Onpage optimization, as the name implies, is applying seo techinques on the web page so as to make search engine spiders index it and rank it higher.
Onpage optimization methods consists of –
Keywords – Here it means placement of keywords in the web copy and NOT selection of keywords. Keyword selection is done prior to writing content for web page and NOT as an afterthough ( although this is often the case ). Keywords must be placed in such a manner that both search spiders and visitors should be satisfied.
Title: In the title tag, the target keyword should appear at least once. (different title for each page). The title should entice the visitor to click to your site.
Meta Tags: Meta description tag – This tag summarizes the purpose of web page and like title tag, must include keywords.
The title and description should be appealing not only to the search engines, but to visitors as well. Search engines are not going to buy your products and services. Humans will.
Meta keywords tag – List of keywords seperated by comma is what goes into meta keywords list. (different keywords for each page).
Alt attribute: Using ALT attribute on images is good seo practice. “A picture is worth a thousand words” is not true in case of search engines, but ALT attribute is worth it. Don’t cram all the keywords in one ALT attribute. One or two keywords is sufficient.
Anchor Text: Internal links must be optimized with targetted Keywords.
HTML Site Map: HTML sitemap consists of links to all the pages of the website. This is useful in case of large website as visitor can quickly glance through all the pages to find the desired information.
