The objective should be not to create a simple keyword rich landing page for the engines but to create one which will get top ranked and which will lead to better “conversion” for the client. All landing pages should have one or all of the call to action elements on it:

1. Incentive/ discount information to catch the attention/ “attract eye balls”.

2. Phone# to get the direct calls

3. Form/ email ID to collect the leads

4. Information about the past work done to enthuse confidence in the visitor to contact

5.Client testimonials again to enthuse confidence in the visitor to contact
