Your current ranking is low because the title is too long and doesn’t closely match the search term “qr code.” The phrase “Ultimate QR Code Generator: Text, Wi-Fi & More” dilutes keyword relevance. Try renaming it to “QR Code Generator” for a much better match and likely higher ranking.
You might even receive a penalty for using the word ‘ultimate,’ since they’ve already mentioned that models and profiles containing terms like ‘best,’ ‘better,’ and similar could be flagged. However, this is speculative.
