With an estimated 6.3 billion people, or 76% of the world's population, using the Internet in 2026 (ITU, Facts and Figures 2026), there's no doubt that you can find the right classified website for your needs. However, it’s important to find the most reliable classified websites for your niche market before you place your ads.
Part of the guide Classifieds sites by country
Why is choosing the most appropriate website crucial?
It’s simple: otherwise you’ll spend a lot of time and effort and gain little.
For example, if you choose to sell property on a reliable and high-traffic real estate website that focuses on renting homes, the chances of selling there are lower as people won’t be looking for your product. Instead, if you focus your energy on market research, and find the right websites, you’ll gain more with less.
There are different types of classified websites and the most popular ones, e.g. Craigslist or Locanto, are called 'general classified sites'. There is a lot to consider when posting your ads, for instance, the title and content of your classified ad, appropriate time of posting and more. You can read about those on our blog, but today we are going to talk about real estate classifieds.
Here’s a list of the best global real estate websites, according to statistics on Similarweb, descriptions of their services, and some handy information.
What has changed since 2020: the latest numbers and rules
The traffic figures in the profiles below date from 2020. Here are the latest figures the portals have published themselves:
| Portal | Latest official figure | Source |
| Zillow Group (Zillow, Trulia) | 239 million average monthly unique users and 2.5 billion visits in Q2 2026, both down 2% year on year; quarterly revenue up 18% to $772 million | Zillow Q2 2026 results, August 5, 2026 |
| Rightmove (UK) | 16.8 billion minutes spent on the platform in 2025; 89% of time spent on UK property portals in December 2025 by Comscore's measure (75% by Similarweb/data.ai/Sensor Tower); 16,385 estate agency branches advertising; revenue of £425.1 million | Rightmove FY2025 results, February 27, 2026 |
| ImmoScout24 (Germany) | About 19 million users a month on the website and app; Scout24 revenue of €649.6 million in 2025 (+14.7%) | Scout24, February 26, 2026 |
| Idealista (Spain, Italy, Portugal) | Cinven bought a 70% stake in June 2024, valuing Idealista at €2.9 billion | Iberian Property |
Two things stand out. Rightmove's lead in the UK has grown: its Comscore share of time rose from 83% in December 2024 to 89% in December 2025, and stayed above 80% for the whole of 2025. Zillow's revenue grew 18% in Q2 2026 even though its traffic dipped, so the money is now coming from earning more per visitor rather than from more visitors.
New rules for US listings
If you are listing property in the US, two changes since this article was written affect how your ad is shown:
- NAR settlement (from August 17, 2024): offers of compensation to buyer agents can no longer be published on the MLS, and agents working with a buyer need a written agreement before touring a home (NAR settlement FAQs).
- Zillow Listing Access Standards (blocking from June 30, 2025): a home that an agent markets publicly has to be entered into the MLS within one business day. From an agent's third non-compliant listing onwards, those listings are kept off Zillow and Trulia. For-sale-by-owner homes, new construction and rentals are exempt (RISMedia, May 20, 2025).
How to use this list
Pick the portal that leads in your country rather than the biggest one worldwide: Zillow for the US, Rightmove for the UK, ImmoScout24 for Germany, Idealista for Spain, Italy and Portugal. If you work through an agent in the US, ask how the listing will reach the MLS so it isn't blocked from Zillow. Check each portal's current audience figures yourself before paying for premium placement.
