Before you dig into some of the more technical ways to improve SEO ranking, always remember that writing compelling, high-quality content that attracts interest and compels visitors to share it and link back to it is vital. Good content has the best chance of being viral content, and Google rewards content virality heavily in its rankings algorithm.
The fee structure is both a filter against superfluous submissions and a revenue generator. Typically, the fee covers an annual subscription for one webpage, which will automatically be catalogued on a regular basis. However, some companies are experimenting with non-subscription based fee structures where purchased listings are displayed permanently. A per-click fee may also apply. Each search engine is different. Some sites allow only paid inclusion, although these have had little success. More frequently, many search engines, like Yahoo!, mix paid inclusion (per-page and per-click fee) with results from web crawling. Others, like Google (and as of 2006, Ask.com), do not let webmasters pay to be in their search engine listing (advertisements are shown separately and labeled as such).
Internet marketing professionals refer to search that isn’t organic as paid search. Instead of organically, or naturally, reaching the top of the search results for a particular keyword, businesses can pay to get noticed. So, paid search is a bit like doing a local endorsement, TV ad or radio spot—but for the internet. When a consumer types in a search term that you’ve incorporated into your campaign, your ad will show up at the top of search page results, above the organic results. Sometimes, your ad may appear in the sidebar. Only if the consumer clicks on your ad do you pay anything.
To avoid undesirable content in the search indexes, webmasters can instruct spiders not to crawl certain files or directories through the standard robots.txt file in the root directory of the domain. Additionally, a page can be explicitly excluded from a search engine's database by using a meta tag specific to robots. When a search engine visits a site, the robots.txt located in the root directory is the first file crawled. The robots.txt file is then parsed and will instruct the robot as to which pages are not to be crawled. As a search engine crawler may keep a cached copy of this file, it may on occasion crawl pages a webmaster does not wish crawled. Pages typically prevented from being crawled include login specific pages such as shopping carts and user-specific content such as search results from internal searches. In March 2007, Google warned webmasters that they should prevent indexing of internal search results because those pages are considered search spam.
Cost and Sustainability. While it’s not totally free and easy, SEO can be more cost-effective in the long run as it will give you a targeted and relevant results that you are aiming for your business. With regards to sustainability, even with the smallest of a budget, you can still develop a plan that will still give you the quality of results and still keep the traffic that your business is getting.
