The template of the resume which is actually the outline or the structure of the resume decides the positioning of every element of the resume. If this positioning is clear and clean with an equal weightage given to every element it appears that there is a flow in the format and so the resume appears attractive. Such a resume neither looks like a piece of art which shows that you were keen about the outline of the resume rather than the content nor does it appear as an essay.
There are millions of resumes being uploaded to job sites and because of this job sites have an ongoing need for more and more web servers. Job sites earn revenue from recruiters and employers that are subscribers and not from job seekers so it makes sense to eliminate this cost and pass it on to the resume website provider. Since people manage multiple resumes in their profiles to apply for different jobs it would be better for everyone if job seekers had multiple links to different resume pages instead of resume PDFs. The storage cost to job sites is eliminated and job sites can reduce their fees to subscribers.
Ask yourself - is a cheap resume of any worth if all it does is extending the period of your job search? The answer is simple - no. The cost should not be the sole focus when you choose a resume writing service. The priority should be on the quality of the final product. Only a unique resume that captures the attention of prospective employers and guarantees an interview call is worth your money.
