Quick verdict: IELTS Liz is the better free resource - a complete, organised, zero-cost syllabus across all four skills. IELTS Advantage is the better investment when Writing blocks your band and you need expert correction of your own essays, not more lessons. Teaching versus feedback: that is the whole fork.
This pairing confuses candidates because both brands built their names the same way: years of consistently excellent free IELTS lessons. Search any Writing question and both will rank on page one.
But they have evolved into different businesses. IELTS Liz remains, at heart, a free teaching site with modest paid extras. IELTS Advantage is now a course company with a superb free blog as its front door. That difference decides most of the criteria below.
| Criterion | IELTS Liz | IELTS Advantage |
|---|---|---|
| Core identity | Free teaching site + small paid extras | Course business + strong free blog |
| Coverage | All four skills, organised by section | Writing-led, full-test coverage |
| Free content depth | Exceptional across the whole test | Exceptional, deepest on Writing |
| Personal feedback | None | One-on-one sessions in paid courses |
| Paid offer (as of 2026) | Advanced Task 2 lessons, modest price | Flagship VIP course ~$397 |
| Speaking help | Extensive free question banks + models | Course guidance and strategies |
| Practice scoring | None | None (feedback is human, in-course) |
| Best for | Free self-study across all skills | Paid Writing improvement with correction |
What each brand actually is
IELTS Liz (ieltsliz.com) is an experienced IELTS teacher's free library: tips, video lessons, model answers, practice exercises and current-year topic lists for every section of the test, still actively updated in 2026. Her paid catalogue stays deliberately small - advanced Writing Task 2 video lessons and e-books at a modest price.
IELTS Advantage (ieltsadvantage.com) publishes one of the most-read free IELTS blogs anywhere, and sells structured courses on top - the flagship VIP program (around $397 as of 2026) built around expert one-on-one feedback on your essays, with band-based guarantee terms.
Free teacher versus course company. Both excellent. Different purchases.
Content quality: a tie, split by skill
Across the whole test, the Liz site is the better-organised syllabus: every section has a hub, navigation is clean, and topic lists are refreshed annually. As a single free resource for all four skills, it has few equals.
On Writing specifically, IELTS Advantage publishes the deeper free analysis - long-form breakdowns of question types, structures and band descriptors that read like course excerpts, because that is effectively what they are.
Winner: tie - Liz for breadth and organisation, IELTS Advantage for Writing depth. You will likely end up reading both; most serious candidates do.
Writing help: IELTS Advantage
Here the business models separate. Liz teaches Writing superbly - structures, model answers, her advanced paid lessons go further still - but nobody at ieltsliz.com reads your essay.
The paid IELTS Advantage courses are organised around exactly that: expert eyes on your actual writing, one-on-one feedback sessions, corrections that compound over a course. For a candidate stuck at Writing 6.0 who has already consumed every free lesson, feedback - not more teaching - is usually the unlock.
Model answers show the destination; only feedback shows your distance from it. Our guide to the Band 7 essay structure pairs well with either brand's teaching. Winner: IELTS Advantage - it sells the thing free sites structurally cannot give.
Reading and Listening: IELTS Liz
Liz maintains dedicated, systematic Reading and Listening sections - strategy per question type, common mistakes, practice exercises - that make a complete free preparation possible for these skills.
IELTS Advantage covers both skills competently in its blog and courses, but they orbit the Writing core; the free material is thinner here than on essays.
Winner: IELTS Liz. Neither offers scored practice at volume for these skills - reading about Reading only goes so far, and both sites would tell you the same.
Speaking help: IELTS Liz
The Liz Speaking hub - Part 1, 2 and 3 question banks, model answers, fluency and pronunciation tips, current topic lists - is among the most useful free Speaking resources on the internet, full stop.
IELTS Advantage teaches Speaking strategy well within its courses and blog, but with less free volume and no live practice element in the standard offer.
Winner: IELTS Liz.
Pricing: IELTS Liz
Almost everything from Liz is free; her paid advanced lessons are a modest one-off (periodically discounted as of 2026), priced like a book rather than a course. Risk is near zero because the free pages already demonstrate the teaching.
