SVG Crawl Experiment Two - December 2010

Aim: To determine what techniques for embedding SVG serve up the files so that they are crawled by google.

Method: Place a few differently named SVG files into a web page using different techniques and see which one appears in the search index.

Experiment:

Infographic 1: An SVG file embedded using the <object> tag

Infographic 2: An SVG file with the <embed> tag

Infographic 3: An SVG file with the <object> tag and wrapped with an <a> tag linking to the svg file

Infographic 4: An SVG file with the <embed> tag and wrapped with an <a> tag linking to the svg file.

Results:

days 1 - 2: nothing indexed by google

days 3 - 5: Infographic 4 starts appearing in natural search for the search term 'pro seo seminar 2010 fact and figures'. Infographic 4 also appears in search 'site:andyjamesdavies.com filetype:svg'

Interestingly /experiments/svg-two/ is not appearing in search index.

days 6 - 7: http://www.andyjamesdavies.com/experiments/svg-two/ starts appearing in the index.

days 8 - 9: infographic 3 starts appearing in google image search 'site:andyjamesdavies.com'.

day 10: infographic 2 starts appearing in natural search 'site:andyjamesdavies.com filetype:svg' but not natural search.
