(
    select paid.keyword_id, paid.keyword_name, stat.orgEntrances,
    keyword.rank1, keyword.rank_check, 
    SUM(paid.clicks) as sumclick, 
    SUM(paid.clicks * paid.avg_position) as sumclickavgpos,
    SUM(paid.itemRevenue) as sumitem,
    SUM(paid.cost) as sumcost,  
    SUM(paid.transactions) as sumtrans,  
    SUM(paid.impressions) as sumimpress,  
    IF(SUM(paid.impressions) = 0, 0,
        SUM(paid.impressions * paid.avg_position) / SUM(paid.impressions))  
    as sumimpressavgrank,
    con.item_revenue,  con.transactions,  keyword.monthly_search_volume
    from `t_keyword_paid_analytics_google_ib` paid  
    left join
    (

        sum(outer_t.transactions) as transactions
        from t_keyword_conversion_ga_ib outer_t  
        where outer_t.own_domain_id = 720  
        and outer_t.traffic_date >= '2012-12-01'
        and outer_t.traffic_date <= '2012-12-31'

Please help me here.

Answer 1

Create index and change where condition. put (outer_t.medium = 'organic' or outer_t.medium is null ) after outer_t.own_domain_id = 720 and (paid.channel is null or paid.channel = 'Google') after paid.own_domain_id = 720. Try, i hope it will make your query faster.
