Recently someone has asked in twitter to Google’s John Mueller if using stock images affects rankings.
John Mueller answered:
“It doesn’t matter for web-search directly.”
The search results are full of top-ranked sites that use stock images which are generally non-original content.
If Google took off marks for the use of those, half the Internet would never rank.
How can you use stock pictures in SEO?
Before choosing the stock images, here are some points to keep in mind
1. Choose the image which fits best for your topic.
2. Choose the relevant image for the featured snippet. This will communicate very well among users about the topic.
3. Select the image which can give you a conversation.
