Hi Sachin,
As long as you have API code or the press release was created in Marketo you should be able to.
Go to the analytics tab, and click on the report already generated by Marketo (Web Page Activity), Click smart list and add the filter either clicked link on webpage, or visited webpage depending on which you want. Then select either webpage is, contains, or starts with depending on which is best for your scnario. Since you do not want a date range click the X next to that field. Then you can click view qualified leads, then qualified leads and a list of leads will appear. You can change the view by clicking the view if it is not showing the information you want to see, and then you can export this data into excel, if you would like.
Hope that helps!
