Sure, let's break down the steps to solve the problem:

1. **Initialize a counter**: This will keep track of the number of steps taken to reduce the number to 1.

2. **Loop until the number is 1**: We will repeatedly apply the given rules until the number becomes 1.

3. **Check if the number is even or odd**:
- If the number is even, divide it by 2.
- If the number is odd, add 1 to it.

4. **Increment the counter**: Each time a rule is applied, increment the counter.

5. **Return the counter**: Once the number is reduced to 1, return the counter as the result.

Here is the step-by-step implementation:

```python
def numSteps(s: str) - int:
steps = 0
while s != "1":
if s[-1] == '0': # If the number is even
s = s[:-1] # Divide by 2 (remove the last character)
else: # If the number is odd
s = bin(int(s, 2) + 1)[2:] # Add 1 and convert back to binary
steps += 1
return steps
```

### Explanation:
- **Initialization**: `steps = 0` initializes the counter.
- **Loop**: `while s != "1"` continues the loop until the binary string `s` is "1".
- **Even Check**: `if s[-1] == '0'` checks if the last character of the string is '0', indicating an even number.
- `s = s[:-1]` removes the last character, effectively dividing the number by 2.
- **Odd Check**: `else` handles the case where the number is odd.
- `s = bin(int(s, 2) + 1)[2:]` converts the binary string to an integer, adds 1, and converts it back to a binary string.
- **Increment Counter**: `steps += 1` increments the counter after each operation.
- **Return**: `return steps` returns the total number of steps taken to reduce the number to 1.

This approach ensures that we follow the rules and count the steps accurately.
