Being the standard language, HTML is always given preference by the search engines since they have designed their crawlers to recognize HTML tags mainly.However,with the advancement of web technology and e-commerce, there has been increase in the number of languages which are used for web development.
However, at the same time these languages(not all) have some adverse effects on SEO.As an SEO company, it is very mandatory for us to understand these consequenses and act accordingly.
Below are the scripts which an SEO company should avoid for SEO of any website:
Although flash websites look very appealing to all the users and give them opportunity to play with it,flash driven websites are not considered good for any website's search engine optimization(SEO).Due to the inability of Search engines crawlers to recognize flash content,this kind of website is not loved by search engines. Moreover the size of these flash websites also becomes very huge which has made them unflavored for search engines.SEO companies must take a note here that recently,Google has officially announced that it will consider weight of the webpages as one of the factors for ranking websites.
Active Server Pages (ASP)
Dynamic ASP scripting language is a server side scripting language which returns the values to the user dynamically,therefore again search engine crawlers don't find any information from these (about to load)pages as these kind of pages return values only when users request for it.So,all the SEO companies should take care while deciding for script language for the websites that need to be promoted/optimized.
I hope above information would be helpful for all SEO consultants/SEO companies who wonder sometimes why they find problems to rank Flash/ASP based websites.
