Secret Tips to Optimize Your Upwork Profile to Get Noticed and Get Invites Without Reviews

Introduction

Unlock secret tips to optimize your Upwork profile, rank higher, and get client invites without reviews. Learn keyword, title, and skill strategies that work in 2025.

If you’ve ever asked yourself, “How do I start getting invites on Upwork when I don’t have reviews yet?”, then this guide is for you.

Many new freelancers believe reviews are what get them discovered. But here’s the truth: Upwork ranks activity, not just reviews. The platform rewards optimized profiles, relevant keywords, and consistent engagement.

Let’s dive into the real strategy that helps new and seasoned freelancers rank high, get noticed, and receive DMs,  even with zero reviews.

Why Waiting for Reviews is a Mistake

As shared in the training by Okuwa Ayomide M, waiting for reviews is like waiting for permission to succeed.

Most freelancers think their first job is the key to visibility. In reality, it’s the opposite,  visibility brings your first job.

Upwork’s algorithm is built to connect active, optimized profiles with client searches. Every keyword, title, skill tag, and portfolio you add increases your chances of being discovered.

Action creates results, not waiting.

Step 1: Keyword Search & Research (Day 1)

Before rewriting your profile, analyze what clients are actually searching for.

In our research across dozens of job posts in web design category, the most common client keywords were:

  • WordPress, Elementor, GoHighLevel (GHL)

  • Bubble.io, Softr, Webflow, Adalo

  • Landing Page Design, SEO Optimization, UX/UI Design

  • Automation, Funnel Building, CRM Workflows

  • Responsive Design, Conversion Optimization

These are the exact words clients type into Upwork’s search bar when looking for freelancers to invite.

Pro Tip: Search jobs in your niche, read 10–20 postings, and note recurring skills, tools, and phrases. Those are your SEO triggers.

How to do this? follow the steps in the training section below

Step 2: Profile Description Optimization

Combine your experience with the client keywords you discovered.
Here’s a snippet from a top-performing profile summary structure we built:

“Transform your business vision into a high-performing online presence — with an expert web designer and developer specializing in WordPress, GoHighLevel (GHL), Bubble.io, and modern CMS solutions. I design conversion-focused, responsive, and SEO-optimized websites that help businesses grow…”

This approach naturally ranks your profile when clients search for WordPress expert, GHL funnel builder, or Bubble.io developer.

Keep it clear, human, and confident. Avoid AI fluff.

Step 3: Profile Title Optimization

Your title is Upwork SEO gold. It must be short, keyword-rich, and client-focused.

Example of an optimized title:

WordPress, GoHighLevel & Bubble.io Web Designer | Landing Page Expert

Why it works:

  • It includes the top-ranking client keywords.

  • It reads naturally and highlights specialization.

  • It fits within Upwork’s 70-character limit.

Keep it clear, human, and confident. Avoid AI fluff.

BELOW ARE PROMPTS TO USE WITH AI, WATCH THE VIDEO TO UNDERSTAND HOW AND WHERE TO USE THEM!

Prompt 1 – Profile description
I want to optimize my upwork profile so that i rank high in the search results for whenever clients are looking for freelancers to invite to their projects. i will give you a list of job posts, then i want you to analyse said job posts and identify the most reccuring keywords, phrases, and requirements that these clients have. once you’re done with that, i will then give you my current profile that contains summary of my experience, combine my profile with the results of your analysis to create a master profile description that contains all the recurring keywords so that my profile is optimised for client job post. retain my writing style and general structure, but infuse as many of these keywords and phrases that clients are using to describe their job posts so my profile captures their searches.

Prompt 2 – Profile Title
hi chat.. now i want to optimize my profile title to capture the titles that clients are using for their job posts i will give you a list of current job post titles and i want you to create a master profile title that captures as many of the recurring keywords as possible but limited to 70 characters. here are the job titles;

Prompt 3 – Skills
And finally, i will give you a list of skills that clients are using to tag their job posts. Analyse the list i will give you and tell me the most recurring from the most frequent to the least frequent. tell me the number of times each appears Here are the skills;

Prompt 4 – Skills
use these top recurring skills clients value most to craft an optimized 15 skills

Step 4: Build Depth with Employment, Experience, and Portfolios

Add more than 90 employment histories, experiences, and portfolios using the exact keywords gathered, repeated in a structured pattern.

This isn’t keyword stuffing; it’s strategic repetition.

Each entry reinforces your expertise across multiple searches. For example:

  • WordPress Landing Page Designer for a Marketing Agency

  • GoHighLevel Funnel Optimization Project for SaaS Brand

  • Bubble.io Web App Prototype for E-learning Platform

The goal: show Upwork’s algorithm that your profile consistently aligns with client demand.

Step 5: Add Service Catalogs

Add 10-12 Upwork Project Catalogs using your main keywords (e.g., “Design a High-Converting WordPress Landing Page” or “Build an Automated GoHighLevel Funnel”).

Catalogs improve your visibility in Upwork’s “Buy Now” section, a feature where clients can instantly purchase your service without posting a job.

Step 6: Stay Active, Upwork Ranks Activity

Profile optimization is half the job. The other half is staying active:

  • Apply for 3-5 relevant jobs daily.

  • Update your portfolio weekly.

  • Refresh your overview every month.

  • Log in consistently,  even if you don’t submit proposals.

Active profiles appear higher in client searches, especially when your keywords match theirs.

Final Thoughts: Action Builds Authority

Getting invites without reviews isn’t luck, it’s strategy plus consistency.

When you optimize your Upwork profile using the right keywords, skills, and titles, and stay active on the platform, you make it easy for clients to find you.

Remember:

“Reviews come after visibility, visibility comes from optimization.”

Stop waiting for your first review. Start positioning yourself like the professional clients are already searching for.
