Set a Base in Airtable with a table with the following structure:\n  `url`, `title tag`, `meta desc`\n2. Connect Airtable to the nodes and, with the following formula, get all the records that miss `title tag` and `meta desc`.\n3. Put a bunch of url in the table in the field `url` and let the workflow work.\n\n## Extra\n\n* You can also calculate the length for title tag and meta desc using formula field inside Airtable. This is the formula:\n  `LEN({title tag})` or `LEN({meta desc})`\n* You can automate the process calling a Webhook from Airtable. For this, you need an Airtable paid plan."}, "typeVersion": 1}], "pinData": {}, "connections": {"Get records": {"main": [[{"node": "Get url content", "type": "main", "index": 0}]]}, "Get url content": {"main": [[{"node": "Extract title tag and meta description", "type": "main", "index": 0}]]}, "When clicking \"Test workflow\"": {"main": [[{"node": "Get records", "type": "main", "index": 0}]]}, "Extract title tag and meta description": {"main": [[{"node": "Update original record", "type": "main", "index": 0}]]}}}
