Trying to avoid duplicate content in my blog

Posted by Nishanth in web development on March 1st, 2009

After watching video about Canonical link element By Matt Cutts , I analyzed my site for possible duplicate content. I found that there are some pages having duplicate content.

I had listed these pages below:

  1. Article listing based on tags and article detail page. This happens when there is only one article inside a tag.
  2. Article listing based on category and article detail page. This happens when there is only one article inside a category.

I started searching for word press plug-in. One plug-in I found was adding canonical link to page and post. The plug-in was named “No duplicate content”. What it does is adding canonical link element for single page and post.

<link rel="canonical" href="YOUR_PREFERED_URL"/>

For my blog I don’t need a canonical link element in article detail page. There is no chance of duplicate content for article detail page. The only url I am providing to search engines is the permalink of the page.

In category/tag page I found an alternative way to avoid duplicate content. I wrote a small script for permanent redirect (301) in category/tag page. The redirect is conditional the page will be redirected if there is only one post inside category/tag page.

add_action ( "template_redirect", "canonicalLink");
function canonicalLink() {
	global $wp_query;
	$postCount = count($wp_query->posts);
	if((is_category()|| is_tag()) && $postCount==1) {
	 return wp_redirect(get_permalink($wp_query->posts[0]->ID),301);
	}
	return ;
}

I am experimenting with my blog, so I will be checking whether this script have any difference with Google indexing.

Files to edit for enabling cURL in XAMPP?

Posted by Nishanth in web development on February 19th, 2009

Last week I was installing “Magento” on XAMPP . Then I realized that cURL was disabled by default in XAMPP. I changed   “\apache\php\php.ini” and uncommented the line for cURL extension but still not working. Finally I made it working by editing couple of “ini” files. I had listed these ini’s below.

\xampp\apache\bin\php.ini
\xampp\apache\php\php5.ini
\xampp\apache\php\php.ini
\xampp\apache\php\php\php4.ini (to switch PHP version)

To enable cURL you need to uncomment the below line

;extension=php_curl.dll

to 

extension=php_curl.dll

This is a small script used for highlighting the current page’s navigation link. Here you can also specify the scope by just removing “*” with your own expression. Here I am adding class “current” to the navigation link wich can be used for styling the link.

$("*").find("a[href='"+window.location.href+"']").each(function(){
$(this).addClass("current")
//add your own logic here if needed
})

Is adsensebot helping googlebot with indexing?

Posted by Nishanth in web development on February 14th, 2009

I believe that Adsensebot is helping googlebot with indexing.

After registering my domain I had submitted my site to https://www.google.com/webmasters/.
I was constantly checking if the site was indexed by google. As site was not indexed by the google I started googling for SEO realted articles. I came across several blogs and read some articles regarding adsense bot.Finally I decided to put adsense in my site. The very next day I got my homepage indexed in Google.

Google has been using a shared cache So any page crawled by any Googlebot is stored in the cache, then any other bot can first check the cache before sending out a page request So this way adsensebot may help googlebot.
