Key Elements of a Strong Cover Letter
Start with your name, phone, email, and a link to your LinkedIn or portfolio site if you have one. Include the date and the employer's contact details to show you tailored the letter for this role.
Begin with a short sentence that explains why you are excited about the role and the company. Mention a relevant project, internship, or coursework to show early credibility.
Highlight 2 to 3 skills that match the job posting, such as Google Ads, keyword research, or campaign analysis. Whenever possible, add measurable outcomes from class projects, internships, or personal campaigns to show real results.
End by reinforcing your interest and asking for a next step, like a meeting or interview. Thank the reader for their time and note that your resume and portfolio links are attached.
Cover Letter Structure
1. Header
Place your name and contact lines at the top, followed by the date and the employer's contact information. Keep the header concise and professional so the reader can contact you easily.
2. Greeting
Address the hiring manager by name when you can, and use a neutral option like 'Dear Hiring Manager' if you cannot find a name. A personalized greeting shows you did a little research and care about the role.
3. Opening Paragraph
Write a one to two sentence opening that states the position you are applying for and why you are interested in that company. Include one quick detail that links your background to the role, such as an internship, relevant coursework, or a small campaign you ran.
4. Body Paragraph(s)
Use one or two short paragraphs to describe relevant skills, tools, and accomplishments that match the job description. Focus on concrete examples like improving click-through rates, running keyword tests, or analyzing campaign data, and include metrics when you have them.
5. Closing Paragraph
Finish with a brief paragraph that reiterates your enthusiasm and suggests a next step, such as a conversation or interview. Thank the reader for considering your application and mention that your resume and links are attached.
6. Signature
Use a professional sign-off such as 'Sincerely' or 'Best regards' followed by your full name. Under your name, include a link to your portfolio or LinkedIn if you did not place it in the header.
Dos and Don'ts
Do match keywords and skills from the job posting, focusing on the most relevant tools and tasks. This helps the reader see you are a good fit without repeating your entire resume.
Do quantify any results from projects or internships, even small wins like a 10% improvement in impressions. Numbers show impact and make your examples more believable.
Do keep your letter to one page and use short paragraphs for readability. A concise, well-structured letter is easier to scan and more likely to be read entirely.
Do show a learning mindset by noting courses, certifications, or small experiments you ran. Employers hiring entry-level candidates want to see curiosity and the ability to grow.
Do proofread for typos and clarity, and ask a friend or mentor to review your letter before sending it. Fresh eyes often catch awkward phrasing or missing details.
Don't copy your resume line for line into the cover letter, but do reference a few key accomplishments. The letter should complement the resume with context and motivation.
Don't claim experience you do not have or exaggerate results, as this can hurt your credibility in interviews. Honesty builds trust and lets you explain growth areas during a conversation.
Don't use vague buzzwords without examples, such as saying you 'improved performance' without showing how. Concrete actions and outcomes are more persuasive than empty phrases.
Don't write long dense paragraphs that are hard to scan, and avoid including irrelevant hobbies. Keep every sentence focused on the role and your fit for it.
Don't forget to customize each letter for the company and role, even if you reuse a template. Small details that match the job or company culture make a big difference.
Common Mistakes to Avoid
Not tailoring the letter to the specific role makes it feel generic and reduces impact. Always reference one or two role-specific responsibilities or company initiatives.
Starting with a weak opening like 'I am writing to apply' misses an opportunity to engage the reader. Lead with a brief reason you are excited or a standout result.
Listing tools without context leaves the reader wondering how you used them, so add short examples. Mention a tool and pair it with a task or outcome to show competence.
Forgetting to include contact information or links means interested hiring managers may not know how to follow up. Double-check that links work and contact lines are current.
Practical Writing Tips & Customization Guide
Include a short link to a one-page portfolio or campaign summary that showcases your best work. A quick sample gives hiring managers more confidence in your practical skills.
Reference a brief result from a class project or volunteer campaign to demonstrate applied skills, such as lowering cost-per-click in a test campaign. Even classroom work can show your approach to SEM problems.
Mention specific tools you know like Google Ads, Google Analytics, or keyword research platforms, and pair each with a sentence about how you used them. This shows both knowledge and hands-on experience.
Keep a master template for structure but rewrite the opening and one example for each application to keep the letter personal. Small tweaks save time while keeping your application tailored.
Cover Letter Examples
Example 1 — Recent Graduate (Data-focused)
Dear Hiring Manager,
I recently completed a B. S.
in Marketing and a 6-month paid internship managing Google Ads for a local retailer with a $6,000 monthly budget. During that internship I implemented search-term pruning and ad-schedule adjustments that raised click-through rate by 18% and lowered cost per acquisition by 14% within three months.
I hold the Google Ads Search and Google Analytics certifications and built automated reporting in Sheets that saved my team 6 hours weekly.
I’m excited by your focus on performance-driven growth and would bring disciplined testing: one hypothesis per campaign, clear KPIs, and weekly data reviews. I’m comfortable with keyword research, bid strategies, and basic HTML for landing page tweaks.
I’d welcome the chance to run a 30-day test to improve CTR or reduce CPA on one priority campaign.
Thank you for considering my application. I look forward to showing how measurable wins at scale can start in this role.
Sincerely, Alex Chen

- •Shows specific metrics (18% CTR increase, 14% CPA reduction) and budget size ($6,000/month).

Example 2 — Career Changer (Transferable Skills)
Dear Hiring Manager,
After three years as a marketing coordinator managing email and paid social campaigns, I’m shifting into search because I enjoy data-driven optimization. In my last role I ran A/B tests across 120 email segments and boosted revenue per recipient by 22% while managing a $5,000 monthly ad test budget.
I translated audience insights into creatives and bids, skills that map directly to keyword segmentation and ad copy testing.
Over the past six months I completed a hands-on SEM bootcamp where I planned keyword structures, set up shopping campaigns, and practiced bid simulators. I’ve reduced CPA in tests by 28% on small budgets and I’m familiar with Google Ads, Microsoft Advertising, and Excel pivot-analysis.
I’m ready to apply that experimental mindset to paid search, starting with auditing low-performing campaigns and prioritizing high-impact tests.
I’d appreciate 20 minutes to discuss how my optimization process and analytics background can help reach your acquisition targets.
Best regards, Maya Patel

Example 3 — Experienced Professional Pivoting to SEM
Dear Hiring Manager,
With four years managing digital campaigns across search, social, and display, I’m applying for the entry-level SEM Specialist role to focus on paid search execution. In my most recent role I oversaw a $50,000 monthly media budget, improved account-level conversion rate from 3.
2% to 3. 9% in six months, and introduced routine attribution checks that corrected underreported search conversions by 12%.
I bring hands-on experience in bid rules, structured naming conventions, and cross-channel tagging—skills that reduce wasted spend and accelerate learning. I’m proficient in Google Ads, Microsoft Advertising, Data Studio, and basic SQL for joining performance tables.
I enjoy documenting playbooks; my last playbook reduced campaign setup time by 40%.
I’d like to leverage that operational experience to scale your paid search program while learning tactical SEM techniques from your team.
Thank you for your time, Jorge Alvarez
