However, there is something we need to know before we start any real SEO work – the direction of our entire SEO campaign – What we are trying to achieve? What are our targeted keywords? Who are our competitors? That led us to the most important preparation work before any SEO campaign get started – keyword research.
Keyword research is crucial as it acts like a compass for your website or blog. A proper keyword research reveals the supply and demand trends in your industries thus giving general idea on which keyword you should focus on.
In brief, here is how you can do a keyword research:
- Get a list of related keywords using Google Keyword Tool
- Search each keyword to check how many websites turned out on the search engine result page (SERP) – this fits in as the number of supplies.
- Websites topping the SERP are your major competitors, study them well.
- To learn what are the demands, check number of searches for each keyword using keyword tools.
- Tool suggestion for keyword research: Word Tracker and Keyword Discovery – these two are my favourites.
Well, now you have a rough idea on your competition. The smart approach is to be a big fish in a small/average pond – for starters, you should focus your work on keywords with moderate demands and low competition.
Besides supply and demand, keyword research also offers valuable information for your web designs. Take example that you are selling shoes online, I am sure you’ll have questions like: What are the popular brands searched online? How shoes should be categorized – based on brand, occasion, or sizes?
All these can be answered as you run down the keyword research work. You’ll see searches come in based on brands, like ‘DC shoes’, ‘jordan shoes’, ‘nike shoes’; in the same time, searchers are also looking for shoes for different activities or occasions, like ‘ballet shoes’, ‘safety shoes’, ‘bowling shoes’, ‘prom shoes’, and so on.
By the end of your research work, you should be able to generate a list of target keywords. And now it’s the time to focus your SEO work on them. To get started, here are the 10 key elements that will improve your blog or website’s SEO quality immediately. 10 key elements that improve your website SEO quality immediately:
1. Index-able and Keyword-rich URL
The power of a keyword rich URL is often overlooked by bloggers and webmasters. In case you have yet to registered your domain name, try include your primary keywords in your domain; while for those who are already running a website, a keyword rich URL (example: abc.com/keyword) still helps a lot. One might complains that domain name with keywords faces branding problems and hard to be remembered; but that’s the dilemma every webmaster/blogger has to face.
Also, a good SEO practice is to avoid complicated dynamic URL that is hard to be indexed. Try limit your URL to 2 – 3 variables, excessive usage of ?, $, &, +, % characters as well as cgi-bin redirect will only do you harm.
2. A reliable web hosting
Website with poor uptime will never rank high on search engines. Let’s imagine that you are the search engine, how would ranking a down website on top of your search result page looks like? Awfully bad, don’t you think? Hence, hosting your website on a reliable web hosts – dedicated or shared, is very crucial.
To pick up the right web host, you can always hang around reputable hosting forums like WebHostingTalk.com or you can read my personal hosting reviews here.
3. Keyword-rich title and heading tags
A keyword-rich page title is as crucial as a keyword-rich URL for a few reasons.
One, a keyword-rich title tells the search engine bots what the page is about thus grouping your webpage into the right category; second, most search engines will bold your keywords in title whenever that particular keyword is searched. Common sense, the bolding effect will definitely draw extra attention from the searchers and thus, brings more clicks into your website/blog.
Heading tags (example <h1></h1>) is hard to be missed in old times. Not now anymore. As more and more websites are built solely on blogging software like Typepad and WordPress, heading tags are often put in the wrong use.
Take Wordpress (WP) templates for example, WP themes designers often use heading tags for sidebar titles without relevant keywords (example: Achieve, Categories) which bring no SEO value at all. To make sure your blog is well SEO-ed, one top thing to do is to remove or modify these headings into keyword-rich headings.
4. Alt tag on images
In term of SEO, putting descriptive alt attributes with your image places additional relevant text to your source code. Search engines like this and the more relevant text you have the better chances you get to rank higher.
As an additional benefit, a descriptive image alt tag helps users to understand your image when it fails to load.
5. Proper structured internal linking
Search engines pay a lot of attention to links – both internal and external. As internal links are those that can be controlled by you, make sure your website internal linking is proper structured and filled with relevant descriptive keywords. A plain anchor text like ‘click here’ and ‘read more’ are not clever; ‘click here for more Jordan shoes’ and ‘read more about ballet shoes’ are.
For website owners, make sure there are plenty enough of internal links pointing to your primary pages; for bloggers, mentioned and linked to your previous blogpost whenever it’s appropriate, this give extra link juice to your previous blogpost (hence better rankings) plus it enables your readers to catch up what they missed.
6. Inbound links
Link development is an inevitable process if you want your website to rank high. The keypoint, however, is not to obtain links blindly from spammy websites and directories. Always emphasize quality on top of quantity when you’re building links.
There are wide options for your link building campaign: from submitting your sites to reputable directories to asking for a link exchange; from buying text link ads to writing guest blog post in your industries – some of these methods can be risky (of search engine’s filter and bans) and some are not. What you need to do is to pick a series of method you feel comfortable with and pour some sweat in the link building campaign.
7. XML sitemap
XML sitemaps is used for search engine bots indexing. It runs as a list of all pages and posts along with related information like priority of each page and the date of creation. These elements help search engine bots to crawl your websites/blogs as well as learning the importance level of each page.
While XML sitemap is not a must for a website to rank high, it is however good practice for web and blog owners to have it on site.
