There is no definitive answer to which Instagram hashtags get the most likes, as the popularity of hashtags can change over time and vary depending on the specific niche or community. However, there are a few general strategies that can help increase the chances of a post being seen and liked by a large audience.

One strategy is to use popular and widely-used hashtags. These are hashtags that are commonly associated with a particular topic or theme, and are used by a large number of Instagram users. Examples of popular hashtags include #love, #instagood, #photooftheday, #beautiful, and #fashion. By using these hashtags, a post is more likely to be seen by a large number of users who are interested in the topic or theme.

Another strategy is to use specific and niche hashtags. These are hashtags that are associated with a specific niche or community, and are used by a smaller number of Instagram users. For example, if you are a fashion blogger, you may want to use hashtags such as #fashionblogger, #styleinspo, or #outfitideas. By using these hashtags, a post is more likely to be seen by a smaller but more engaged audience who is interested in the niche.

A third strategy is to use location-based hashtags. These are hashtags that are associated with a specific location, and are used by Instagram users to discover content from that area. For example, if you are traveling to Paris, you may want to use hashtags such as #parisjetaime or #cityoflight to attract attention from other Instagram users who are interested in Paris.

It's also important to keep in mind that using too many hashtags can make a post seem spammy, and can actually decrease engagement on the post. Instagram allows 30 hashtags per post, and it is generally recommended to use around 11-15 relevant hashtags for each post.

Another important point is that the hashtags should be relevant to the post, using irrelevant hashtags will decrease engagement and decrease the likelihood of the post getting seen by the right audience.

Additionally, it's worth considering that hashtags trends are changeable, and most trending hashtags change often, so it's important to stay updated with the most popular hashtags to ensure that your post is reaching the widest audience possible.

In conclusion, there is no one-size-fits-all answer to which Instagram hashtags get the most likes, and the best strategy will depend on the specific niche or community of an account. However, by using a combination of popular, specific, and location-based hashtags, and by staying up-to-date with the latest trends, it is possible to increase the chances of a post being seen and liked by a large audience.
