What Tabbio's CV checker scores, and how to fix each part
Tabbio's CV checker gives your CV text an overall score out of 100. The score is built from five areas, and ATS compatibility and content carry the most weight. Alongside the score come three to six suggested edits, each with a priority, high first.
This guide covers what each area looks at and how to fix it. The checker reads your text, not your layout. That shapes every fix below.
The five areas and their weights
| Area | What it looks at |
|---|---|
| ATS compatibility | How cleanly a machine can read the text: clear structure, standard section headings, no tables, no images |
| Content & impact | Concrete impact, quantified outcomes, recent experience, and the scope and complexity of the work |
| Keywords | Skills and verbs that fit the role, judged against a target role if you choose one |
| Format & structure | Consistency, hierarchy, white space and reverse-chronological order |
| Readability | Sentence length, and plain, active language |
ATS compatibility and content together carry more than half of the overall score. Readability carries the least.
How to fix each area
ATS compatibility
ATS is short for applicant tracking system. This area asks how cleanly a machine can read your CV text. The rubric looks for clear structure and standard section headings, with no tables and no images. The checker only sees the text taken from your file, not the page itself. So read that extracted text first. If a table or a column came out jumbled, that's the version the checker scores.
Fix it: use plain section headings, such as Experience and Skills. Keep tables and images out of the file, and move what they held into ordinary lines of text.
Content & impact
This area looks for concrete impact and quantified outcomes. It also weighs how recent your experience is, and how big and complex the work was. A list of duties shows none of that.
Fix it: rewrite each bullet to say what changed because of your work. The checker's own example shows the shift. "Handled customer queries" describes a task. If your records support it, "Resolved 30 customer queries a day" adds useful context. Never add a number you can't back up, and give your most recent role the most detail.
Keywords
This area checks for skills and verbs that fit the role. Choose a target role and the checker compares your CV with the skills and tools listed for that role in Tabbio's role catalogue. You'll then see a fit score out of 100. Below it are two lists, matched skills and skills to add, with up to ten in each.
Fix it: name the skills and tools you actually use, by their usual names, and start bullets with a verb. Add something from the skills-to-add list only if you really have it.
Format & structure
This area looks at consistency, hierarchy, white space and order. The rubric expects reverse-chronological order, which puts your newest role first.
Fix it: move your latest job to the top and use one date format throughout. Give every section the same heading style, and leave space between sections.
Readability
This area looks at how long your sentences are and how plainly they're written, including whether they use the active voice.
Fix it: split long sentences in two. Start each line with what you did, so "Managed the team rota" rather than "Responsible for managing the team rota".
The four counts under the score
Below the five scores, the checker shows four counts.
- Words: the length of your CV text.
- Sections detected: how many separate heading blocks it found.
- Quantified wins: bullets that include a figure, such as a percentage or an amount of money.
- Reading time: your word count, read at 200 words a minute.
What the results show
The overall score comes first. Then "Improvements identified" lists three to six edits, sorted so the high-priority ones lead. "What's already working" names two to five strengths, and "Quick wins" lists up to six issues. If you chose a target role, a section headed "How well you match" adds the role fit.
Before you run a check
You can paste your CV text, or upload a supported document or text file of up to 10 MB. The text needs to be between 80 and 12,000 characters. If a scanned file gives no readable text, paste the text instead.
Your browser pulls the text out of the file. Running the check sends that text to Tabbio's analysis service, so remove contact details or anything else you'd rather not include.
What the score can't tell you
The score is an indicative review of your text. It isn't an employer's ATS result or a hiring guarantee. The checker can't reliably inspect your original layout, and it can't reproduce every employer's applicant tracking system. Each employer uses its own systems and criteria, so no score can guarantee acceptance.
An AI model applies the rubric to your text. Its instructions say to ground every point it makes in what your CV actually says. Treat the result as guidance, not a hiring decision.
Check your own CV
Paste your text into Tabbio's CV score checker and start with the high-priority edits, keeping every change true to your real experience. Then run it again and compare the five scores.
