The number of internet users are turning into publishers at a fastest rate, therefore you must be careful when applying a tutorial to your blog and extra careful when the tutorial talks of Jquery and SEO. I am observing baseless SEO tips coming from new bloggers that causes more harm to blogs at long term then a short term relief. Almost every new blogger has started sharing his own ideas of SEO and writing codes. This is surely encouraging but on the other side incorrect knowledge has caused several blogs to be hit by Google penalties such as Panda and Penguin.
Please let me know if you want any help here. I hope this technique would further help developers to create more interesting blogger templates and contribute further to the blogosphere community. I would love to hear your feedback on this. Please let us know of your precious views so that we could improve it further if needed.
