Rule budget.disallow_linked · Budget · 3 occurrence(s)

  • https://marinkids.kr/kakao_login.php — internal links point to https://marinkids.kr/kakao_login.php, which robots.txt disallows for Googlebot — Googlebot discovers the URL, checks robots, then rejects it without indexing, wasting crawl budget and losing the link equity. Remove the internal links, or use noindex instead of Disallow if the page should be fetchable. Linked from: https://marinkids.kr/register.html, https://marinkids.kr/visit.html, https://marinkids.kr/parents.html.
  • https://marinkids.kr/videos.php — internal links point to https://marinkids.kr/videos.php, which robots.txt disallows for Googlebot — Googlebot discovers the URL, checks robots, then rejects it without indexing, wasting crawl budget and losing the link equity. Remove the internal links, or use noindex instead of Disallow if the page should be fetchable. Linked from: https://marinkids.kr/, https://marinkids.kr/pricing.html, https://marinkids.kr/visit.html.
  • https://marinkids.kr/welcome.html — internal links point to https://marinkids.kr/welcome.html, which robots.txt disallows for Googlebot — Googlebot discovers the URL, checks robots, then rejects it without indexing, wasting crawl budget and losing the link equity.

Rule budget.noindex_linked · Budget · 2 occurrence(s)

  • https://marinkids.kr/makeup.php — this noindex page has 11 internal inlink(s) — Googlebot follows them, fetches the page, then drops it unindexed, spending crawl budget for no indexing benefit (and the links leak equity).

  • https://marinkids.kr/waitlist.php — this noindex page has 1 internal inlink(s) — Googlebot follows them, fetches the page, then drops it unindexed, spending crawl budget for no indexing benefit (and the links leak equity).

  • https://marinkids.kr/gallery.php — the likely hero/LCP image (viewing.jpg) has loading="lazy" — Google explicitly warns against lazy-loading the LCP image, because it delays the fetch until layout completes.
