When you increase the rate search engines crawl your website you are doing the most beneficial thing you can do for your site as far as generating more traffic is concerned. This "crawl rate" is the speed in which Google notices that your site has had new material added to it and indexed that material appropriately. For some websites a lot of time can pass from one crawl to the next leaving a lot of new material waiting and waiting to be indexed and ranked by Google. The best way to change this for your website is to make it more appealing to the spiders that crawl websites.
Increasing the page rank of your website and getting relevant backlinks is one of the key factors that you need to focus on in order to lay a solid foundation for the Google bots. Building extremely targeted backlinks from sites that Google already views as valuable in your niche or area is an excellent way to make Google believe your site has value. While it may seem difficult when your site is new this is one process that always delivers over time with greatly improved crawl rates. There is an unintended benefit to the process of building backlinks that leads to more traffic for you because your site will have better page rank too.
Never indulge in blackhat SEO techniques. Period. It really is in your best interest to be ethical in your search for search engine optimization and skip out on all the blackhat stuff completely. The downside of a blackhat solution is that the search engines don't respond well to this type of marketing and the results it providers can never be sustained for any major length of time. You might gain temporary benefits by using blackhat methods on your site, but eventually, they won't help you build sustainable traffic. In the end, crawl rates will be extremely slow because these tactics are not appealing to search engines. Common blackhat methods include keyword stuffing, doorway pages, invisible text, etc. If you're really interested in making the most of your site's crawl rates make sure that you're practicing proper SEO and giving your audience excellent and informative content.
Your title is an important tool in attracting readers as well as Google bots and should be on target and designed to appeal to your audience. You can kill two birds with the title stone by increasing frequency of search engine crawls and gaining higher page rank.
It doesn't take much to create unique titles for your content, but if you look at from the search engines point of view, it definitely is a big deal if you get them wrong. So ensure that you're focusing on this area too.
When you go out of your way to add value to your site for the people who visit, the search engines are going to see that and reward it well. Google's spider bots will appreciate the value of superb content designed with readers in mind far more than content designed to get the attention of the search engines. This will not only help the Google spiders, but it will also make your site more approachable to your visitors.
