Types of Tags:
a) The Title Tag
Whatever text is placed in the Title Tag will appear in your reverse bar (the top bar of your browser) when you view that web page. The Title Tag also comes in use when we bookmark or add a page to our favorites list. For instance, if you were to add this page to your favorites list, then it would appear by its Title, 'Search Engine Copywriting : Tips & Copywriting techniques for effective search engine copywriting'. For more information on Title Tag, read our article on Title Tag and Meta Description Tag Optimization.
Title Tag of 70 to 90 characters is appropriate.
b) Meta Description Tag
The Meta Description Tags allow you to manipulate, to a certain extent, the description of your page in some of the crawlers that support this Tag. I repeat 'to a certain extent' and only in 'some' of the search engines. Meta Description Tag of about 25 words should be fine. Read our detailed article on Title Tag and Meta Description Tag Optimization.
c) Meta Keywords Tag
The Meta Keywords Tag can contain about 15 important keywords. Search engines no longer read the Meta Keyword Tags. It's sufficient to have one on the home page (just in case). Read our article on Meta Tags Optimization for Search Engines
Other Useful Tips for SEO Copywriting
1. Update your content frequently, as some search engines index your content more often, if it is updated and kept fresh. But a better reason to do this is that when a user visits your site again, he should find new relevant information, which would bring him to your site again.
2. Have adequate HTML text on your home page with important keywords in the beginning. This is what search engines can read. For home page and important inner pages, about 250 words of text with keywords should be fine.
3. The best SEO copy written pages that rank highly on the search engines are the ones with the best information and content. These are kept so natural that a surfer, more than often does not even realize that they have been optimized.
SEO Copywriting and other kinds of copywriting don't always blend well, but that's exactly what SEO copywriter has to ensure, because SEO copywriting would only help in bringing people through the search engines to the website. Hence, it is essential to provide maximum information, so that people don't hit on the back button as soon as they visit your site!
