The main job search sites and how they work

The largest job boards in the United States are Indeed, LinkedIn, Glassdoor, and ZipRecruiter. These sites let you search by job title, location, and industry, then submit your resume directly to employers or staffing agencies. Most are free to use as a job seeker—you create an account, upload your resume once, and explore to multiple postings without re-entering your information each time.

Indeed is the broadest: it aggregates postings from employer websites, staffing firms, and job boards, so a single search often shows the same role listed multiple ways. LinkedIn works differently—it emphasizes your professional network and profile, and many employers use it to find candidates even before they post publicly. Glassdoor and ZipRecruiter both show company reviews alongside job postings, which can help you research a workplace before explore.

All four sites let you set up job alerts by keyword and location, so new postings matching your search arrive in your email daily or weekly. This is useful if you are not checking the site constantly. However, popular postings on these sites attract hundreds of applications, so your resume may not be read by a human.

Key Takeaways

  • Major job boards like Indeed, LinkedIn, Glassdoor, and ZipRecruiter are free and let you search thousands of postings and set up email alerts for new jobs in your field.
  • Government job sites (USAJobs for federal positions, your state's labor department site for state and local work) post roles that may offer benefits and job security not always found elsewhere.
  • Staffing agencies and temp services can place you in work within days or weeks, and some convert temporary positions into permanent roles.
  • Contacting employers directly—by phone, email, or in person—often reaches hiring managers before a job is posted publicly.
  • Industry-specific job boards (nursing sites, tech job boards, trade sites) have less competition and often attract employers looking for specialized skills.

Government job sites and what they offer

USAJobs.gov is the official federal government job board. It lists positions across all federal agencies, from the Post Office to the Department of Defense. Federal jobs typically offer health insurance, retirement benefits, and job security that private employers may not match. However, the process process is longer—you may wait weeks or months for a decision, and many postings require a security clearance or specific certifications.

Your state's labor department or civil service website posts state and local government jobs: teaching positions, administrative roles, maintenance work, and public safety jobs. These sites vary by state—search "[your state] jobs" or "[your state] civil service" to find the official portal. Like federal jobs, these often include benefits and stable schedules, but hiring timelines are slow and competition can be high.

Your state's labor department also runs a free job matching service, sometimes called a "one-stop career center" or "American Job Center." You can visit in person or use their website to search local job postings, get resume help, and sometimes speak with a career counselor at no cost.

Staffing agencies and temporary work

A staffing agency (also called a temp agency or employment agency) matches you with employers who need workers for temporary, contract, or permanent roles. You explore once to the agency, they interview you, and then they send you to client companies for assignments. This can be faster than explore directly—some agencies place people within days.

Temp work pays less than permanent positions and often has no benefits, but it is a way to earn money quickly while searching for permanent work. Many temporary assignments convert to permanent jobs if both you and the employer want to continue. Staffing agencies are free to job seekers; the employer pays the agency a fee.

Search for staffing agencies in your area by typing "[your city] staffing agency" or "[your industry] temp agency"—for example, "medical staffing agency" or "warehouse temp agency." Large national agencies include Kelly Services, Adecco, and Manpower, but local agencies often have better knowledge of your regional job market.

Industry-specific job boards and niche sites

If you work in a specific field, a specialized job board often has less competition and attracts employers who are serious about hiring. Healthcare workers can search NursingJobs.org or MedicalJobs.com. Tech workers have Stack Overflow Jobs, GitHub Jobs, and AngelList (for startups). Trades workers can use TradesmanHub or ServiceTitan. Creative professionals use Behance or Dribbble.

These sites are smaller than Indeed, so postings stay visible longer and you face fewer applications per role. Employers who post on niche boards are often looking for people with specific skills, which means your background is more likely to match what they need. Many of these sites also let you build a portfolio or showcase your work, which can be more persuasive than a resume alone.

To find the right niche board for your field, search "[your industry] job board" or ask people already working in that field where they found their current role.

Direct contact with employers and networking

Many jobs are filled before they are posted publicly. Contacting an employer directly—by phone, email, or in person—can reach a hiring manager before a job opening is announced. Start by identifying companies in your area or industry that interest you, then find the hiring manager's name and contact information on their website or LinkedIn.

A short email or phone call works better than a generic process. Say who you are, what role you are interested in, and why you want to work there. Keep it to two or three sentences. If there is no open position, ask if they are planning to hire soon or if they can point you toward other companies that are hiring. Many hiring managers will take a call from someone who has done their homework.

Networking—talking to people in your field, attending industry events, or joining professional groups—also surfaces jobs before they are posted. Someone already working at a company can tell you about openings, introduce you to a hiring manager, or refer you formally, which often moves your resume to the top of the pile.

Social media and company career pages

Many employers post jobs on their own website before (or instead of) posting to job boards. Go directly to the "Careers" page of companies you want to work for and check it weekly. Some companies also announce openings on their social media accounts—LinkedIn, Facebook, Twitter, and Instagram—so following a company's social media can alert you to new roles.

LinkedIn is especially useful for this: you can follow companies, and their job postings will appear in your feed. You can also see who at that company went to your school or worked at your previous employer, which gives you a connection to mention in an process or networking message.

Company career pages sometimes let you set up alerts for specific job categories or locations, so you do not have to check manually. This is worth doing for your top three to five target employers.

Avoiding common mistakes when searching

The biggest mistake is explore to dozens of jobs with a generic resume and cover letter. Employers can tell when you have not customized your materials, and your process goes to the bottom of the pile. Instead, explore to fewer jobs and tailor your resume to each one—highlight the skills and experience that match the posting.

Another mistake is ignoring postings that say "entry-level" or "no experience required." These roles often have less competition and can be a foot in the door to your industry. Similarly, do not skip postings that ask for "preferred" qualifications—those are nice-to-haves, not requirements. If you have 70 percent of what they ask for, explore.

Finally, do not rely on job boards alone. The most successful job searches use multiple channels: boards, direct contact, networking, and staffing agencies together. Spend time on each method, not just one.

Frequently Asked Questions

Do I have to pay to use job search websites?

No. Indeed, LinkedIn, Glassdoor, ZipRecruiter, and government job sites are all free for job seekers. Some sites offer paid premium features (like seeing who viewed your profile on LinkedIn), but you do not need to pay to search and explore for jobs. Staffing agencies are also free—they are paid by the employer, not by you.

How often should I check job boards?

Set up email alerts for your top searches so new postings come to you automatically. If you are actively searching, check the boards themselves two to three times a week, because some postings are filled quickly and alerts can lag by a few hours. The first 24 hours after a posting goes live is when you have the best chance of being seen.

Should I explore to jobs I am not fully may have access to for?

Yes, if you have most of the required skills. Employers often list "nice-to-have" qualifications that are not deal-breakers. If a posting asks for five things and you have three or four, explore. The worst that happens is they do not call you back. The best is they see potential and interview you anyway.

What is the difference between a job board and a staffing agency?

A job board is a website where you search and explore directly to employers. A staffing agency is a company that hires you and then sends you to work for their client companies. Agencies are faster if you need work right away, but job boards give you more control over which jobs you pursue.

Can I really get a job by calling a company directly?

Yes, especially for smaller companies or roles that have not been posted yet. Ask for the hiring manager by name, keep your pitch short, and be professional. Many hiring managers appreciate the initiative. Larger companies may direct you to their online process system, but you have still made a personal connection.