IELTS Advantage's flagship runs around $397 as of 2026 - real money, but buying a different category of product: structured courses plus human correction and guarantee terms. Its free blog keeps the entry cost of the teaching itself at zero.
Winner: IELTS Liz on price, by an order of magnitude - with the caveat that she does not sell what IELTS Advantage sells. If you need correction, the cheaper product cannot substitute.
Progress tracking: neither
Both are teaching brands: no practice scoring, no wrong-answer analytics, no band trend. IELTS Advantage's paid courses add human checkpoints - your feedback sessions are, in effect, manual progress measurements - but nothing continuous or per-question-type.
For self-studiers on either brand, progress stays invisible between practice tests unless something else measures it.
Winner: neither - which is the opening for the third option below.
So which should you choose?
Start with Liz, whatever happens next: her free syllabus is the best-organised zero-cost preparation across all four skills, and for many candidates it is genuinely sufficient teaching.
Upgrade to IELTS Advantage when a specific condition is met: Writing blocks your target, you have exhausted free teaching, and what you need is expert correction of your own essays. That is the product, and for that candidate it earns its price.

What neither brand gives you - by design - is measured practice. Reading lessons without scored repetitions is theory without a lab.
The free-first upgrade path, step by step
Step one: baseline. Before consuming either brand, take a full timed practice test and record your band per skill. Free lessons are most valuable when they are aimed at a known gap rather than browsed for reassurance.
Step two: four weeks on the free layer. The Liz syllabus for your weak skills, the free IELTS Advantage Writing articles for every essay you draft, and timed practice between lessons. Most candidates gain half a band or more from this stage alone, at zero cost.
Step three: retest and diagnose. If your bands moved, stay free - repeat the cycle. If everything moved except Writing, you have found the classic case for paid correction: your grammar and structure knowledge is in, but nobody has told you what your essays specifically do wrong.
Step four: buy the narrowest fix. That usually means the corrected course for Writing, not a general subscription for everything - you already own the general layer free. Set a review date six weeks after purchase and judge the spend against the band, not against how the course feels.
This order matters because it spends money last, on the smallest possible target, with evidence. The reverse order - buy first, diagnose later - is how candidates end up owning three courses and the same band they started with.
The third option most people actually pick: IELTSbiz
Full disclosure before this section: IELTSbiz is our own platform, so weigh that as you read. Both brands above deserve their reputations; the case here is that both leave the same gap open.
IELTSbiz is the lab to their theory.
The practice engine generates unlimited fresh Cambridge-style passages across all 11 Reading question types and explains every wrong answer at the trap level - naming the specific distractor pattern that caught you - so each of the strategies you learned from Liz gets tested against scored repetitions the same day.
Per-question-type band tracking turns your preparation into a visible trend, and the AI Writing Checker supplies unlimited essay feedback against all four official criteria between - or instead of - human corrections. The accuracy is published: IELTSbiz's study of 1,200 essays found AI band scores matched human examiners within ±0.5 bands in 94.2% of cases.
It is free to start with no card, then $6.99/month or $29 lifetime - see pricing - closer to the Liz price bracket than the course bracket. The honest limits: no human feedback sessions, no live teaching, and its lessons are feedback-shaped rather than a video syllabus.
The natural stack: the free Liz syllabus for teaching, IELTSbiz for scored practice and band tracking, and IELTS Advantage's corrected courses as the targeted upgrade if Writing alone still refuses to move.
| Criterion | IELTS Liz | IELTS Advantage | IELTSbiz |
|---|---|---|---|
| Core strength | Free all-skills syllabus | Corrected Writing courses | Measured practice + band tracking |
| Practice supply | Exercises, not scored | Course-tied sets | Unlimited generated passages |
| Wrong-answer feedback | None | Human, in paid courses | Trap-level feedback on every miss |
| Writing checks | Model answers only | One-on-one expert sessions | Unlimited AI checks, four criteria |
| Band tracking | None | Human checkpoints | Per-question-type band over time |
| Price (as of 2026) | Free + modest paid lessons | ~$397 flagship one-off | Free start; $6.99/mo or $29 lifetime |
Learn free, measure cheap, buy correction only for the skill that will not move. That order gets most candidates to their band for the least money.
