how can we promote hundred of keywords at a time ?

[Ali12]

Deploy a keyword‑matrix engine in your CMS. Tag each article with a batch ID, pump out title tags, meta blobs, and H1s driven by a master spreadsheet.

Use LSI synonyms to dodge cannibalization, feed the sitemap to Googlebot daily, and let the internal link juice funnel to the pillar pages. With header hierarchy and lazy‑load assets, you can spin up hundreds of micro‑pages that get indexed on autopilot.
