1 - Choose the wrong keywords
This is a mistake many people make and what is worse - even
experienced SEO experts do. People choose keywords that in
their mind are descriptive of their website, but the αβεραγε
users just can not look at them. For example, if you have a
relationship site, you may discover that "relationship guide"
does not work for you, though it has the "relationship" keyword,
while "dating advice" works like a charm. Choosing the right
keywords can make or break your SEO campaign. Even if you are
very clever, you can not think for yourself all the great
keywords but a tool keyword suggestion well, for example,
the Web keyword suggestion tool will help you find keywords that
are good for your site.
2 - Ignoring the Title tag
Leaving the "title" tag empty is also very common. This is one
of the most important places to have a keyword, because not only
helps you in optimization but the text in the "title" tag shows
in search results as the title of the page.
3 - A Flash website without a html alternative
Flash can be attractive, but not for search engines and users.
If you really insist that your site is Flash based and you want
search engines to love, provide an html version. Here are some
tips for optimizing Flash sites. Search engines do not like
Flash sites for a reason - a spider can not read
Flash content and therefore can not index it.
4 - The JavaScript menus
Using JavaScript for navigation is not bad as long as you
understand that search engines do not read JavaScript and
build your web pages accordingly. So if you have JavaScript
menus you can not live without, consider building a sitemap
(or putting the links in a noscript tag) so that all links
are crawlable.
5 - Lack of consistency and maintenance
Our friend Rob from Blackwood Productions often encounters
clients, who believe that once you optimize a site, it is
Foreve. If you want to succeed, you need to permanently
optimize your site, keep an eye on the competition and -
changes in the ranking algorithms of search engines.
6 - Focusing too much on meta tags
Many people seem to think that SEO is about getting your
meta keywords and description correct! In fact, meta tags
are becoming (if not already) a thing of the past. You can
create your meta keywords and descriptions, but no other than
this range and only.
7 - Using images only for titles
Many people think that a picture is better than text for
headings and menus. Yes, an image can make your site look
more distinctive but in terms of SEO images for headings
and menus are a big mistake because H2, H2, etc. tags
and menu links are important SEO items.
8 - Ignoring URLs
Many people underestimate the importance of a URL that is good.
Dynamic page names are still very frequent and no keywords in
the URL is more a rule than an exception. Yes, it is possible
that the top, even without words in the URL, but all things being
equal, if you have keywords in the URL (same domain, or file
names that are part of the URL), this will gives additional
advantage over its competitors. Keywords in URLs are more
important for MSN and Yahoo! , But even with Google their
relative weight is high, so there's no excuse to have the
URL keywordless.
9 - Backlink spam
It's a common misconception that the more backlinks is always
better and because of this web masters resort to link farms,
forum / newgroup spam etc., which ultimately could lead to get
your site banned. In fact, what you need are quality backlinks.
10 - Lack of keywords in the content
Once you focus on keywords, modify your content and keywords to
always make sense. It's even better to be bold or underline
them.
