Writing a blog is not going to help students who want to earn extra money by working from home if companies willing to provide that money aren't able to contact the blog author. A good strategy for students and graduates who want to make money from their blog is to have a media / contact / advertising page on their blog and to make sure this is clearly visible so people can spot it easily.

An advertising page should contain an email address or contact form, maybe a summary of fees and also information provided by the blogger about what they are looking for from potential advertisers and what they can offer the advertiser in return. Student bloggers can also create media packs that can be requested by businesses. This might contain an organised list of fees, advertisement timescales, blog page rank, most-visited posts and screenshots of Google analytics figures. This is worth spending time on in the beginning because it will make life much easier for busy students to send this to advertisers rather than having to type everything out in an email each time they receive a request.

A media pack should be updated every few weeks to keep statistics and figures contemporary.
