year diaries 14-15" on Google. The problem is it's a really specific product page (A4, Hardback, day-to-a-page diary I think). It would be much better for the user to land on our mid-year diaries category, not really deep into the site. Why is Google prioritizing this product page over our general 'mid year diaries' category? Especially when the category would relate to the search more accurately? I work for TOAD diaries and I think our page rank is 10 for this search. Eagerly awaiting some insight 🙂 Thanks in advance everyone! Isaac.

Home page or landing page?
Hello, I want to ask a question related to that - Should we put keywords in the home page title if we wish to position another landing page better for particular keywords? I have read in one website about SEO that it's good the main keywords of your website to be positioned in homepage title also. f.e. Let's say we have website about web-design and our company is named Company Ltd. The title of the home page is "Company Ltd. - Web design, SEO, etc" We have also another inner page named "Web design | Company Ltd.". So should we leave the first page name only "Company Ltd." and the landing page's name "Web design | Company Ltd." . I don't know if they both have the same keyword in their title they won't compete with each other.

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.?

Is there a SEO penalty for multi links on same page going to same destination page?
Hi, Just a quick note. I hope you are able to assist. To cut a long story short, on the page below http://www.bookbluemountains.com.au/ -> Features Specials & Packages (middle column) we have 3 links per special going to the same page.

1. Header is linked
2. Click on image link - currently with a no follow
3. 'More info' under the description paragraph is linked too - currently with a no follow Two arguments are as follows:
1. The reason we do not follow all 3 links is to reduce too many links which may appear spammy to Google. 2. Counter argument:
The point above has some validity, However, using no follow is basically telling the search engines that the webmaster “does not trust or doesn’t take responsibility” for what is behind the link, something you don’t want to do within your own website. There is no penalty as such for having too many links, the search engines will generally not worry after a certain number.. nothing that would concern this business though. I would suggest changing the no follow links a.s.a.p. Could you please advise thoughts. Many thanks Dave Upton [long signature removed by staff]0 -
Tag clouds: good for internal linking and increase of keyword relevant pages?
As Matt Cutts explained, tag clouds are OK if you're not engaged in keyword stuffing (http://www.youtube.com/watch?v=bYPX_ZmhLqg) - i.e. if you're not putting in 500 tags. I'm currently creating tags for an online-bookseller; just like Amazon this e-commerce-site has potentially a couple of million books. Tag clouds will be added to each book detail page in order to enrich each of these pages with relevant keywords both for search engines and users (get a quick overview over the main topics of the book; navigate the site and find other books associated with each tag). Each of these book-specific tag clouds will hold up to 50 tags max, typically rather in the range of up to 10-20. From an SEO perspective, my question is twofold: 1. Does the site benefit from these tag clouds by improving the internal linking structure? 2. Does the site benefit from creating lots of additional tag-specific-pages (up to 200k different tags) or can these pages become a problem, as they don't contain a lot of rich content as such but rather lists of books associated with each tag? Thanks in advance!

SEO value of "in the news" links on home page?
Notice more sites have an "in the News" section on the home page, or something similar like press releases... Apart from providing users fresh content, is there an SEO value to this? What is the explanation for this? Have a feeling the answer is obvious but just not too sure Thanks a lot.
