Weeks 104: Keyword Research and Content Foundations

Weeks 104 are for finding the right keywords and publishing the pages that matter most. Start with a short keyword inventory that separates buyer-intent phrases from informational queries. You want a mix: a few commercial pages that can convert visitors, and several informational posts that attract search traffic early.

Use low-cost tools for keyword research and SERP checks. A practical method is an effort-vs-impact score: estimate search volume and competition, then score the effort to rank. Prioritize high-impact, low-effort keywords first and map them to specific pages.

Must-publish pages for small businesses in your first month:

  1. Homepage optimized for your primary service keyword
  2. Services or product page with clear buyer intent focus
  3. About page with local/business details
  4. Contact page with NAP (name, address, phone) and map
  5. 3 blog posts targeting low-competition informational queries
  6. One cornerstone page that links to related posts

💡 Pro tip: Prioritize 35 low-competition buyer-intent keywords you can realistically rank for in 90 days and create one focused page per keyword. Repurpose existing business copy to speed publishing.

If you want a deeper how-to on keyword research, see the Moz SEO Guide for practical examples and tools that help validate search intent. Then map top keywords to the pages above and schedule them in a simple content calendar.

Weeks 508: On-Page Optimization and Internal Linking

With pages published, optimize them for ranking. Focus on title tags, meta descriptions, header structure, and simple schema where it helps (local business, FAQ). A clear title tag that includes the target keyword and a local modifier when relevant is enough for many small businesses.

Example title variations for a service page targeting seo for new website: “Local SEO for New Websites  Your City | Agency Name” or “SEO for New Website  Fast Setup Checklist”. Keep headers logical: H1 sets the page topic, H2s break sections, and H3s hold details.

Internal linking pattern for a small site: each new blog post should link to 23 related pages — one service page and one cornerstone article. This guides crawlers and helps pass relevance to priority pages. For social signals and promotional crosslinks, see our Social Media Marketing page for content ideas that work with SEO.

Weeks 912: Authority Building, Monitoring, and Iteration

Now that pages are live and optimized, start modest authority work and set up a weekly monitoring habit. Outreach for a new site should be low-effort and local: claim local citations, ask vendors or partners for a mention, and post guest advice to relevant community sites.

Simple outreach sequence: 1) Make a small list of 10 local partners, 2) Send a short personalized email asking for a vendor mention or testimonial link, 3) Offer a short guest post or resource in exchange. Track responses and add any mentions to your monitoring sheet.

KPIs to track weekly: impressions and clicks in GSC, organic sessions in GA4, rankings for 5 priority keywords, and top 10 placements count. Example targets for month 1month 3: low-competition keyword rankings in the top 50 by week 4, top 20 by week 8, and top 10 for a subset by week 12. If growth stalls, refresh content or expand outreach.

📌 Key takeaway: Measure weekly trends (impressions, clicks, and top-10 rankings) and iterate content rather than chasing hourly rank changes. Small, consistent improvements compound into measurable traffic by month three.
