			<content:encoded><![CDATA[<p>I have spent the entire day trying to write a crawler to get the used cars data from Gaadi.com. I have been getting confusing information through out the day. Having spent more than 12 hours tweaking my own code, I just realized that <strong>the error is there in the source data itself!!!!!!!!</strong></p>
<p>Just check this link for used toyota cars in New delhi http://www.gaadi.com/usedcars/TOYOYA&#8211;New+Delhi and you will understand my frustration.</p>
<p>I have spent the last 12 hours with the basic assumption that my code must have the error. The problem was I used the maruti in new delhi section as the test page and it was working fine. Sometimes being modest can be so frustrating&#8230;. <img src='http://www.contacthello.com/blog/wp-includes/images/smilies/icon_sad.gif' alt=':(' class='wp-smiley' />  Anyways will have to resume work tomorrow morning.</p>
<p>The only positive development in the day has been the fact that my <a href="http://www.contacthello.com/usedbikes/" target="_blank">used bikes</a> section has started to get some user entries and it made its debut in google serp at #170 for the keyword second hand bikes <img src='http://www.contacthello.com/blog/wp-includes/images/smilies/icon_smile.gif' alt=':)' class='wp-smiley' />  That is not exactly great but anyways the great G has considered my site worthy of inclusion is worth celebration.</p>

			<content:encoded><![CDATA[<p>I had already written the code to crawl carwale.com. Just completed the code to crawl cartradeindia. The crawler is still working at the moment and collecting information.</p>
<p><strong>Issues faced and resolved<br />
</strong></p>
<ol>
<li>The same model is referred to as differently on carwale and cartradeindia. E.g &#8216;Maruti&#8217; in Cartradeindia while &#8216;Maruti Suzuki&#8217; in carwale</li>
<li>Prices and KMs run are in text format in cartradeindia. Made use of simple text replace function to get rid of the commas. Making use of number_format function to display those beautiful numbers on search results page.</li>
<li>Original date of registration was too difficult to get on cartradeindia. It was going to consume too much of resources. Dropped from the frontend for now. Will add later if there is enough demand.</li>
</ol>
<p><strong>What next</strong></p>
<p>I have to add the next 7-8 used cars site to the search engine.</p>
<p>Till now the search is happening through form posts. I shall need to replicate the functionality through get function as well. This will enable those city specific pages like <strong><a href="http://www.contacthello.com/usedcars/index.php?city=Mumbai" target="_blank">used cars in Mumbai</a></strong> to start working.</p>
<p>I got several new listing on my <a title="used bikes" href="http://www.contacthello.com/usedbikes/" target="_blank">used bikes</a> website. I am excited about taking on the existing competition. Will need to spend some time cleaning up the confusing title structure.</p>

			<content:encoded><![CDATA[<p>I am a strong believer in the growth potential of India in the years to come. As India progresses there are 2 things that will happen</p>
<ul>
<li>More and more people will buy and sell second hand goods</li>
<li>More of those trades will start to happen on the internet.</li>
</ul>
<p>That is the belief on which contacthello.com was started. In the last 1 year I have made considerable progress in the <a href="http://www.contacthello.com/mobiles/">second hand mobiles</a> market with contacthello ranking among the top 10 results in Google for most of the terms. The traffic is still negligible but I am confident that it will improve dramatically over the next 12-18 months. There are many additional feature that needs to be added but not now. I am going to let the mobile section sustain on its own for the next 4 months and will look at adding any new feature after that only.</p>
<p>The other 2 goods with a significant market for used good are bikes and cars. The <a href="http://www.contacthello.com/usedbikes/">second hand bikes</a> section was added to the site at the beginning of this month. The code and UI is an exact copy of what was used for the mobiles section. While not much action is required on the development front, I need to do the initial bit of promotion to start getting bikes listed on the site. The section needs a sitemap badly.</p>
<p>The <a href="http://www.contacthello.com/usedcars/">used cars</a> section is a work in progress. Unlike the other 2 sections, it is not going to be a classified site. Rather I intend to develop it as a vertical search engine. I have already written the code to crawl carwale.com and the data is live on the site. Over this weekend I shall add code to crawl 5-6 more used cars sites. This is the first time I am creating a technically complex project. Hope I succeed and people like what they see.</p>
<p>The immediate task for october are</p>
<ol>
<li>Complete the development of the used cars and used bikes sections</li>
<li>Integrate the 3 sections more closely</li>
<li>Make the creation of sitemaps completely automated</li>
</ol>
<p>November is reserved for reaching out to bloggers interested in cars/bikes and/or mobiles. I have been pathetic on this front. Hopefully I will do better this time as there is no other alternative.</p>