8. WWW/non-WWW Canonical Issue
Originally, all websites built can be viewed in two versions: the WWW and the non-WWW version. In normal cases, the search engines should be able to recognize the issue and rank the websites accordingly but occasionally it fails. This led to serious problem where websites are penalized (especially on Google) due to content duplication. Even if there’s no penalty imposed, the web page indexed twice will have hard time to rank high as the back links are (PR/anchor text) shared over two web pages.
The solution of this problem is simple. One, you can login to Google Webmaster Tools and tell them which version (WWW or non-WWW) of the website is preferred. Alternatively, a simple 301 redirect code in your .htaccess file is sufficient to solve the problem.
Example code:
To have your website in WWW version
RewriteEngine On
RewriteCond %{HTTP_HOST} !^www".example".com $
RewriteRule (.*) http://www.example.com/$1 [R=301,L]To have your website in non-WWW version
RewriteEngine On
RewriteCond %{HTTP_HOST} !^ example".com$
RewriteRule (.*) http:// example.com/$1 [R=301,L]
9. Robots.txt
Robots.txt simply tells search engine bots what to crawl and what not to. It might not help that much in website rankings but it prevents irrelevant objects to be related to your website – which is good for your website to look focus (in search engine eyes) and professional.
10. Content is king
Users do not search for fun, they search for information and solution to a problem. If your website or blog does not offer what the users want, they will move away. As what had been widely covered by Nathan’s post about increasing and maitaining blog traffics, you should know attracting traffics via SEO is just the beginning; the key point of having a successful website is always having an informative website that solves human’s needs.

Q: How long does it take to get Indexed.
Q: How long does Google take to Index a site.
Q: How fast does Google Index a site.
Q: Still not Indexed.
Q: How long does it take to get Crawled.
Q: How long does Google take to Crawl a site.
Q: How fast does Google Crawl a site.
Q: Still not Crawled
.
============= How long to get indexed =================
There is No set time in for Google to initially index your site - the time taken can vary.
The time it does take may vary based upon factors such as;
* Popularity of the site (Whether it has any links to it)
* Whether the content is Crawl-able (Server Responses and Content type)
* Site structure (how pages interlink)
It is possible for a site to be crawled/indexed within 4 days to 4 weeks.
In some cases, it may take longer.
## Things to do to check/ensure that things are "optimal" for crawling/indexing ##
* Check Server responses
Pages should return 200/OK responses.
Use tools like http://oyoy.eu/page/headers/ to check the response.
* Have actual "content"
This means having content that bots/spiders can "see" and understand (text!).
If you are using purely Images, solely Flash or loading content up via JavaScript - then you are likely to encounter problems.
Remember - bots like to "read" - so ensure that you have "text" for them to read!
* Use "normal" links
Normal links are things such as <a href="some_URL" title="optional"> Some Link Text </a>
Using JavaScript based events (no href value, instead using on.click or using select list elements with on.click functions etc.) may result in the bots not following!
* Submit the site
NO - Verification is NOT the same as Submitting.
To submit your site - use the URL Submittal tool http://www.google.com/addurl/?
* Be discovered
If at all possible, have a few links to the site from other sites.
These links should be from related/topical/relevant sites.
These links should be from quality/trusted/popular/
Links do seem to help - but do NOT go overboard - it only needs 1 link that is "normal" (can be seen/followed by bots).
* Verify your site
Sign up for a Google Webmaster Tools account.
This does NOT mean the same as Submitting your URL!
This MAY NOT improve the chances of getting crawled/indexed.
This can help in discovering/locating/
* Provide a Sitemap
This is completely Optional!
Sitemaps do NOT guarantee getting Crawled/Indexed.
Sitemaps MAY NOT increase your chances of getting crawled/indexed, nor improve the speed/rate.
## Common Problems/Causes for initial Crawling/Indexing ##
* Poor Server responses...
- The server sending Bad Responses (404/410/500 etc.),
- The server being Slow/Timing out (taking ages to acknowledge/reply to the server request),
- Having Excessive Redirect Strings (Redirect from URL A to B, to C, to D etc.),
- Using non-standard Redirects (JavaScript etc.),
...may result in the initial crawl getting stuffed.
* DomainNameServer responses...
...that fail to resolve or that have major issues can cause problems.
* Really shoddy code/markup...
...such as seriously malformed <head></head> sections etc. can cause problems.
* robots.txt ...
- being malformed,
- being incorrectly setup,
- not returning a proper response code,
...can cause crawling issues
* robots meta ...
...people may have unwittingly blocked bots, included multiple/additional robots tags and unknowingly be denying bots to ability index/follow pages.
## Additional ##
Please, before deciding that your site is Not Indexed ...
1) Be aware that information/data in the Google WebMaster Tools (GWT/GWMT) may not be "accurate".
(It is known to be out of date / out of synch in many cases)
2) To check for your site in the Search Engine Results,
a) please use the Site: operator = in Google search, in teh search box, type in site:www.yourdomain.tld or site:yourdomain.tld)
b) try doing a search for the <title> of a given page using quotes around it ( "your pages title" )
c) try doing a search for a snippet of "unique" content using quotes ( "just copy and paste a short sentence of so from one of your pages" )
3) If requesting help/assistance/information regarding your site and getting crawled/indexed - PLEASE supply relevant information.
Tell us when the site went live, whether you have actually Submitted the site, whether it is Verified, whether you supplied a Sitemap, whether you access to your Server Logs, whether you can see the GoogleBot crawling your site and what response code it gives etc. etc. etc.
