How to add your startup to Top Similar Sites
TL;DR
Top Similar Sites (topsimilarsites.com) is a free directory of website alternatives that has run since 2012. Anyone can suggest a site through a free form, editors review suggestions before they go live, and an approved startup gets its own page and appears in the "similar sites" lists of its competitors. Outbound links carry nofollow, so the gain is visibility among people comparing tools, plus a free competitor map.
What is Top Similar Sites?
Type a domain and Top Similar Sites returns the sites that do the same thing, each with a match score from 1 to 99%. Its About page explains the method:
- the index starts from the most linked websites on the web, the Majestic Million, and adds sites that visitors suggest;
- a language model reads how each homepage describes itself and matches sites that offer the same thing, in any language;
- visitor votes move matches up or down, and editors review visitor suggestions before they go live;
- a crawler, TopSimilarSitesBot/2.0, checks every listed homepage about once a month, and sites that shut down, are parked or are for sale drop out.
Each site page (topsimilarsites.com/similar-to/yourdomain.com) shows a short description, the site's language, its closest alternatives and a "which is better" comparison. The directory runs in 12 languages and adds sites every day: on 30 October 2026 its "Recently added" list showed entries from one day earlier. It also offers free website checks such as a tech detector and a DNS lookup.
Who should submit to Top Similar Sites?
- SaaS and consumer web startups with clear, named competitors: your page lists them, and their pages can list you.
- Founders who want to be found by people looking for "sites like" or "alternatives to" a bigger brand.
- Anyone who needs a quick competitor list before a pitch; the search works without submitting anything.
- Skip it if you want a backlink for SEO, because the "Visit" buttons are nofollow. Adult sites are not listed at all.
How much does Top Similar Sites cost?
Suggesting a site is free. An Advertise page exists with a contact form, but it publishes no prices, and we found no paid listing or paid fast track.
How do you add your startup to Top Similar Sites?
- Search your own domain on topsimilarsites.com first. Sites from the Majestic Million and earlier suggestions are already in the index.
- If your startup is missing, open the Suggest site form.
- Fill in the website field and a message. Name, email and subject are optional; add your email if you want a reply.
- In the message, state your category and the two or three well-known sites your product resembles.
- Wait for an editor to review the suggestion. Top Similar Sites publishes no review time.
Tips to get more out of Top Similar Sites
- Rewrite your homepage title and first paragraph in plain words before you submit. The matching model reads how your homepage describes itself, and a vague hero line puts you next to the wrong sites.
- Name the competitors you want to sit next to. The site combines hand-picked suggestions from visitors and editors about which sites belong together.
- Vote on the matches on your own page and report wrong ones, since strong negative votes remove a suggestion and positive votes add new matches.
