    Copywriter and Online Marketing Specialist

    United States - Last active: 2 days ago - Tests: 10 - Portfolio: 12

    Too often, online marketers get caught up in chasing the next fad. But doing more business online is, at the heart of it, very similar to doing more business offline. Relationships are what's important, and hacks and tricks only go so far. I'm not your ordinary freelancer. I sometimes describe myself as "a writer who's not afraid of numbers." My drive to understand the written word and the world of business has given me an unusual collection of experiences and skills: -I'm an experienced copywriter who has created sales letters and other marketing materials for businesses several industries. -I'm a Google Partner, with certification in AdWords, Bing, and Google Analytics. I've successfully managed PPC programs with monthly spend ranging from under $1,000 to close to $45,000. I've also designed and run website split testing programs for clients. ***Please note that my rate for PPC is $50/hour.**** -In the past, I worked in publishing as a writer and editor for about 10 years, giving me a solid grounding in proper editorial procedures and standards, what materials sell, and the financial considerations involved in publishing a book. I've found that a lot of the business skills I've learned in this world are highly transferable to other industries. -I've been managing my own web-based businesses on the side since 2003. To any project, I bring a drive for thoroughness, patience, good judgment, and a deep investment in seeing my clients meet and exceed their goals. Your success is my success. I constantly test and look for data to support decisions. For my clients' ultimate benefit, I constantly seek out new learning opportunities (conferences, webinars, workshops, etc...). Finally, I'm highly dependable: I'm very selective about the commitments I make to insure that when I do take on a project I not only meet my responsibilities but hopefully knock it out of the park. I'm most interested in projects that allow me to work with a website's marketing needs in a holistic manner. Rather than push the particular solutions I can personally offer, such as AdWords or a content marketing campaign, I much prefer to analyze the needs of that particular business and come up with a plan that will address what's most needed, in the most effective way. If I don't think that a certain marketing technique will work well for you, I'll tell you so. I also work best with clients who understand that good results take time. I audit the work of others frequently, and have seen the consequences of going for the quick win without attention to long-term profitability. Sample Results (see also portfolio section below): -Created an extensive remarketing program with the highest ROI in an individual campaign at over 800%. For this client I have also been successful at cutting spend (in the case of one campaign as much as 88%) while maintaining sales. -Another client brought me on board to see if a display campaign set up by a previous consultant could be optimized further. When auditing the campaign I identified changes to the targeting that led to a 600% increase in leads. -I improved the click-through-rate (CTR) of an assisted living facility by 1700%, while halving the cost per click and raising the average position. -Through testing, I achieved ad-level CTRs as high as 12.28% (average 2.56%) for a WordPress developer. These results are for non-branded keywords. Client Comments (see also oDesk reviews): "Just took a look inside the account. You've really turned around the conversion rate. Thanks again for the great work on this." "I really appreciate your weekly reports, and how you provide a different perspective on the account's performance and what can be improved each time." "Your audit and keyword research has been extremely helpful to us in thinking about our business." [This client, a web developer, liked my analysis so much that they've hired me to provide the same service for their own clients.] "Thanks for the detailed report. This is a great start. Today we had 3 leads come in within 1h and 30m. That is highly unusual." I'd be delighted to discuss your online marketing program and what I can do to help.

    Software developer

    Norway - Last active: 3 days ago - Tests: 9 - Portfolio: 1

    I became fascinated with computers from an early age. At age 13 I started breaking down the software other people had made. I experimented and basically taught myself the mind of computers. I am autodidact in Basic, Turbo Pascal, Delphi. I am familiar with SQL. As for my computer-skills, I have myself developed some of the worlds fastest routines for managing vast amounts of data... I don't think I should go into the subject of all the software I have used and can use on a professional level (you would be stuck here reading for a very long time). I am in addition basically bilingual. Maybe this can be put to work for you. I really enjoy working with different languages.. Translating and transcribing is not only fun, I still come across a few words that I don't know, and that is the fun part of researching and learning.. I can translate these languages in a professional manner: English, Danish and Swedish ---> Norwegian Norwegian, Danish and Swedish ---> English Norwegian, English and Swedish ---> Danish For short texts, I also offer translation like: Norwegian, Danish and English ---> Swedish. German ---> Norwegian, Danish, English and Swedish. I can offer transcription of Norwegian, English and Swedish audiofiles. I would also love to do some German transcription for personal learning purposes.. My german understanding of the spoken language is not bad. (When the Danes start speaking properly, then I can do their language also :D, for now, it is too time-consuming for me.) Phew. That was a lot about language... Where did it all start you might wonder... Well.. It helps being told that you can not do it. (Don't listen to that you parents out there. Recognise your childrens values. Encourage them!) Apart from that, it does help to be stubborn! and travel around a bit is not bad either. Being a software developer is what I really want for my future. Challenges will come my way and I will do whatever I can to meet those challenges in a professional manner. Many old programmers or those taught a language at school see problems and a box they are stuck in. In school I was the one teaching my teachers. I was the one thinking outside the box to get things done. I can be stubborn some times, but in my mind, nothing is impossible. The impossible only takes a little bit longer time. I wish to put my skills into good use and I hope that will be something for you.
