Tips:
1. keep the number of links per page below 100.
2. having more than 100 links in a single page will lead to a bad user experience, and it possibly runs into the risk of been considered as spam.
3. search engines may not follow all the links if you have too many of them in a single page. |

search engines cannot `see` images, proper Alt content will help them to better understand and index images.
Tips:
1. always add alt attributes to images. Alt is mandatory for accessibility and for valid XHTML.
2. words used within an image`s Alt attribute should be its text equivalent and convey the same information.
3. use a human-readable caption and descriptive text around the image. |
