Add a string to the start of a retailer class title

I wish to add to the start of the title of my website content material within the textual content retailer class
Word: It’s not WooCommerce and I don’t use the plugin in any respect
Code snippet:

<?php if( is_category( 'store' ) ) : ?> 
    <h1><title><?php wp_title( ); ?></title></h1> 
<?php else : ?>
    <h1><title>مشخصات قیمت و خرید <?php the_title(); ?></title></h1> 
<?php endif; ?>

I used this code within the header part
