Pros & Cons
Keyword Insights
Pros
Clustering accuracy based on live SERP data rather than simple semantic similarity
Handles very large keyword lists (up to 50,000 keywords)
Expanded feature set covers briefs and full article drafting, not just clustering
Low-cost 7-day trial for $1
Team collaboration features on Professional and Enterprise tiers
Cons
Credit-based pricing can become expensive with heavy AI Writing Agent usage
Basic plan is limited to a single user seat
Enterprise pricing is not published and requires custom quotes
Focused mainly on clustering/strategy, less on technical SEO or backlinks
AI-generated content still typically requires human editing before publishing
theimageoptimizer
Pros
No account required to use the standalone web-based image compressor
States that uploaded images are never stored on its servers
Pay-as-you-go credits never expire, alongside monthly Standard/Agency plans
Dedicated Agency plan with multi-license management and consolidated billing for agencies managing several sites
Automatically converts images to modern WebP/AVIF formats
Cons
Paid use of the WordPress plugin and higher-volume compression relies on a credit-based license system rather than a flat subscription
Specific compression algorithm and quality-level details are not published on the site
No manual control over compression level is mentioned — format/quality selection is automatic
