Support resolution rate
AIOSEO resolves 96.8% of support tickets, compared to LiteSpeed Cache at just 69.6%. If you hit configuration issues, you are far more likely to get a working answer from AIOSEO.
Specialized SEO feature set
AIOSEO delivers schema generation, local SEO modules, and SEO insights out of the box, while LiteSpeed Cache offers none of these. For on-page optimization tasks, there is no contest.
Higher per-user rating
AIOSEO scores 94/100 across 5,163 ratings, and LiteSpeed Cache scores 96/100 but on a smaller pool of 2,759 ratings. AIOSEO's much larger sample suggests broader user satisfaction with a heavier workload.
Where LiteSpeed Cache Wins
Massive install base
LiteSpeed Cache has 7,000,000 active installs, more than double AIOSEO's 3,000,000. That scale reflects how widely its caching benefits apply across virtually any WordPress site.
Quality score gap
Despite slightly lower overall scoring (94.84 vs 97.62), LiteSpeed Cache wins on ratings with 96/100 vs AIOSEO's 94/100. Users who leave reviews tend to be happier with its impact on perceived speed.
Performance ROI
Caching plugins deliver measurable load-time improvements on every pageview, while SEO plugins only pay off as Google re-crawls content. For an immediate, visible speed win, LiteSpeed Cache is the stronger tool.
Score-by-Score Comparison
LiteSpeed Cache wins here with a perfect 100/30 against AIOSEO's 97/30, backed by 7 million installs versus 3 million.
Both plugins tie at a perfect 100/25, with AIOSEO updated in July 2026 and LiteSpeed Cache updated in April 2026. Both are actively maintained.

The Bottom Line
For the most common WordPress use case, a content site that wants both speed and search visibility, you ideally run both plugins, as they do not overlap. If forced to pick one, AIOSEO is the safer choice thanks to its 96.8% support resolution rate and its direct impact on the ranking factor most site owners care about: search visibility. LiteSpeed Cache wins on raw install count and user rating, but its lower support score (69.6%) is a real risk on caching misconfigurations that can break a site. Choose based on whether your bottleneck is ranking or rendering.
