        <strong>
          The <dfn>bot</dfn> specifies a manipulation to be applied to the medium when search engine
          bots are visiting.
        </strong>
      </p>
      <p>
        Its goal is to optimize SEO by always giving the same image to the search engine bots even
        if they emulate different devices.
      </p>
      <p>
        The syntax is a slash-separated list of <a
          href="https://www.twicpics.com/docs/api/transformations?utm_source=github&utm_medium=organic&utm_campaign=components"
          target="_blank"
          rel="noreferrer"
        >
          TwicPics API transformations</a
        >.
      </p>
      <p>
        In the example bellow, <Code>bot</Code> has been set to "cover=400x400".
      </p>
      <p>
        While regular visitors will receive different variants depending on their browsing context,
        search engine bots will always get a 400 pixels wide, 400 pixels high version of your image.
      </p>
      <p>
        <strong>Sets your browser's user agent to a bot engine value</strong>
        to see how bots will perceive the images. Note that context changes then have no effect on the
        delivered image.
