Google advises businesses to build a site from the ground up with SEO in mind. By ensuring your coding is developed in such a way as to encourage a high level of usability and accessibility you ensure they are more easily readable by search engines. By doing this you allow more pages to be indexed and stored on Google’s algorithm.

Good HTML
Search engines prefer standards-compliant and semantically correct sites so make sure HTML code is well formatted and make suitable use of the H1, H2 and alt tags.
Reliability
A reliable site helps boost your search engine rankings. Firstly because customers appreciate it, return and boost traffic levels; secondly because if the Google bots which crawl your site cannot access pages, those pages cannot be indexed thus negatively affecting your rank.

googlebot only sees in your website is ‘text’ for them to categorize and indexed your website…they dont really care how good your design is…and of course the ‘relevancy’ of the content. Therefore, put great information in your content for them to hunt you down
Yes, of course that’s a valid point.
Googlebot may not care about the design, but humans do!!
What we’re trying to say is that whilst a robot cannot judge the quality of design, what you have to bear in mind, is that it’s not all about the robots! – You need to make sure that once a visitor is on your page, that the design is good, and the information is easy for them to read so that they stay on the page (or other site pages) which will have a positive knock-on result in the rankings.
Think of it a bit like skiing… If you only try pushing with one leg, you’ll never get anywhere!
