Transcript

  • 1. SEO for Developers
  • 2. Why do I need to know about SEO?
    • Onsite optimization is done by developers
    • 3. Website without onsite SEO is harder to rank
    • 4. SEO should be planned before building the site
  • 5. Understanding crawlers
  • 6. Understanding crawlers
  • 7. HTML Tags
    • <h1>, <h2>, <h3>, etc.
    • 8. Use <p> where it makes sense (wrap around paragraphs in articles)
    • 9. Alt-tag on images (<img alt=”desription”)
  • 10. HTML tags (header part)
    • Title
      • Google reads long, but shows only 60 characters
    • Meta description
      • Max 160 characters
      • 11. Unique for every page!
      • 12. Not a ranking factor, but increase CTR on SERP
  • 13. HTML tags (header part)
    • Meta keywords is useless
      • Bing reads them, but can be seen as spam warning
      • 14. Search Engine Land: http:// l.ff.pe/pqYz48
      • 15. In short: don't use meta keywords
  • 16. Duplicate Content (DC)
    • Short definition: 2 URL's with identical content
    • 17. Example:
      • Store.com/flowers/green/big-tulipan
      • 18. Store.com/flowers/blue/big-tulipan
      • 19. www.mysite.com/
      • 20. mysite.com/
    • Does not have to be 100% identical
  • 21. Dealing with DC
    • 301 Redirects
      • Most common example:
      • 22. Www.domain.com -> domain.com
      • 23. domain.com/old-file -> domain.com/new-file
  • 24. The Canonical tag
      <link rel=&quot;canonical&quot; href=&quot;http://businessperu.net/&quot; />
    • Use full URL
    • 25. Careful, is used strongly be Google
    • 26. Don't rely 100% on Canonical
  • 27. URL Structure
    • Think about it before you start code!
    • 28. For content-rich sites (ex. Thousands of records) split into categories, tags, etc
    • 29. Examples:
      • businessperu.net/restaurants/french-cuisine/miraflores
      • 30. / <category> / <sub-category> / <city>
  • 31. Breadcrumbs
    • Good for using with URL structure
    • 32. Great for dynamic & user generated content
    • 33. Both for users & search engines
      • <category> > <sub-category> > <city>
  • 34. Robots.txt
    • Use to block pages & part-content
    • 35. Helpful for block fx. Tabs & avoiding DC
    • 36. First thing Googlebot looks for
  • 37. Use “site:” search on Google
    • Always keep an eye on how many pages indexed
    • 38. Check how your pages look in SERP
    • 39. Control your meta description tags with “site:”
  • 40. Google Webmaster Tools
    • google.com/webmasters/tools/
    • 41. Crawl Errors – check often (after shipping!)
  • 42. Google Webmaster Tools
    • Use HTML Suggestions
