To programatically add tag to a product, try the below solution :

  $productIds = array(

$tag = Mage::getModel('tag/tag')
    ->load('my_tag_name', 'name');

    ->addRelations($tag, $productIds);

    this gives me an error of a:5:{i:0;s:214:"SQLSTATE[23000]: Integrity constraint violation: 1048 Column 'store_id' cannot be null, query was: INSERT INTO vwkvtag_relation (tag_id,store_id,product_id,customer_id,created_at) VALUES (?, ?, ?, ?, ?)";i:1;s:2375:"#0 E:\xampp\htdocs\magento\lib\Varien\Db\Statement\Pdo\Mysql.php(110): Zend_Db_Statement_Pdo->_execute(Array)

You can add a tag by below code:

$tagName=preg_replace("/(\'(.*?)\')|(\s+)/i", "$1\n", $tagNamesInString)
 $tagModel = Mage::getModel('tag/tag');

    // added tag relation statuses
    $counter = array(
        Mage_Tag_Model_Tag::ADD_STATUS_NEW => array(),
        Mage_Tag_Model_Tag::ADD_STATUS_EXIST => array(),
        Mage_Tag_Model_Tag::ADD_STATUS_SUCCESS => array(),
        Mage_Tag_Model_Tag::ADD_STATUS_REJECTED => array()


$storeId = Mage::app()->getStore()->getId();
if (!$tagModel->getId()) {

$relationStatus = $tagModel->saveRelation($productId, $customerId, $storeId);
