Classified posting and Business directories are the best strategy for generate the leads to Search Engine Optimization.Apart from any strategies available for lead generation?
Yes, Classified is one of the best strategy to get the enquiries for the new websites but I don't know much about business directories giving enquiries to the business.
Classified posting is the main part of lead generation but apart from this you can add your business over several social media site by which many people will visit your site and this is also a part of effective lead generator.
I have heard that directory submissions does not create that much traffic to a website anymore.
Lead Generation can also be done within your blog, you can add up call-to-action stuff (like ads). Or share something through Social Media, more leads can be achieved through Social Media.
