How to Choose an AI SEO Tool
When evaluating SEO tools for your small business, consider five factors: the size and freshness of the keyword database (more keywords means better long-tail discovery), the depth of the backlink index (critical if link building is a priority), AI content features such as brief generation and writing assistance, local SEO support if you serve a geographic area, and pricing that fits a lean budget without crippling usage limits.
