Are web certifications, or any certification for that matter, worth it?

I am trying to figure out how to make myself more marketable to employers. I know I definitely need more experience, but I’ve had a hard time even getting companies to consider me so I can get more experience. I have a degree and a little experience, but that doesn’t seem to be enough. I am wondering if I could take an exam for some sort of certification to perhaps bolster my credentials. Would this be worth it?

I see that there are Adobe certifications, for example, and even ones for HTML and other coding languages. Would seeing such certifications on a person’s resume make them more desirable or do I need to just get another degree?
