Hello friends,

I Have Faced A Problem About website traffic So Please tell me How to block spam traffic?

Step 1: Clean Out Existing Spam. To remove spam from your existing GA reports, you can create a Custom Segment.
Step 2: How to Add Filters to Block Out Referral Spam.
Step 3: Block Common Spam Referrers.
Step 4: Block Third Party Traffic.

Hi,
Block the Referrer Used by Spam Bots
Block the IP Address Used by Spam Bots
Block the IP Address Range Used by Spam Bots
Block the User Agents Used by Spam Bots
Block Spam Referrers through Custom Advanced Filter in Google Analytics
Use the Google Analytics 'Bot Filtering' Feature

Blocking spam referral traffic is most effectively accomplished through a .htaccess (hypertext access) file. This is configuration file is used to control your server. It can be instructed to block spammy visits by domain or IP address.

Spam traffic is more than just annoying, it can be a serious security and performance risk to your small business website too.You need to take the time to analyse your website and Analytics data to make sure you're not dealing with any harmful spam traffic.
