You create site to inform your visitors what is going on to your product, your service or even an announcement or news. But then search engines didn’t find or crawled the page you have created. There comes an issue of spiderability.

So what you do is optimize your site not just for your visitors but also for the spiders to crawl you site.

Navigation

Navigation makes it easy for both visitors and bots to run down on your site contents. What it has to offer and how I can find pages on your site from your home page.  I don’t think one will put navigation button link at the footer of the page where visitors needs to scroll way down just to go to a certain page.

Deeplink

How deep your site link is? The best approach is to have just one (1) to two (2) clicks away from your home page but can still go up to 3 to 4 deep from your main page. Spiders can easily index pages those pages that is few pages relative to homepage. Example, domain.com/page1.html can be index and crawled than that of domain.com/directory/page/content/page1.html. Though search engine can still indexed it and find it, but the priority would be that of near to the main page.

Sitemap

Sitemap plays a big role on site navigation, searches, spider and its importance to your niche. How each page points to your site main content.

 Emphasize Content

Emphasize content rather than  targeting other factors like monetization and neon color designs, etc.

Clean content and url’s 

Clean content without those keyword stuff, cloak or other factors and clean url’s by removing those session id making it hard for your spiders and visitors to remember those pages they have visited.
