It will be difficult to explain the gap between your studies and job trials. If you have not worked at all, then it is going to be real tough to convince that you are a Candidate who the Company can hire. From the time you complete your studies, the first 12 month period is a Fresher period and that is when the companies look out for Freshers. There are Candidates who get placed even after a year or so if they have done a certification course or have utilised the gap period doing any internship or a certification course. But if there is no work experience of whatsoever sort, it might be difficult to explain the reason behind the gap. And certifications do add value but if there is no relevant work experience where you put your certification knowledge to use, it might not serve purpose. So this is something that you have to think about. May be start ups will be willing to hire you but the salary might be less.
