Audit HTML page size and identify oversized embedded JSON, SVGs, images, or scripts. Use the findings to plan lighter pages and investigate whether document size could explain content missing from Google's search index.

Googlebot has a documented crawl size limit of approximately 15MB per HTML document. Content beyond this threshold is not parsed or indexed. Excessively large HTML also slows Googlebot crawls, reducing how many of your pages are crawled per budget period.
<script> tagsMeasure the raw HTML response size (before compression) for each page. Flag pages over 2MB (investigate) and over 5MB (critical). Identify the cause of oversized HTML: (1) Large inline JSON (<script id='__NEXT_DATA__'> or similar). (2) Inline SVG files. (3) Base64-encoded images in HTML. (4) Inline CSS with large amounts of utility classes. (5) Unminified scripts in <script> tags.

getServerSideProps/getStaticProps — only pass what the page renders<img> or <use>.Google's crawl infrastructure parses only the first ~15MB of an HTML document. Pages that exceed this limit have their tail content silently omitted from Google's index. Beyond the hard limit, large HTML documents consume more crawl budget, meaning fewer of your pages are crawled per day. This particularly affects large e-commerce sites or pages that server-render large datasets into HTML.
Check the response Content-Length header or measure the raw HTML byte count. Inspect <script type='application/json'> or <script id='__NEXT_DATA__'> blocks — count their size in bytes. Flag any single block over 500KB. Check for inline SVG elements (look for <svg> in body HTML) that should be external files. Verify HTML is served with gzip or Brotli encoding.

Create and review custom 404 pages that help visitors recover from broken or moved links through search and navigation. Check the rendered page and HTTP response so missing content returns a proper 404 status.
