Google's parent company Alphabet Inc. has two publicly traded stock classes: Class A shares (stock code: GOOGL) and Class C shares (stock code: GOOG). The main differences between these two types of shares lie in shareholders' voting rights and their market performance.

1. **Voting Rights**: GOOGL shareholders have voting rights, with each GOOGL share typically granting the holder one vote, allowing them to participate in major company decisions such as board elections and significant strategic changes. In contrast, GOOG shareholders do not have voting rights.

2. **Market Performance**: Due to the difference in voting rights, GOOGL shares usually trade at a slightly higher price in the market, reflecting the value of voting rights. However, the fundamental economic interests of both share classes are the same, meaning they have equal rights to the company's profits.

3. **Dividend Distribution**: GOOGL and GOOG shares enjoy the same dividend distribution rights, with Alphabet applying the same dividend policy to both share classes.

4. **Liquidity**: GOOGL shares typically have higher trading volumes, making them more liquid and easier to buy and sell. GOOG shares, on the other hand, have lower trading volumes and relatively weaker liquidity.

5. **Investor Choice**: When choosing which shares to buy, investors need to consider their investment strategy and their desire to participate in corporate governance. Investors who want a say in company decisions may opt for GOOGL shares, while those who prefer passive investing without involvement in governance may choose GOOG shares.

6. **Company Control**: Alphabet's founders, Larry Page and Sergey Brin, also hold Class B shares, which grant them more voting rights per share, ensuring they retain actual control and veto power over company decisions.

7. **Risk and Return**: Despite the differences, GOOGL and GOOG shares exhibit similar levels of risk and return over the long term, as they reflect the same underlying business performance of Alphabet.
