Now, let’s discuss briefly regarding these basic, healthy and powerful Technical SEO elements.

IP Redirection/Detection

IP Redirection/Detection is just the way of identifying the IP address of users and redirecting them to the right content based on their spot. For instance, if a user is from India and had landed in a website then it seems healthier if you redirect them to the appropriate content that is making them to land in which will contain the content related to India. Showing the right content based on the user’s location and language will make you to sound good in user’s mind and it may even make them to think about your content as 100% accurate.

Even though it seems good, it looks niggling for search engine crawlers as most of the crawlers today are based in the US. So, this type of redirection may even make your page to get hided from crawlers as sometimes there may difficulties in identifying the right IP. Most of the SEOs don’t know the risk of detecting and redirecting the IP and the problems that it would cause. So it would be better, if web developers convey this with the SEOs in order to avoid hiding the web pages from the search engines.

Faster Loading Web Pages

While developing websites, the first priority should be given to the site speed as it is the one which is going to make the customer to stay in the website for a longer period of time and as well as the best way to provide higher satisfaction to the customers. Google loves it users and users loves the websites with higher speed, so you should too. This just stay as the better way to earn enhanced ROI.

Redirects (301 and 302)

As a web developer, you could have already known well about all the redirects. But, here you only need to make use of only 301 and 302 redirects and not other redirects. 301 redirect are usually used just to imply that the URL has been moved permanently to other location that is to redirect the users and search engines to apposite new page.

This redirect usually helps in passing the link juice to the new URL. 302 redirect is just to imply that the page is moved temporarily. This won’t be permanent and won’t pass the link juice. Redirecting all the pages to the home page and as well to single top level category looks bad and manipulative. Most of the SEO’s and developers misunderstand this, so be clear with this and make use of only 301 and 302 redirect.

HTTP Header Codes

Almost every web developer would have known about header codes. Every code has its own effect and have separate outcome to influence the site’s performance. Below are few header codes that every SEO and web developer should know,

  • 200 implies Success
  • 301 implies Moved Permanently
  • 302 implies Moved Temporarily
  • 404 implies Page Not Found
  • 410 implies Page permanently not found
  • 500 implies internal server error
  • 503 implies Service unavailable

Access by Crawlers

It’s highly important for everyone to understand the way to handle the crawler. At the basic level, Google crawl websites based on the page rank in its decreasing order. It’s not possible for Google to crawl and index every web page automatically. So, it will be better if your website have good site architecture. Implement this and make Google to spend its time successfully by crawling the most important pages of website. To do this, it’s necessary to know certain techniques such as Robots.txt and Rel=Canonical.


Javascript is the one which append great functionality to the website to enhance the user experience. But, search engine struggle to understand Javascript. So, the search engine is actively trying to execute Javascript in order to access more content. While using Javascript in web development, it is highly necessary to be careful in two things. They are,

  • It is not recommended to place the important content in between the Javascript.
  • It is not advisable to hide the valuable content and links from Google by enclosing it in between Javascript.


Most of the web developers would have known well about Flash, but for the convenience it seems better to revise. Just like Javascript, search engine experience difficulties to understand flash elements. Google still find complexity in the advanced concepts of Flash, it can take out only little text and URL. It is better to develop a website with flash but how is it possible for the search engine to visit.

As title says, every web developer should know the above techniques to develop a better website for their clients or for their own. Hope, you all would have got some idea regarding some basic SEO techniques. If you have any suggestion regarding this, please do share with us.
