    Fantastic platform but introduce a ‘starter tier’

    Can’t knock the platform - it’s great. I feel like they should have a paid-for offering at a lower price point, however. Strongly recommend!

    Easy to use with limited trail but prices are high expensive - Semrush

    Semrush is very popular and next level performance tool which varies competitors, analyzes and tracking of any domain website, which provides you full information what's the position of the website, overall traffic, etc. This tool is easy to use with limited trial 7 days, after the trial ends, has limited features work on free plan. There plans are very expensive, not affordable at purchasing price plans.

    In my experience, semrush is very costly and high level of experience.

    🏁 Competitors: Ahrefs, Moz, SE Ranking, Marketing Miner
    👍 Pros:    Real-time analytics|Excellent features|Simple yet powerful and efficient tool
    👎 Cons:    Pricing is too high|Limited features with free plan.

    Great keyword tracking platform, shame they removed the display advertising report

    SEMrush provides a great central hub for adding your websites as projects which can be tracked, audited and measured for visibility over time. I've used the platform across many roles and found the only recent drawback was the removal of their display advertising competitor reports.
