Why should I optimize my OpenSea collection?

Optimizing your collection on OpenSea by adding all the relevant information, links, and images helps people discover your work. Some areas of OpenSea's homepage are curated by our team, who look for great collections to feature. By optimizing your collection page with all the relevant information, links, and images, we are better able to learn about your project. This doesn't guarantee a feature on our platforms since many factors go into our curation, but it does help our team evaluate your collection.

Additionally, as the largest NFT marketplace, OpenSea is the destination for many NFT collectors looking for new projects to participate in. Making the most of your collection page helps them better understand your project.

What do I need to create a new NFT collection?

To create an NFT on OpenSea, you’ll need a few things: an OpenSea account, a crypto wallet, and something really awesome to sell. It’s up to you to decide what that awesome thing will be. 

Next, choose a blockchain on which to mint your NFT.  “Minting” an NFT is the process of writing a digital item to the blockchain. This establishes its immutable record of authenticity and ownership. 

If you’re creating a collection for the first time, you will have the option to choose the blockchain you want it to exist on, but once this is chosen and saved, you won’t be able to change it. With that in mind, depending on the blockchain you’ve chosen, you may still be able to change the payment token that can be used to buy and sell your NFTs.

Then, you can create your collection. Decide what your collection of NFTs is all about. Is it artwork, a collection of profile pictures, sports memorabilia, membership to a group, or something else entirely? Once you decide, it’s time to fill in all the details.

OpenSea makes it simple and fast to create an NFT.

First, you’ll need to create a collection.

How do I update the information on my existing OpenSea collection?

First, navigate to “My Collections” on OpenSea’s website by hovering over your profile picture. Select an existing collection. From there, click on the three dots in the top right corner of the page and select “Edit” from the dropdown menu.

You’ll then be able to edit your existing collection:

Upload a new logo image, featured image, and banner image

When picking images (or changing images) for each of these fields, remember that high-quality images without any blurriness or unintentional pixelization are best. We also recommend that they don’t include words, specifically profanity. Consider the aspect ratio of each of these images and where they will be featured on the page. With this in mind, center subjects or portraits in the middle and arrange the essential parts of the image so they won’t be cut off or look incorrect. Lastly, there are instances in which multiple images are used to depict your collection in conjunction, so be sure to have distinct, separate images for all three of these uploads rather than the same image in three aspect ratios.

Hate speech is never tolerated on OpenSea, so please refrain from including hate speech or symbols in any images. Explicit and sensitive content is allowed on OpenSea, but must be labeled according to our policy, and will be handled differently than other content in search results.

Your image sizes should be as follows:

• Logo image: minimum 350x350 and under 1mb, 1:1 aspect ratio
• The logo is the small, circular image you see on the collection page on the upper left-hand side of the page. It serves as an icon or avatar for your collection.
• Featured image: minimum 600x400, and under 1mb, 3:2 aspect ratio
• The featured image will not show up on your collection page. Instead, it appears if your collection is featured in some places on OpenSea’s homepage or if your collection is featured on a category page. Because it often appears in conjunction with the logo image, make sure these are not the same image. This is also the preview image that will be shown if you share your OpenSea collection link on social media.
• Banner image: minimum 1400x350 and under 1mb, 4:1 aspect ratio
• The banner is the long image at the top of your collection page. This is the largest image, so it should always be high quality. It will also be many people’s first visual impression of your collection, so get creative with it!

Choose or change your collection name

Choosing a name for your collection is arguably the most important part of the process in that it will become the shorthand for your project. Consider the following when naming or changing the name of your collection:

• Your collection’s name should represent your work and the category you choose
• Remember that people often search for collections on OpenSea and other platforms, and if your chosen name is challenging to spell or remember, it will be harder for people to find your work
• You may want to choose a name that’s available on other platforms so you can have the same handle across the internet (especially on Twitter!)
• Consider choosing a name that doesn’t sound like other collections, so your project stands out and isn’t easily mistaken for something else
• Never use names with hate speech and avoid names with profanity
• Limit any drug references, and otherwise explicit language
• Don’t use trademarked brand names (unless, of course, you are that brand!) to avoid IP rights violations

Customize your collection’s URL

Ideally, your collection’s URL should match your collection’s name. If that’s unavailable, we recommend trying a variation on the name or using the creator’s name to identify the project and make it easy to find and evaluate.

