How long should your meta description be?
We want to be, as with any other content on our site, authentic, conversational and user-friendly. Having said that, in 2020, you will want to stick to the 155-160 characters limit (this corresponds to 920 pixels). We also want to keep in mind that the “optimal” length might change based on the query of the user. This means that you should really do your best in the first 120 characters and think in terms of creating a meaningful chain by linking the query, the title tag and the meta description. In some cases, within this chain it is also very important to consider the role of the breadcrumbs. As in the example above from WooRank I can quickly see that the definition is coming from an educational page of their site: this fits very well with my information request.
