Keep it relatively short: it’s best to keep it at or below 125 characters.
Use keywords: Alternate text provides you the opportunity to include target keywords on your page.
Avoid accumulation of keywords. Google will not deduct your points for poorly written alternative text, but you may be punished for accumulating a large number of relevant keywords in the alternative text. Pay attention to writing descriptive, as far as possible to provide alternative text for the picture background, and include your target keywords.
Don’t use pictures as text. This is not an alternative text practice, but an SEO-friendly web development principle. If you use the image text, explain the content of the text in your image in the alternate text.
Don’t forget the form button. The picture button should have an alternative text describing the purpose of the button, for example, “search”, “apply now”, “sign up”, etc.