Write or amend your collection description

This is your opportunity to give your audience an introduction to your collection and to you as a creator. When thinking about what to write, you can ask yourself what about your collection makes it stand out from others in its category. What inspired you to create the collection? What do you hope it accomplishes or gives people who buy NFTs from your collection? This is also a place to give some insight into yourself as a creator if you feel inclined.

Using the allotted 1000-character limit, your description should be creative and give insight into your collection. Illustrate the world you’ve created and why you created it. This is also a place to talk about the project’s purpose, plans (if it has any), vision, and why people should consider buying.

Choose or change your collection category and tags

Creators will soon be able to set new categories and tags for their collections. This will make it easier for creators to highlight what makes their work special on OpenSea and for collectors to find projects they care about. 

We’re introducing new categories: Gaming, Membership, PFPs, and Sports Collectibles, and we’ll be removing others that have limited use or are too broad (like Collectibles and Utility). Our categories will keep evolving alongside the ecosystem.

We’ll also add tagging so projects can make themselves unique within categories. For example, a trading card collection can better represent who they are within the Gaming category by choosing the Card Game, Strategy, and Turn by Turn tags.

We encourage creators to select a category and choose their tags. We’ve pre-set categories for some collections, but feel free to adjust and let us know if we are missing a category or tag.

Add or change your social media links

The easiest way for someone to further evaluate your collection (other than looking at the collection itself) is to give them easy access to your social media accounts. Linking from OpenSea to your social accounts connects your collection to a larger ecosystem, which gives casual viewers and collectors alike the opportunity to learn more about you as a creator, as well as the inspiration or meaning behind the project. And lastly, they can communicate with you and get involved in the ecosystems you’ve created across platforms, which helps build a loyal and robust community.

Link to your website

Linking to your project’s website is especially important if your project has a robust website with a roadmap, merchandise, and more. For example, World of Women uses its website to showcase its collections, merchandise, membership, and as a hub for links to its presence across all other platforms. This helps buyers evaluate the project, and it ensures that audiences have easy, clear access to all that a collection and community have to offer. It can serve as a tool for vetting, a selling point for prospective buyers, and a gathering place for your community.

If your collection doesn’t have a website, you can link to your personal creator website to give people a better understanding of who you are as an artist, creator, or entrepreneur.

Choose or change your display theme

OpenSea allows you to display your collection three ways: padded, which is recommended for media assets with transparent backgrounds, contained, which is recommended for assets that are not a 1:1 ratio, and covered, which is recommended for assets that can extend to the edge.

Set or change your settings to explicit & sensitive content

Setting your collection as explicit and sensitive content, like sexual and other not safe for work (NSFW) content, is required to protect users with safe search while browsing OpenSea. This switch can be toggled on and off, depending on the content of your collection.\

Toggle OpenRarity on or off

To provide a unified and transparent set of rarity rankings across our marketplace, OpenSea has adopted the OpenRarity standard—an open, transparent and reproducible standard for rarity rankings across the NFT industry.

We use “rarity” ranking to describe the relative scarcity of one NFT’s attributes compared to another in the same collection. An NFT with rare attributes will have a lower rarity ranking (such as 1 or 2) than an NFT that shares attributes with thousands of others in the collection.

OpenRarity is an open collaboration between OpenSea, icy.tools, Curio, and PROOF. 

We’ll automatically display OpenRarity rarity rankings for eligible collections on EVM chains with the following properties:

• Only ERC721/non-fungible items (no ERC1155/semi-fungible items)
• Only string attributes (no numeric attributes)
• Attribute information exists

We recommend only showing rarity if the collection is fully revealed and the item metadata won’t be changed.

Choose or change collection collaborators

Collaborators can modify collection settings, receive payments for items they created and create new items. Collaborators can be added at any time. To add a new collaborator, click “Add collaborator” and paste their wallet address into the field.

How can I get my collection verified?

A blue checkmark badge on a collection means the collection belongs to a verified account and has significant interest or sales. There are a variety of criteria that an account must meet in order to be eligible to apply for verification, including collection volume, activity levels, and social presence. If your account meets these criteria, you can apply for verification!
