Its seems like SEO has really got it's root deep in Kerala. The state which seems to be having less competition couple of years back has become very tough to rank for keywords with prefix and suffix SEO term. So kiddos to mallus.
I have seen that huge demand and competition in the cities like Bangalore and Chennai. Overall demand has come up in Cochin too.
More and more business are using the mordan way of marketing with introduction of smartphone this has shoot up.
When I started my career as SEO Analyst there was very few opening in this area and I was little worried about choosing this area. But now SEO has even taken its place in big MNC like Infosys , TCS, Cognizant, IBM, Robertbosh and others MNC . I know this because I myself is working for Infosys :) and my friends in companies I mentioned above.
What I really want to say is SEO is good field and there is lots of scope in Kerala .
There are many business which has need to come to online and they are not. So all the entrepreneur chase all the company who has not got into SEO and they will have to because this is world of online marketing.
