Keep Your Site Always Accessible
Taking your site down offline, due to maintenance for example, is bad for search engine optimization (SEO) as this will upset visitors especially regular readers. Even worst is if search engine robots crawl your site when it is down. Your site will be assumed to have expired and lost its position in search engine results pages (SERP).
To climb up the search engine rankings afterward when it’s up online would require full SEO effort again. It’s better for you to put up a mirror site when your original site needs to go offline.
If the site is a business portal and you’re not able to attend to it, say during vacation, it’s best to just let it up and running than to have it down. One advantage is that when it’s online your site has a chance to climb up the SERP. You can place a note saying that you’re not available during a certain time to avoid confusion or have forms for them to still place orders.
Spend Time and Money Wisely
There are tendencies for people who don’t know SEO to hire SEO companies to improve SERP positions drastically. Largely, these are spamming. Most of these companies will build large number of links to your sites. What people don’t know is that the links come from unrelated sites that aren’t counted as valuable to get your position up in SERP.
Search engines also have the ability to detect suspicious links, especially a large number of them and may penalize you for that. As a rule of thumb, good links take time and don’t come cheap.
Search engine crawlers eventually will index your new site, so it’s a waste of time to submit the URL yourself to search engines (although there are tips that say otherwise).
Submitting your URL to directories also have less effect on SERP nowadays compared to a few years ago because today’s search engines have more advanced and improved criteria indexing sites and blogs – most directories are now classified as link farms only, which is not seen as valuable links.Submitting to manually edited site like Wikipedia won’t do any good because they are set with a “nofollow” property, meaning that crawlers do not follow outbound links.
Compromising Content is a Bad Thing
The strategy of splitting content in subdomains to gain more spots in SERP is not a good one. It risks visitors’ experience as the contents are divided in different subdomains or even domains making it harder to find. In the long term, your readers’ bad experience dominates and affects your site negatively in terms of traffic and in the end conversions to revenues.
There are reports mentioning that some sites aren’t crawlable and thus won’t lendthem positions in SERP. Some of the main causes are:
Don't Abuse Keywords
Today’s search engines are advanced enough to have the ability to detect keyword abuse as spamming. And, they’re advanced enough to penalize those sites that do this. Types of keyword abuse include:
