• Reed.com is an excellent site with very user friendly interfaces including a record of your job application history. So it is a simple task to revisit the job description when the employer contacts you weeks after you had first applied for the job. Be prepared to visit this site on a daily basis since only a maximum of twenty pages are allowed for a job search – too few for a high volume sector like IT.
  
• Monster.co.uk remains a very U.S.A centric jobsite. Few U.K based companies would use this site as their exclusive recruiting resource. Nevertheless this is an important resource in so far as American companies due to familiarity with Monster are likely to use the site for their U.K based positions as well. One difficulty with using Monster.com is the repetition of the same jobs every day, making it difficult to identify the fresh ones.
  
• Guardian.com is excellent for public and charity sector jobs. The site leverages the strong readership which the Guardian newspaper enjoys with the bourgeois professional class in the U.K.
  
• Jobsite.com has excellent search features including the functionality to NOT show jobs meeting specific criteria. This comes in handy for instance when you are searching for ‘research’ jobs but are not interested in SAS ( a database software).
  
• Jobserve.com is one of the pioneers in the job search industry and offers a comprehensive selection of jobs particularly in the technology sector.
  
• Totaljobs.com has a good selection of jobs although like in Monster.com, it isn’t easy to spot the fresh jobs of the day.
  
• Jobcentreplus.com is a government network of employment support centers. Use this site in conjunction with enrolment at your local Job Centre.

Beyond the big job boards there are several other job boards that just source some great jobs owing to their specific connections and specializations. Sites like Times.com and Telegraph.com exploit their newspaper heritage but lack a user friendly interface. Fish4jobs has a good selection of jobs in the lower salary range.

Metasites claim to be a one-stop shop enabling you to search several job sites all at once. However it is anybody’s guess as to how comprehensive they are besides not being the ‘real thing’ in job search.

Large recruitment agencies (some are large enough to be Fortune 500 companies) have a wide selection of jobs on their proprietary jobsites. These jobs are usually exclusive to the agencies and only a few of them are also advertised on the big job sites. Several leading companies recruit solely through the large agencies. It therefore definitely pays to visit these jobsites to pick up some truly excellent jobs.

Top jobsites in the USA like hotjobs.com and careerbuilder.com have a good number of UK jobs; usually American companies like GE advertising their UK based jobs.

Sector specific sites are useful supplements to the big job sites. These sites source some great jobs through their focus and relationships although lacking in the user-friendly interfaces and brand recognition of the big job sites. For instance CW Jobs.com hosts hundreds of IT jobs but is weak in search functionality making it difficult to zero in on jobs with specific skills. Sector specific sites also offer a wealth of advice and career resources. Niche sectors such as sports jobs and legal jobs are better covered by sector specific job sites. Graduate (non-experienced) jobs too are fewer in the big job sites and you might find more jobs for freshers on specialized sites.

Job sites specializing in local jobs are weak in the UK but could prove useful for office support jobs in distinct areas like Cornwall or Scotland.
