Good thread—lots of the usual on-page and backlink pitfalls are covered by , , and others. The short checklist below focuses on the technical, performance and monitoring gaps that are easy to miss yet cause long-term ranking and indexing problems.

Start with page experience: measure Core Web Vitals (LCP, INP, CLS) and treat them as priorities, not optional extras. Use PageSpeed Insights and Lighthouse to find the single biggest wins (reduce server TTFB, trim blocking JavaScript, serve sized/compressed images, enable caching/CDN). Small fixes here often move pages faster and reduce churn. (developers.google.com)

Fix how search engines see your site: canonicalization, parameter handling and redirect chains cause duplicate-index issues and wasted crawl budget. Pick a canonical URL pattern, eliminate redirect chains with 301s, and test robots.txt so you aren’t accidentally blocking CSS/JS or key pages. If the site is multilingual, implement and test hreflang properly rather than guessing. These steps stop index confusion before it starts. (developers.google.com)

Add the last-mile technical pieces most threads skip: implement JSON‑LD structured data for pages that qualify (products, reviews, breadcrumbs) to improve CTR; migrate fully to HTTPS and resolve mixed-content; and run periodic log-file analysis to see exactly what bots crawl and when. Also audit internal linking so authority flows to conversion pages, and fix orphan pages. These items lift visibility and make recovery faster after changes. (developers.google.com)

Quick practical start: run one PageSpeed Insight, export a crawl (Screaming Frog or similar), review server logs for 404/5xx patterns, and fix the top five heavyweight pages (largest LCP or largest bytes). That single cycle turns theoretical “SEO work” into measurable improvements.

1.first of all we don't do keyword reaserch and after site is ready than we run for SEO. I mean lacking Due diligence

like choosing name of business : suppose you do not check business names in your locality or in same service area over the web. and if similar business name do exist than you are at a loss since some or most of traffic that should come to you, go to other similar name site(provided that they have done better SEO).

secondly, when buying domain names, either we don't include keywords in our domain name, and if we do, then we don't provide gap between keywords using -(recommended) or _(not recommended).

  1. Black hat SEO: to increase site ranking some time we overdo some things, like keyword stuffing where web master stuffs meta tags with extraneous keywords in order to gain search engines attention.

Well, that looks like everything is added over here ! Okay, what more I think I can add over here's not registering yourself for Google Analytics as well as Google Webmaster tool !

A lot of SEO experts choose anf focus primary keywords and that is big mistakes for getting better results. Need to choose keywords for all landing pages of a single website.

For Expample: You can choose seprete keywords for all your services pages.
