Google prefers hyphens to spaces or underscores in alt tags when using multiple words. This is because hyphens are more descriptive and easier for screen readers to understand.

For example, the alt text "black cat" is more descriptive and informative than "black_cat" or "black cat".

If you have so many links from a single site, it's important to assess the quality of those links. If they are coming from a high-quality site with relevant content, then they may be beneficial for your SEO. However, if they are coming from a low-quality site or a site that is irrelevant to your niche, then they could actually hurt your ranking.

In some cases, having too many links from a single site can be seen as a sign of link manipulation, which could lead to a Google penalty. If you're concerned about the number of links from a single site, you can use Google Search Console's Disavow Tool to tell Google to ignore those links.

To get Google reviews on search results, you need to:

1. Claim and verify your Google Business Profile. This is a free listing that allows you to manage your business information on Google Search and Maps.
2. Encourage customers to leave reviews. You can do this by adding a link to your Google Business Profile to your website, email signature, and social media pages. You can also ask customers for reviews in person or over the phone.
3. Respond to all reviews, both positive and negative. This shows that you value customer feedback and are committed to providing a good experience.
