Block

A lot of time we get many requests from some bots we do not need here you can block them from htaccess file 

<IfModule mod_setenvif.c>
  SetEnvIfNoCase User-Agent (SemrushBot|Semrush|python-requests|sqlmap|wordpress|apachebench) bad_user_agents

  Order Allow,Deny
  Allow from all
  Deny from env=bad_user_agents
</IfModule>

you have to add this code to the block or to the page

 {{block class="Magento\Framework\View\Element\Template"  template="{Vendor}_{Module}::pages/example.phtml"}}

Example 

{{block class="Magento\Catalog\Block\Product\ListProduct" category_id="50" name="home.products.list.custom" template="Magento_Catalog::product/list.phtml"}}
