Search engines use their own ways to crawl and interpret the web contents, what we see in a webpage doesn’t look same to a search engine. In this article, we will discuss some of the key factors that need to be considered while building a SEO friendly website.
Follow W3C Standards:Designs must be given more importance, but it’s basically the back-end code that provides proper support. Therefore, try optimizing the code and checking for W3C compliance from the very beginning.
Don’t forget the basics including title tags, Meta tags, Meta descriptions, Header tags etc.
Don’t create directories further than three levels down from the root directory
The closer pages are to the home page in the directory structure the better. Keep things organized but don’t overorganize. If you have one file or sub-directory in a directory there should be a VERY valid reason.
Inner Page URL:each & every inner pages should contain keywords.
File/Directory Names Using Keywords:Your filenames and directory names should contain keywords. If your page is about Design Tips then the file name should be design-tips.
Hyphens:Use hyphens ( – ) and not underscores ( _ ) to separate words in directory and file names. Most search engines parse a hyphen like a reader would parse a space.
you should always put your CSS and other scripts in the external style sheets that are much easier to load.
Don’t forget to optimize your website images using alt tags. Also make sure to optimize the image size and loading time to the minimum.To explain all the images or pictures make sure you use Alt tags.Because search engines cannot identify images as words, therefore, you should use text instead of images for words and content.
Place Scripts Outside of the HTML Document
Use the keyword phrase in your URL
Use your keyword phrase in anchor text of links
Increase the font size of your keyword phrase
Use Heading Tags Properly
Don't use session IDs (AVOID)
Don't use frames (AVOID)
Don't Hide Text
Never include invisible text on your pages
Never link invisible images
Use existing social networks. Adding Facebook likes, Twitter,LinkedIn and Google Plus buttons etc.
Search engines have a really tough time crawling a website that uses Flash.
For designers, it is important to know that Flash can’t be completely indexed
If you must use Flash, always include alternative text Flash and search engines don't mix well, but if you must use flash you should include alternate text that describes exactly what the Flash element includes. And if you use Flash for your entire site, you should always do an alternate version of the complete site in HTML so that search engines and non-Flash browsers can view it as well.
The smaller your Web pages are, the faster they load. A single page should be less than 15K (unless absolutely necessary) and the entire page including graphics should be less than 50K (unless absolutely necessary).
