−SEO tips
+
−========
+
−
+
−* Use pain text rather than images, CSS, JavaScript, Flash, SilverLite or other
+
−  technologies for important content.
+
−
+
−* Make sure your site work without with CSS, JavaScript, Flash, Java, etc
+
−  disabled. Check your site with screen reader or text browser (lynx, w3m).
+
−
+
−* Build valid HTML pages. Validate against W3C and other tools. Make site mobile
+
−  friendly and use the mobile friendly test.
+
−
+
−* Avoid HTML frames and iframes.
+
−
+
−* Market your site so other sites link to yours. The more valuable and relevant
+
−  site point to you the more rank you get!
+
−
+
−* Tend to focus on single topic per page.
+
−
+
−* Avoid cryptic URLs. Craft human attractive URLs as URL words directly can be
+
−  indexed. Use dashes instead of spaces.
+
−
+
−* Avoid duplication. Shutdown mirrors. Use ``<link rel="canonical" ...>`` tag to
+
−  point to page on main version from mirrors or page variants. Avoid page
+
−  variants (like embedding sid into URL). Use::
+
−
+
−    <link rel="prev" ...>
+
−    <link rel="next" ...>
+
−
+
−  to gather paginated content.
+
−
+
−* Tags ``title``, ``h1`` / ``h2`` / ``h3`` and::
+
−
+
−    <meta name="description" content="...">
+
−    <meta name="keywords" content="...">
+
−
+
−  have great impact. As usual make sure them have unique content across the web
+
−  and your pages.
+
−
+
−* Use keywrds for internal ``a`` links.
+
−
+
−* Add ``rel="nofollow"`` to spam or money making links.
+
−
+
−* Mark up site using microformats: ARIA, schema.org.
+
−
+
−* Keep navigational structure (global and hierarchical) easy to crawl.
+
−
+
−* Submit sitemap to search engine webmaster tools.
+
−
+
−* Ensure a fast load time and absent of HTTP errors.
+
−
+
−* Make site sharable across social media.

+
−* Use redirects when changes site structure. This usually move page value to new
+
−  page.

+
−* Produce new content frequently. That make crawlers visit your site more
+
