    Bulk 301 Redirect Implementation
    4 μέρες left
    Βεβαιωμένο

    I need to move a large group of pages to new URLs and preserve all SEO value with proper 301 (permanent) redirects. At this stage I do not yet have a complete mapping, so I will rely on you to audit the site, identify every outdated link, and pair it with its new destination before putting the redirects in place. PAGES CAN BE SEEN HERE Most of the work will sit in two phases: • Discovery & mapping – crawl the site (Screaming Frog, Sitebulb, or a similar tool), export every legacy URL, match it to its new location, and flag anything that has no clear equivalent so I can decide what to do. • Deployment & testing – once the mapping is approved, write the redirect rules in the most appropriate layer for the stack (.htaccess or NGINX config are both fine), p...

    3 μέρες left
    Βεβαιωμένο

    I’m building a nationwide outreach campaign and need a clean, high-volume contact list before I can even think about drafting the first email. Your task is purely data gathering: deliver an Excel file containing roughly 300,000 unique, verified contact emails for churches across all 50 U.S. states. Coverage I’m interested in broad Christian representation, with a particular emphasis on Protestant and Evangelical congregations, but I’m not excluding other mainstream Christian churches if they surface during your crawl. Data fields required • Church name • Contact email (preferably a monitored, general-inbox or pastor/office address rather than a generic “info@” that never gets read) Quality expectations • No duplicates—one ...
